復制代碼代碼如下:

amosli@amosli-pc:~/learn$ script -t 2> timing.log -a output.session#開始錄制
Script started, file is output.session
amosli@amosli-pc:~/learn$ hello1
No command 'hello1' found, did you mean:
Command 'hello' from package 'hello-debhelper' (main)
Command 'hello' from package 'hello' (main)
hello1: command not found
amosli@amosli-pc:~/learn$ who
amosli   tty7         2013-12-19 22:58
amosli   pts/1        2013-12-19 22:59 (:0.0)
amosli   pts/2        2013-12-19 23:16 (:0.0)
amosli@amosli-pc:~/learn$ time

real    0m0.000s
user    0m0.000s
sys    0m0.000s
amosli@amosli-pc:~/learn$ date
2013年 12月 20日星期五 01:06:41 CST
amosli@amosli-pc:~/learn$ exit
exit #結束錄制
Script done, file is output.session

播放錄制：

復制代碼代碼如下:

amosli@amosli-pc:~/learn$ scriptreplay timing.log output.session #按播放命令序列輸出
amosli@amosli-pc:~/learn$ hello1
No command 'hello1' found, did you mean:
Command 'hello' from package 'hello-debhelper' (main)
Command 'hello' from package 'hello' (main)
hello1: command not found
amosli@amosli-pc:~/learn$ who
amosli   tty7         2013-12-19 22:58
amosli   pts/1        2013-12-19 22:59 (:0.0)
amosli   pts/2        2013-12-19 23:16 (:0.0)
amosli@amosli-pc:~/learn$ time

real    0m0.000s
user    0m0.000s
sys    0m0.000s
amosli@amosli-pc:~/learn$ date
2013年 12月 20日星期五 01:06:41 CST
amosli@amosli-pc:~/learn$ exit
amosli@amosli-pc:~/learn$

進行多個用戶之間進行廣播視頻會話：打開兩個終端

(1)在終端１中輸入以下命令：

復制代碼代碼如下:

mkfifo scriptfifo

(2)在終端２中輸入以下命令:

復制代碼代碼如下:

cat scriptfifo

(3)返回終端１，輸入以下命令：

復制代碼代碼如下:

script -f scriptfifo
commands...

這樣就實現了廣播，在線課堂類的作用，非常神奇！！

我自己實驗的輸出：

復制代碼代碼如下:

終端１：
amosli@amosli-pc:~$ mkfifo scriptfifo
amosli@amosli-pc:~$ script -f scriptfifo
Script started, file is scriptfifo
amosli@amosli-pc:~$ who
amosli   tty7         2013-12-19 22:58
amosli   pts/1        2013-12-19 22:59 (:0.0)
amosli   pts/2        2013-12-20 01:14 (:0.0)
amosli   pts/4        2013-12-20 01:16 (:0.0)
amosli   pts/5        2013-12-20 01:20 (:0.0)
amosli   pts/6        2013-12-20 01:20 (:0.0)
amosli@amosli-pc:~$

終端２：
amosli@amosli-pc:~$ cat scriptfifo
Script started on 2013年12月20日星期五 01時21分19秒
amosli@amosli-pc:~$ who
amosli   tty7         2013-12-19 22:58
amosli   pts/1        2013-12-19 22:59 (:0.0)
amosli   pts/2        2013-12-20 01:14 (:0.0)
amosli   pts/4        2013-12-20 01:16 (:0.0)
amosli   pts/5        2013-12-20 01:20 (:0.0)
amosli   pts/6        2013-12-20 01:20 (:0.0)
