linux下script命令能够录制击键以及击键时机，并将输入和输出结果保存在对应的文件中；scriptreplay可以回放记录。这两个命令在绝大多数的GUN/Linux发型版上都可以找到，通过录制终端记录来制作命令行技巧视频，也可分享回话记录文件。另还可以调用其他解释器并录制发送给该解释器的击键。
srcript
说下常用的选项，更详细的说明可以man script来查看
| 选项 | 描述 |
|---|---|
| -a, - -append | 输出录制的文件，在现有内容上追加新的内容 |
| -c, - -command | 直接执行命令，而非是交互式的shell |
| -r, - -return | 返回子shell的退出码 |
| -f, - -flush | 每次操作后都立即刷新缓存。 如果不设置这个选项，则不会实时写入文件 |
| -q, - -quiet | 可以使script命令以静默模式运行，不显示script启动和exit的命令，用户可以完全察觉不到在录屏 |
| -t, - -timing[=<file>] | 输出录制的时间数据，输出到屏幕或者存到指定文件中，回放的时候用到 |
| -V, - -version | 显示版本并退出 |
| -h, - -help | 显示使用说明并退出 |
scriptreplay
| 选项 | 描述 |
|---|---|
| -t, - -timing file | 包含记录时序的文件 |
| -s, - -typescript file | 包含脚本终端输出的文件 |
| -d, –divisor number | 加速播放速度倍数（可以是小数：放慢） |
| -V, - -version | 显示版本并退出 |
| -h, - -help | 显示使用说明并退出 |

录制文件
直接使用script命令，记录在默认文件中：typescript
[root@localhost ~]# script
Script started, file is typescript
[root@localhost ~]# pwd
/root
[root@localhost ~]# ls
anaconda-ks.cfg bindcpu execShell.sh original-ks.cfg soft typescript
[root@localhost ~]# ./execShell.sh
pwd:/root
date:Fri Jul 6 13:54:38 CST 2018
[root@localhost ~]# exit
exit
Script done, file is typescript
[root@localhost ~]#
[root@localhost ~]# cat typescript
Script started on Fri 06 Jul 2018 01:55:31 PM CST
[root@localhost ~]# pwd
/root
[root@localhost ~]# ls
anaconda-ks.cfg bindcpu execShell.sh original-ks.cfg soft typescript
[root@localhost ~]# ./execShell.sh
pwd:/root
date:Fri Jul 6 13:55:41 CST 2018
[root@localhost ~]# exit
exit
Script done on Fri 06 Jul 2018 01:55:44 PM CST
[root@localhost ~]# 再次执行script命令，文件typescript被重写
[root@localhost ~]# script
Script started, file is typescript
[root@localhost ~]# ls
anaconda-ks.cfg bindcpu execShell.sh original-ks.cfg soft typescript
[root@localhost ~]# ls
anaconda-ks.cfg bindcpu execShell.sh original-ks.cfg soft typescript
[root@localhost ~]# exit
exit
Script done, file is typescript
[root@localhost ~]# cat typescript
Script started on Fri 06 Jul 2018 02:00:57 PM CST
[root@localhost ~]# ls
anaconda-ks.cfg bindcpu execShell.sh original-ks.cfg soft typescript
[root@localhost ~]# ls
anaconda-ks.cfg bindcpu execShell.sh original-ks.cfg soft typescript
[root@localhost ~]# exit
exit
Script done on Fri 06 Jul 2018 02:01:03 PM CST
[root@localhost ~]# 可以使用-a参数,记录追加在文件
[root@localhost ~]# script -a
Script started, file is typescript
[root@localhost ~]# echo "more"
more
[root@localhost ~]# exit
exit
Script done, file is typescript
[root@localhost ~]# cat typescript
Script started on Fri 06 Jul 2018 02:00:57 PM CST
[root@localhost ~]# ls

Script started on Fri 06 Jul 2018 02:02:07 PM CST
[root@localhost ~]# echo "more"
more
[root@localhost ~]# exit
exit
Script done on Fri 06 Jul 2018 02:02:21 PM CST
[root@localhost ~]# 指定文件名称输出
[root@localhost ~]# script outRename.out
Script started, file is outRename.out
[root@localhost ~]# ls
anaconda-ks.cfg bindcpu execShell.sh original-ks.cfg outRename.out soft typescript
[root@localhost ~]# exit
exit
Script done, file is outRename.out
[root@localhost ~]# cat outRename.out
Script started on Fri 06 Jul 2018 02:06:19 PM CST
[root@localhost ~]# ls
anaconda-ks.cfg bindcpu execShell.sh original-ks.cfg outRename.out soft typescript
[root@localhost ~]# exit
exit
Script done on Fri 06 Jul 2018 02:06:23 PM CST
[root@localhost ~]# 记录时序
清理一下输出记录文件，然后执行如下命令:
[root@localhost ~]# script -a outRename.out -t 2>timeSeq.out
Script started, file is outRename.out
[root@localhost ~]# pwd
/root
[root@localhost ~]# ./execShell.sh
pwd:/root
date:Fri Jul 6 14:09:37 CST 2018
[root@localhost ~]# exit
exit
Script done, file is outRename.out
[root@localhost ~]#
[root@localhost ~]# cat outRename.out
Script started on Fri 06 Jul 2018 02:09:29 PM CST
[root@localhost ~]# pwd
/root
[root@localhost ~]# ./execShell.sh
pwd:/root
date:Fri Jul 6 14:09:37 CST 2018
[root@localhost ~]# exit
exit

[root@localhost ~]# 直接执行命令不使用shell交互
[root@localhost ~]# script -c ls -a c.out -t 2>cSeq.out
Script started, file is c.out
anaconda-ks.cfg bindcpu c.out cSeq.out execShell.sh original-ks.cfg outRename.out soft timeSeq.out
Script done, file is c.out
[root@localhost ~]# cat c.out
Script started on Fri 06 Jul 2018 02:12:58 PM CST
anaconda-ks.cfg bindcpu c.out cSeq.out execShell.sh original-ks.cfg outRename.out soft timeSeq.out
Script done on Fri 06 Jul 2018 02:12:58 PM CST
[root@localhost ~]# 使用静默模式
[root@localhost ~]# script -q q.out -t 2>qSeq.out
[root@localhost ~]# ls
anaconda-ks.cfg bindcpu execShell.sh original-ks.cfg q.out qSeq.out soft
[root@localhost ~]# exit
exit
[root@localhost ~]# cat q.out
Script started on Fri 06 Jul 2018 02:16:20 PM CST
[root@localhost ~]# ls
anaconda-ks.cfg bindcpu execShell.sh original-ks.cfg q.out qSeq.out soft
[root@localhost ~]# exit
exit
[root@localhost ~]# 对比使用静默模式的记录文件，没有记录开始和推出的相关信息
scriptreplay
使用上一步中的文件
[root@localhost ~]# scriptreplay -t qSeq.out -s q.out
[root@localhost ~]# ls
anaconda-ks.cfg bindcpu execShell.sh original-ks.cfg q.out qSeq.out soft
[root@localhost ~]# exit
[root@localhost ~]# [root@localhost ~]# scriptreplay -t qSeq.out -s q.out -d 0.5
[root@localhost ~]# ls
anaconda-ks.cfg bindcpu execShell.sh original-ks.cfg q.out qSeq.out soft
[root@localhost ~]# exit
[root@localhost ~]# scriptreplay -t qSeq.out -s q.out -d 2
[root@localhost ~]# ls
anaconda-ks.cfg bindcpu execShell.sh original-ks.cfg q.out qSeq.out soft
[root@localhost ~]# exit
