linux script命令的使用

平常记录终端里的一些命令log或操作记录等，script可以试试看：

script --help

Usage:
 script [options] [file]

Make a typescript of a terminal session.

Options:
 -a, --append                  append the output
 -c, --command <command>       run command rather than interactive shell
 -e, --return                  return exit code of the child process
 -f, --flush                   run flush after each write
     --force                   use output file even when it is a link
 -o, --output-limit <size>     terminate if output files exceed size
 -q, --quiet                   be quiet
 -t[<file>], --timing[=<file>] output timing data to stderr or to FILE
 -h, --help                    display this help
 -V, --version                 display version

For more details see script(1).

1. 记录log：

script -f note.log，输出到指定文件，可以边录log边看。-a则是追加记录到文件里。-t则是输出时序文件，适用于录过回放演示操作。

ex：script -f -t 2>time.log -a note.log

2. 回放log：

scriptreplay --help

Usage:
 scriptreplay [-t] timingfile [typescript] [divisor]

Play back terminal typescripts, using timing information.

Options:
 -t, --timing <file>     script timing output file
 -s, --typescript <file> script terminal session output file
 -d, --divisor <num>     speed up or slow down execution with time divisor
 -m, --maxdelay <num>    wait at most this many seconds between updates
 -h, --help              display this help
 -V, --version           display version

For more details see scriptreplay(1).

ex：scriptreplay time.log note.log

终端会输出刚才的操作记录。

注意time.log不能少且要放在note.log前面。

3. 退出

exit
Script done, file is note.log

PS：

还具有录制终端功能的tool：terminalizer

将录制的file做成gif文件：terminalizer、imagemagick(convert)
