Hi,

I''m new to Linux environment. I''m trying to get all commands executed by user and place it in a file. What I thought to do is read the value from stdin & directly place it in one file. But I don''t know how to read from stdin using script.

Please help me..
Thanks in advance:)

推荐答案

该外壳程序具有一个名为脚本"的命令，该命令将输入​​和输出保存到文本文件中.

The shell has a command called "script" which saves input and output to a text file.

使用"bash"作为所有用户的登录shell. bash正在将所有命令写入用户/home
的bash_history
但是至少有一个陷阱. bash_history是用户可写的，可以修改.同样适用于命令脚本".

Use ''bash'' as login shell for all users. bash is writing all commands to bash_history at users /home

But there''s at least one pitfall. bash_history is writable by the user and can be modified. Same applies to command ''script''.

您将需要编写自己的shell，该命令会将所有命令记录到文件中.或者，修改系统上的默认用户外壳程序以执行相同的操作，并确保用户无法切换到其他方法之一.

You would need to write your own shell which logs all commands to a file. Or, modify the default user shell on your system to do the same, and ensure that users are not able to switch to one of the alternatives.
