pico(1) 			     General Commands Manual				  pico(1)

Name
       pico - simple text editor in the style of the Pine Composer

Syntax
       pico [-f] [+n] [-nn] [-t] [-v] [-w] [-z] [file]

Description
       Pico  is a simple, display-oriented text editor based on the Pine message system composer.
       As with Pine, commands are displayed at the bottom of the  screen,  and	context-sensitive
       help  is  provided.   As characters are typed they are immediately inserted into the text.
       Editing commands are entered using control-key combinations.  As a work-around for  commu-
       nications  programs that swallow certain control characters, you can emulate a control key
       by pressing ESCAPE twice, followed by the desired control  character,  e.g.  "ESC  ESC  c"
       would  be  equivalent to entering a ctrl-c.  The editor has five basic features: paragraph
       justification, searching, block cut/paste, a spelling checker, and a file browser.

       Paragraph justification (or filling) takes place in the paragraph that contains	the  cur-
       sor,  or,  if the cursor is between lines, in the paragraph immediately below.  Paragraphs
       are delimited by blank lines, or by lines beginning with a space or tab.   Unjustification
       can be done immediately after justification using the control-U key combination.

       String searches are not sensitive to case.  A search begins at the current cursor position
       and wraps around the end of the text.  The most recent search string  is  offered  as  the
       default in subsequent searches.

       Blocks  of  text can be moved, copied or deleted with creative use of the command for mark
       (ctrl-underscore), delete (ctrl-k) and undelete (ctrl-u).  The delete command will  remove
       text between the "mark" and the current cursor position, and place it in the "cut" buffer.
       The undelete command effects a "paste" at the current cursor position.

       The spell checker examines all words in the text.  It then  offers,  in	turn,  each  mis-
       spelled word for correction while highlighting it in the text.  Spell checking can be can-
       celled at any time.  Alternatively, pico will substitute for the  default  spell  checking
       routine	a  routine  defined  by  the SPELL environment variable.  The replacement routine
       should read standard input and write standard output.

       The file browser is offered as an option in  the  "Read	File"  and  "Write  Out"  command
       prompts.   It is intended to help in searching for specific files and navigating directory
       hierarchies.  Filenames with sizes and names of directories in the current working  direc-
       tory  are  presented for selection.  The current working directory is displayed on the top
       line of the display while the list of available commands takes up the bottom two.  Several
       basic file manipulation functions are supported:  file renaming, copying, and deletion.

       More specific help is available in pico's online help.

Options
       -f     Use  function keys for commands.	This option supported only in conjunction with UW
	      Enhanced NCSA telnet.

       +n     Causes pico to be started with the cursor located n lines into the file. (Note:  no
	      space between "+" sign and number)

       -nn    The  -nn	option	enables  new  mail notification.  The n argument is optional, and
	      specifies how often, in seconds, your mailbox is checked for new mail.   For  exam-
	      ple,  -n60 causes pico to check for new mail once every minute.  The default inter-
	      val is 180 seconds, while the minimum allowed is 30. (Note: no  space  between  "n"
	      and the number)

       -t     Enable  "tool"  mode.   Intended	for  when pico is used as the editor within other
	      tools (e.g., Elm, Pnews).  Pico will not prompt for save	on  exit,  and	will  not
	      rename the buffer during the "Write Out" command.

       -v     View the file only, disallowing any editing.

       -w     Disable word wrap (thus allow editing of long lines).

       -z     Enable ^Z suspension of pico.

       Lastly,	when a running pico is disconnected (i.e., receives a SIGHUP), pico will save the
       current work if needed before exiting.  Work is saved  under  the  current  filename  with
       ".save"	appended.   If	the  current  work  is	unnamed,  it  is saved under the filename
       "pico.save".

Bugs
       The manner in which lines longer than the display width are dealt is not immediately obvi-
       ous.   Lines that continue beyond the edge of the display are indicated by a '$' character
       at the end of the line.	Long lines are scrolled horizontally as the cursor moves  through
       them.

Files
       pico.save	Unnamed interrupted work saved here.
       *.save		Interrupted work on a named file is saved here.
