NAME
     script -- make typescript of terminal session

SYNOPSIS
     script [-a] [-k] [-q] [-t time] [file [command ...]]

DESCRIPTION
     The script utility makes a typescript of everything printed on your terminal.  It is useful
     for students who need a hardcopy record of an interactive 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.

     Options:

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

     -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 typescript file.  The
     script utility works best with commands that do not manipulate the screen.  The results are
     meant to emulate a hardcopy terminal, not an addressable one.

ENVIRONMENT
     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 auto-
	    matically).

SEE ALSO
     csh(1) (for the history mechanism).

HISTORY
     The script command appeared in 3.0BSD.

BUGS
     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 argu-
     ment 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.
