SCRIPT(1) BSD General Commands Manual SCRIPT(1)
script - make typescript of terminal session
script [-a] [-c COMMAND] [-f] [-q] [-t] [file]
Script 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.
-a Append the output to file or typescript, retaining the prior con-
Run the COMMAND rather than an interactive shell. This makes it
easy for a script to capture the output of a program that behaves
differently when its stdout is not a tty.
-f Flush output after each write. This is nice for telecooperation:
One person does ‘mkfifo foo; script -f foo’ and another can
supervise real-time what is being done using ‘cat foo’.
-q Be quiet.
-t Output timeing data to standard error. This data contains two
fields, separated by a space. The first field indicates how much
time elapsed since the previous output. The second field indi-
cates how many characters were output this time. This information
can be used to replay typescripts with realistic typing and out-
The script ends when the forked shell 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. Script works best with commands that do not manipulate the
screen, the results are meant to emulate a hardcopy terminal.
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), scriptreplay(1).
The script command appeared in 3.0BSD.
Script places everything in the log file, including linefeeds and
backspaces. This is not what the naive user expects.
