SCRIPT(1)		  BSD General Commands Manual		     SCRIPT(1)

     script -- make typescript of terminal session

     script [-akq] [-t time] [file [command ...]]

     The script	utility	makes a	typescript of everything printed on your ter-
     minal.  It	is useful for students who need	a hardcopy record of an	inter-
     active session as proof of	an assignment, as the typescript file can be
     printed out later with lpr(1).

     If	the argument file is given, script saves all dialogue in file.	If no
     file name is given, the typescript	is saved in the	file typescript.

     If	the argument command is	given, script will run the specified command
     with an optional argument vector instead of an interactive	shell.

     The following options are available:

     -a	     Append the	output to file or typescript, retaining	the prior con-

     -k	     Log keys sent to program as well as output.

     -q	     Run in quiet mode,	omit the start and stop	status messages.

     -t	time
	     Specify time interval between flushing script output file.	 A
	     value of 0	causes script to flush for every character I/O event.
	     The default interval is 30	seconds.

     The script	ends when the forked shell (or command)	exits (a control-D to
     exit the Bourne shell (sh(1)), and	exit, logout or	control-D (if
     ignoreeof is not set) for the C-shell, csh(1)).

     Certain interactive commands, such	as vi(1), create garbage in the	type-
     script file.  The script utility works best with commands that do not ma-
     nipulate the screen.  The results are meant to emulate a hardcopy termi-
     nal, not an addressable one.

     The following environment variable	is utilized by script:

     SHELL  If the variable SHELL exists, the shell forked by script will be
	    that shell.	 If SHELL is not set, the Bourne shell is assumed.
	    (Most shells set this variable automatically).

     csh(1) (for the history mechanism).

     The script	command	appeared in 3.0BSD.

     The script	utility	places everything in the log file, including linefeeds
     and backspaces.  This is not what the naive user expects.

     It	is not possible	to specify a command without also naming the script
     file because of argument parsing compatibility issues.

     When running in -k	mode, echo cancelling is far from ideal.  The slave
     terminal mode is checked for ECHO mode to check when to avoid manual echo
     logging.  This does not work when in a raw	mode where the program being
     run is doing manual echo.
