script - make typescript of terminal session
script [options] [file]
script makes a typescript of everything printed on your terminal. It is useful for stu-
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 typescript is saved in the file typescript.
Append the output to file or typescript, retaining the prior contents.
-c, --command command
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
Return the exit code of the child process. Uses the same format as bash termina-
tion on signal termination exit code is 128+n.
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'.
Allow the default output destination, i.e. the typescript file, to be a hard or
symbolic link. The command will follow a symbolic link.
Output timing data to standard error, or to file when given. This data contains
two fields, separated by a space. The first field indicates how much time elapsed
since the previous output. The second field indicates how many characters were
output this time. This information can be used to replay typescripts with realis-
tic typing and output delays.
Output version information and exit.
Output help and exit.
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 typescript 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
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.
The script command is part of the util-linux package and is available from Linux Kernel
