SCRIPT(1) BSD General Commands Manual SCRIPT(1)
NAME
script -- make typescript of terminal session
SYNOPSIS
script [-akq] [-t time] [file [command ...]]
DESCRIPTION
The script utility makes a typescript of everything printed on your terminal. It is useful for stu-dents students
dents 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 type-script typescript
script is saved in the file typescript.
If the argument command is given, script will run the specified command with an optional argument vec-tor vector
tor instead of an interactive shell.
The following options are available:
-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 hard-copy hardcopy
copy 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 automatically).
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 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.
