pterm - yet another X terminal emulator SYNOPSIS
pterm [ options ] DESCRIPTION
pterm is a terminal emulator for X. It is based on a port of the terminal emulation engine in the Windows SSH client PuTTY. OPTIONS
The command-line options supported by pterm are: -e command [ arguments ] Specify a command to be executed in the new terminal. Everything on the command line after this option will be passed straight to the execvp system call; so if you need the command to redirect its input or output, you will have to use sh: pterm -e sh -c 'mycommand < inputfile' --display display-name Specify the X display on which to open pterm. (Note this option has a double minus sign, even though none of the others do. This is because this option is supplied automatically by GTK. Sorry.) -name name Specify the name under which pterm looks up X resources. Normally it will look them up as (for example) pterm.Font. If you specify `-name xyz', it will look them up as xyz.Font instead. This allows you to set up several different sets of defaults and choose between them. -fn font-name Specify the font to use for normal text displayed in the terminal. -fb font-name Specify the font to use for bold text displayed in the terminal. If the BoldAsColour resource is set to 1 (the default), bold text will be displayed in different colours instead of a different font, so this option will be ignored. If BoldAsColour is set to 0 and you do not specify a bold font, pterm will overprint the normal font to make it look bolder. -fw font-name Specify the font to use for double-width characters (typically Chinese, Japanese and Korean text) displayed in the terminal. -fwb font-name Specify the font to use for bold double-width characters (typically Chinese, Japanese and Korean text). Like -fb, this will be ignored unless the BoldAsColour resource is set to 0. -geometry geometry Specify the size of the terminal, in rows and columns of text. See X(7) for more information on the syntax of geometry specifica- tions. -sl lines Specify the number of lines of scrollback to save off the top of the terminal. -fg colour Specify the foreground colour to use for normal text. -bg colour Specify the background colour to use for normal text. -bfg colour Specify the foreground colour to use for bold text, if the BoldAsColour resource is set to 1 (the default). -bbg colour Specify the foreground colour to use for bold reverse-video text, if the BoldAsColour resource is set to 1 (the default). (This colour is best thought of as the bold version of the background colour; so it only appears when text is displayed in the background colour.) -cfg colour Specify the foreground colour to use for text covered by the cursor. -cbg colour Specify the background colour to use for text covered by the cursor. In other words, this is the main colour of the cursor. -title title Specify the initial title of the terminal window. (This can be changed under control of the server.) -ut- or +ut Tells pterm not to record your login in the utmp, wtmp and lastlog system log files; so you will not show up on finger or who list- ings, for example. -ut Tells pterm to record your login in utmp, wtmp and lastlog: this is the opposite of -ut-. This is the default option: you will prob- ably only need to specify it explicitly if you have changed the default using the StampUtmp resource. -ls- or +ls Tells pterm not to execute your shell as a login shell. -ls Tells pterm to execute your shell as a login shell: this is the opposite of -ls-. This is the default option: you will probably only need to specify it explicitly if you have changed the default using the LoginShell resource. -sb- or +sb Tells pterm not to display a scroll bar. -sb Tells pterm to display a scroll bar: this is the opposite of -sb-. This is the default option: you will probably only need to spec- ify it explicitly if you have changed the default using the ScrollBar resource. -log filename This option makes pterm log all the terminal output to a file as well as displaying it in the terminal. -cs charset This option specifies the character set in which pterm should assume the session is operating. This character set will be used to interpret all the data received from the session, and all input you type or paste into pterm will be converted into this character set before being sent to the session. Any character set name which is valid in a MIME header (and supported by pterm) should be valid here (examples are `ISO-8859-1', `windows-1252' or `UTF-8'). Also, any character encoding which is valid in an X logical font description should be valid (`ibm- cp437', for example). pterm's default behaviour is to use the same character encoding as its primary font. If you supply a Unicode (iso10646-1) font, it will default to the UTF-8 character set. Character set names are case-insensitive. -nethack Tells pterm to enable NetHack keypad mode, in which the numeric keypad generates the NetHack hjklyubn direction keys. This enables you to play NetHack with the numeric keypad without having to use the NetHack number_pad option (which requires you to press `n' before any repeat count). So you can move with the numeric keypad, and enter repeat counts with the normal number keys. -xrm resource-string This option specifies an X resource string. Useful for setting resources which do not have their own command-line options. For exam- ple: pterm -xrm 'ScrollbarOnLeft: 1' -help, --help Display a message summarizing the available options. -pgpfp Display the fingerprints of the PuTTY PGP Master Keys, to aid in verifying new files released by the PuTTY team. X RESOURCES
pterm can be more completely configured by means of X resources. All of these resources are of the form pterm.FOO for some FOO; you can make pterm look them up under another name, such as xyz.FOO, by specifying the command-line option `-name xyz'. pterm.CloseOnExit This option should be set to 0, 1 or 2; the default is 2. It controls what pterm does when the process running inside it terminates. When set to 2 (the default), pterm will close its window as soon as the process inside it terminates. When set to 0, pterm will print the process's exit status, and the window will remain present until a key is pressed (allowing you to inspect the scrollback, and copy and paste text out of it). When this setting is set to 1, pterm will close immediately if the process exits cleanly (with an exit status of zero), but the win- dow will stay around if the process exits with a non-zero code or on a signal. This enables you to see what went wrong if the process suffers an error, but not to have to bother closing the window in normal circumstances. pterm.WarnOnClose This option should be set to either 0 or 1; the default is 1. When set to 1, pterm will ask for confirmation before closing its win- dow when you press the close button. pterm.TerminalType This controls the value set in the TERM environment variable inside the new terminal. The default is `xterm'. pterm.BackspaceIsDelete This option should be set to either 0 or 1; the default is 1. When set to 0, the ordinary Backspace key generates the Backspace character (^H); when set to 1, it generates the Delete character (^?). Whichever one you set, the terminal device inside pterm will be set up to expect it. pterm.RXVTHomeEnd This option should be set to either 0 or 1; the default is 0. When it is set to 1, the Home and End keys generate the control sequences they would generate in the rxvt terminal emulator, instead of the more usual ones generated by other emulators. pterm.LinuxFunctionKeys This option can be set to any number between 0 and 5 inclusive; the default is 0. The modes vary the control sequences sent by the function keys; for more complete documentation, it is probably simplest to try each option in `pterm -e cat', and press the keys to see what they generate. pterm.NoApplicationKeys This option should be set to either 0 or 1; the default is 0. When set to 1, it stops the server from ever switching the numeric keypad into application mode (where the keys send function-key-like sequences instead of numbers or arrow keys). You probably only need this if some application is making a nuisance of itself. pterm.NoApplicationCursors This option should be set to either 0 or 1; the default is 0. When set to 1, it stops the server from ever switching the cursor keys into application mode (where the keys send slightly different sequences). You probably only need this if some application is making a nuisance of itself. pterm.NoMouseReporting This option should be set to either 0 or 1; the default is 0. When set to 1, it stops the server from ever enabling mouse reporting mode (where mouse clicks are sent to the application instead of controlling cut and paste). pterm.NoRemoteResize This option should be set to either 0 or 1; the default is 0. When set to 1, it stops the server from being able to remotely control the size of the pterm window. pterm.NoAltScreen This option should be set to either 0 or 1; the default is 0. When set to 1, it stops the server from using the `alternate screen' terminal feature, which lets full-screen applications leave the screen exactly the way they found it. pterm.NoRemoteWinTitle This option should be set to either 0 or 1; the default is 0. When set to 1, it stops the server from remotely controlling the title of the pterm window. pterm.NoRemoteQTitle This option should be set to either 0 or 1; the default is 1. When set to 1, it stops the server from remotely requesting the title of the pterm window. This feature is a POTENTIAL SECURITY HAZARD. If a malicious application can write data to your terminal (for example, if you merely cat a file owned by someone else on the server machine), it can change your window title (unless you have disabled this using the NoRemoteWinTitle resource) and then use this service to have the new window title sent back to the server as if typed at the key- board. This allows an attacker to fake keypresses and potentially cause your server-side applications to do things you didn't want. Therefore this feature is disabled by default, and we recommend you do not turn it on unless you really know what you are doing. pterm.NoDBackspace This option should be set to either 0 or 1; the default is 0. When set to 1, it disables the normal action of the Delete (^?) char- acter when sent from the server to the terminal, which is to move the cursor left by one space and erase the character now under it. pterm.ApplicationCursorKeys This option should be set to either 0 or 1; the default is 0. When set to 1, the default initial state of the cursor keys are appli- cation mode (where the keys send function-key-like sequences instead of numbers or arrow keys). When set to 0, the default state is the normal one. pterm.ApplicationKeypad This option should be set to either 0 or 1; the default is 0. When set to 1, the default initial state of the numeric keypad is application mode (where the keys send function-key-like sequences instead of numbers or arrow keys). When set to 0, the default state is the normal one. pterm.NetHackKeypad This option should be set to either 0 or 1; the default is 0. When set to 1, the numeric keypad operates in NetHack mode. This is equivalent to the -nethack command-line option. pterm.Answerback This option controls the string which the terminal sends in response to receiving the ^E character (`tell me about yourself'). By default this string is `PuTTY'. pterm.HideMousePtr This option should be set to either 0 or 1; the default is 0. When it is set to 1, the mouse pointer will disappear if it is over the pterm window and you press a key. It will reappear as soon as you move it. pterm.WindowBorder This option controls the number of pixels of space between the text in the pterm window and the window frame. The default is 1. You can increase this value, but decreasing it to 0 is not recommended because it can cause the window manager's size hints to work incorrectly. pterm.CurType This option should be set to either 0, 1 or 2; the default is 0. When set to 0, the text cursor displayed in the window is a rectan- gular block. When set to 1, the cursor is an underline; when set to 2, it is a vertical line. pterm.BlinkCur This option should be set to either 0 or 1; the default is 0. When it is set to 1, the text cursor will blink when the window is active. pterm.Beep This option should be set to either 0 or 2 (yes, 2); the default is 0. When it is set to 2, pterm will respond to a bell character (^G) by flashing the window instead of beeping. pterm.BellOverload This option should be set to either 0 or 1; the default is 0. When it is set to 1, pterm will watch out for large numbers of bells arriving in a short time and will temporarily disable the bell until they stop. The idea is that if you cat a binary file, the fran- tic beeping will mostly be silenced by this feature and will not drive you crazy. The bell overload mode is activated by receiving N bells in time T; after a further time S without any bells, overload mode will turn itself off again. Bell overload mode is always deactivated by any keypress in the terminal. This means it can respond to large unexpected streams of data, but does not interfere with ordinary command-line activities that generate beeps (such as filename completion). pterm.BellOverloadN This option counts the number of bell characters which will activate bell overload if they are received within a length of time T. The default is 5. pterm.BellOverloadT This option specifies the time period in which receiving N or more bells will activate bell overload mode. It is measured in microseconds, so (for example) set it to 1000000 for one second. The default is 2000000 (two seconds). pterm.BellOverloadS This option specifies the time period of silence required to turn off bell overload mode. It is measured in microseconds, so (for example) set it to 1000000 for one second. The default is 5000000 (five seconds of silence). pterm.ScrollbackLines This option specifies how many lines of scrollback to save above the visible terminal screen. The default is 200. This resource is equivalent to the -sl command-line option. pterm.DECOriginMode This option should be set to either 0 or 1; the default is 0. It specifies the default state of DEC Origin Mode. (If you don't know what that means, you probably don't need to mess with it.) pterm.AutoWrapMode This option should be set to either 0 or 1; the default is 1. It specifies the default state of auto wrap mode. When set to 1, very long lines will wrap over to the next line on the terminal; when set to 0, long lines will be squashed against the right-hand edge of the screen. pterm.LFImpliesCR This option should be set to either 0 or 1; the default is 0. When set to 1, the terminal will return the cursor to the left side of the screen when it receives a line feed character. pterm.WinTitle This resource is the same as the -T command-line option: it controls the initial title of the window. The default is `pterm'. pterm.TermWidth This resource is the same as the width part of the -geometry command-line option: it controls the number of columns of text in the window. The default is 80. pterm.TermHeight This resource is the same as the width part of the -geometry command-line option: it controls the number of columns of text in the window. The defaults is 24. pterm.Font This resource is the same as the -fn command-line option: it controls the font used to display normal text. The default is `fixed'. pterm.BoldFont This resource is the same as the -fb command-line option: it controls the font used to display bold text when BoldAsColour is turned off. The default is unset (the font will be bolded by printing it twice at a one-pixel offset). pterm.WideFont This resource is the same as the -fw command-line option: it controls the font used to display double-width characters. The default is unset (double-width characters cannot be displayed). pterm.WideBoldFont This resource is the same as the -fwb command-line option: it controls the font used to display double-width characters in bold, when BoldAsColour is turned off. The default is unset (double-width characters are displayed in bold by printing them twice at a one-pixel offset). pterm.ShadowBoldOffset This resource can be set to an integer; the default is -1. It specifies the offset at which text is overprinted when using `shadow bold' mode. The default (1) means that the text will be printed in the normal place, and also one character to the right; this seems to work well for most X bitmap fonts, which have a blank line of pixels down the right-hand side. For some fonts, you may need to set this to -1, so that the text is overprinted one pixel to the left; for really large fonts, you may want to set it higher than 1 (in one direction or the other). pterm.BoldAsColour This option should be set to either 0 or 1; the default is 1. It specifies the default state of auto wrap mode. When set to 1, bold text is shown by displaying it in a brighter colour; when set to 0, bold text is shown by displaying it in a heavier font. pterm.Colour0, pterm.Colour1, ..., pterm.Colour21 These options control the various colours used to display text in the pterm window. Each one should be specified as a triple of dec- imal numbers giving red, green and blue values: so that black is `0,0,0', white is `255,255,255', red is `255,0,0' and so on. Colours 0 and 1 specify the foreground colour and its bold equivalent (the -fg and -bfg command-line options). Colours 2 and 3 spec- ify the background colour and its bold equivalent (the -bg and -bbg command-line options). Colours 4 and 5 specify the text and block colours used for the cursor (the -cfg and -cbg command-line options). Each even number from 6 to 20 inclusive specifies the colour to be used for one of the ANSI primary colour specifications (black, red, green, yellow, blue, magenta, cyan, white, in that order); the odd numbers from 7 to 21 inclusive specify the bold version of each colour, in the same order. The defaults are: pterm.Colour0: 187,187,187 pterm.Colour1: 255,255,255 pterm.Colour2: 0,0,0 pterm.Colour3: 85,85,85 pterm.Colour4: 0,0,0 pterm.Colour5: 0,255,0 pterm.Colour6: 0,0,0 pterm.Colour7: 85,85,85 pterm.Colour8: 187,0,0 pterm.Colour9: 255,85,85 pterm.Colour10: 0,187,0 pterm.Colour11: 85,255,85 pterm.Colour12: 187,187,0 pterm.Colour13: 255,255,85 pterm.Colour14: 0,0,187 pterm.Colour15: 85,85,255 pterm.Colour16: 187,0,187 pterm.Colour17: 255,85,255 pterm.Colour18: 0,187,187 pterm.Colour19: 85,255,255 pterm.Colour20: 187,187,187 pterm.Colour21: 255,255,255 pterm.RectSelect This option should be set to either 0 or 1; the default is 0. When set to 0, dragging the mouse over several lines selects to the end of each line and from the beginning of the next; when set to 1, dragging the mouse over several lines selects a rectangular region. In each case, holding down Alt while dragging gives the other behaviour. pterm.MouseOverride This option should be set to either 0 or 1; the default is 1. When set to 1, if the application requests mouse tracking (so that mouse clicks are sent to it instead of doing selection), holding down Shift will revert the mouse to normal selection. When set to 0, mouse tracking completely disables selection. pterm.Printer This option is unset by default. If you set it, then server-controlled printing is enabled: the server can send control sequences to request data to be sent to a printer. That data will be piped into the command you specify here; so you might want to set it to `lpr', for example, or `lpr -Pmyprinter'. pterm.ScrollBar This option should be set to either 0 or 1; the default is 1. When set to 0, the scrollbar is hidden (although Shift-PageUp and Shift-PageDown still work). This is the same as the -sb command-line option. pterm.ScrollbarOnLeft This option should be set to either 0 or 1; the default is 0. When set to 1, the scrollbar will be displayed on the left of the ter- minal instead of on the right. pterm.ScrollOnKey This option should be set to either 0 or 1; the default is 0. When set to 1, any keypress causes the position of the scrollback to be reset to the very bottom. pterm.ScrollOnDisp This option should be set to either 0 or 1; the default is 1. When set to 1, any activity in the display causes the position of the scrollback to be reset to the very bottom. pterm.LineCodePage This option specifies the character set to be used for the session. This is the same as the -cs command-line option. pterm.NoRemoteCharset This option disables the terminal's ability to change its character set when it receives escape sequences telling it to. You might need to do this to interoperate with programs which incorrectly change the character set to something they think is sensible. pterm.BCE This option should be set to either 0 or 1; the default is 1. When set to 1, the various control sequences that erase parts of the terminal display will erase in whatever the current background colour is; when set to 0, they will erase in black always. pterm.BlinkText This option should be set to either 0 or 1; the default is 0. When set to 1, text specified as blinking by the server will actually blink on and off; when set to 0, pterm will use the less distracting approach of making the text's background colour bold. pterm.StampUtmp This option should be set to either 0 or 1; the default is 1. When set to 1, pterm will log the login in the various system log files. This resource is equivalent to the -ut command-line option. pterm.LoginShell This option should be set to either 0 or 1; the default is 1. When set to 1, pterm will execute your shell as a login shell. This resource is equivalent to the -ls command-line option. BUGS
Most of the X resources have silly names. (Historical reasons from PuTTY, mostly.) PuTTY tool suite 2004-03-24 pterm(1)
