TPUT(1) BSD General Commands Manual TPUT(1) NAME
tput, clear -- terminal capability interface SYNOPSIS
tput [-T term] attribute [attribute-args] ... DESCRIPTION
tput makes terminal-dependent information available to users or shell applications. The options are as follows: -T The terminal name as specified in the terminfo(5) database, for example, ``vt100'' or ``xterm''. If not specified, tput retrieves the ``TERM'' variable from the environment. tput outputs a string if the attribute is of type string; a number if it is of type integer. Otherwise, tput exits 0 if the terminal has the capability and 1 if it does not, without further action. If the attribute is of type string, and takes arguments (e.g. cursor movement, the terminfo ``cup'' sequence) the arguments are taken from the command line immediately following the attribute. The following special attributes are available: clear Clear the screen (the terminfo(5) ``cl'' sequence). init Initialize the terminal (the terminfo(5) ``is2'' sequence). longname Print the descriptive name of the user's terminal type. reset Reset the terminal (the terminfo(5) ``rs1, rs2, rs3'' and ``rf'' sequence). EXIT STATUS
The exit status of tput is based on the last attribute specified. If the attribute is of type string or of type integer, tput exits 0 if the attribute is defined for this terminal type and 1 if it is not. If the attribute is of type boolean, tput exits 0 if the terminal has this attribute, and 1 if it does not. tput exits 2 if any error occurred. EXAMPLES
tput cl cm 5 10 clear the screen and goto line 5 column 10 tput cm 6 11 DC 6 goto line 6 column 11 and delete 6 characters SEE ALSO
termcap(3), termcap(5) HISTORY
The tput command appears in 4.4BSD. BUGS
tput can't really distinguish between different types of attributes. Not all terminfo entries contain the reset sequence, so using the init sequence may be more useful. BSD

tput(1) User Commands tput(1) NAME
tput - initialize a terminal or query terminfo database SYNOPSIS
tput [-T type] capname [parm]... tput -S << DESCRIPTION
The tput utility uses the terminfo database to make the values of terminal-dependent capabilities and information available to the shell (see sh(1)); to clear, initialize or reset the terminal; or to return the long name of the requested terminal type. tput outputs a string if the capability attribute (capname) is of type string, or an integer if the attribute is of type integer. If the attribute is of type boolean, tput simply sets the exit status (0 for TRUE if the terminal has the capability, 1 for FALSE if it does not), and produces no out- put. Before using a value returned on standard output, the user should test the exit status ($?, see sh(1)) to be sure it is 0. See the EXIT STATUS section. OPTIONS
The following options are supported: -Ttype Indicates the type of terminal. Normally this option is unnecessary, because the default is taken from the environment variable TERM. If -T is specified, then the shell variables LINES and COLUMNS and the layer size will not be referenced. -S Allows more than one capability per invocation of tput. The capabilities must be passed to tput from the standard input instead of from the command line (see the example in the EXAMPLES section). Only one capname is allowed per line. The -S option changes the meaning of the 0 and 1 boolean and string exit statuses (see the EXAMPLES section). OPERANDS
The following operands are supported: capname Indicates the capability attribute from the terminfo database. See terminfo(4) for a complete list of capabilities and the cap- name associated with each. The following strings will be supported as operands by the implementation in the "C" locale: clear Display the clear-screen sequence. init If the terminfo database is present and an entry for the user's terminal exists (see -Ttype, above), the following will occur: 1. if present, the terminal's initialization strings will be output (is1, is2, is3, if, iprog), 2. any delays (for instance, newline) specified in the entry will be set in the tty driver, 3. tabs expansion will be turned on or off according to the specification in the entry, and 4. if tabs are not expanded, standard tabs will be set (every 8 spaces). If an entry does not contain the information needed for any of the four above activities, that activity will silently be skipped. reset Instead of putting out initialization strings, the terminal's reset strings will be output if present (rs1, rs2, rs3, rf). If the reset strings are not present, but initialization strings are, the initialization strings will be output. Otherwise, reset acts identically to init. longname If the terminfo database is present and an entry for the user's terminal exists (see -Ttype above), then the long name of the terminal will be put out. The long name is the last name in the first line of the terminal's descrip- tion in the terminfo database (see term(5)). parm If the attribute is a string that takes parameters, the argument parm will be instantiated into the string. An all numeric argument will be passed to the attribute as a number. EXAMPLES
Example 1 Initializing the terminal according to TERM This example initializes the terminal according to the type of terminal in the environment variable TERM. This command should be included in everyone's .profile after the environment variable TERM has been exported, as illustrated on the profile(4) manual page. example% tput init Example 2 Resetting a terminal This example resets an AT&T 5620 terminal, overriding the type of terminal in the environment variable TERM: example% tput -T5620 reset Example 3 Moving the cursor The following example sends the sequence to move the cursor to row 0, column 0 (the upper left corner of the screen, usually known as the "home" cursor position). example% tput cup 0 0 This next example sends the sequence to move the cursor to row 23, column 4. example% tput cup 23 4 Example 4 Echoing the clear-screen sequence This example echos the clear-screen sequence for the current terminal. example% tput clear Example 5 Printing the number of columns This command prints the number of columns for the current terminal. example% tput cols The following command prints the number of columns for the 450 terminal. example% tput -T450 cols Example 6 Setting shell variables This example sets the shell variables bold, to begin stand-out mode sequence, and offbold, to end standout mode sequence, for the current terminal. This might be followed by a prompt: echo "${bold}Please type in your name: ${offbold}c" example% bold='tput smso' example% offbold='tput rmso' Example 7 Setting the exit status This example sets the exit status to indicate if the current terminal is a hardcopy terminal. example% tput hc Example 8 Printing the long name from terminfo This command prints the long name from the terminfo database for the type of terminal specified in the environment variable TERM. example% tput longname Example 9 Processing several capabilities with one invocation This example shows tput processing several capabilities in one invocation. This example clears the screen, moves the cursor to position 10, 10 and turns on bold (extra bright) mode. The list is terminated by an exclamation mark (!) on a line by itself. example% tput -S <<! > clear > cup 10 10 > bold > ! ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of tput: LANG, LC_ALL, LC_CTYPE, LC_MES- SAGES, and NLSPATH. TERM Determine the terminal type. If this variable is unset or null, and if the -T option is not specified, an unspecified default ter- minal type will be used. EXIT STATUS
The following exit values are returned: 0 o If capname is of type boolean and -S is not specified, indicates TRUE. o If capname is of type string and -S is not specified, indicates capname is defined for this terminal type. o If capname is of type boolean or string and -S is specified, indicates that all lines were successful. o capname is of type integer. o The requested string was written successfully. 1 o If capname is of type boolean and -S is not specified, indicates FALSE. o If capname is of type string and -S is not specified, indicates that capname is not defined for this terminal type. 2 Usage error. 3 No information is available about the specified terminal type. 4 The specified operand is invalid. >4 An error occurred. -1 capname is a numeric variable that is not specified in the terminfo database. For instance, tput -T450 lines and tput -T2621 xmc. FILES
