Run script before Bash exits
提问by Facundo Casco
I'd like to run a script every time I close a Bash session.
我想每次关闭 Bash 会话时都运行一个脚本。
I use XFCE and Terminal 0.4.5 (Xfce Terminal Emulator), I would like to run a script every time I close a tab in Terminal including the last one (when I close Terminal).
我使用 XFCE 和终端 0.4.5（Xfce 终端模拟器），我想每次关闭终端中的一个选项卡时都运行一个脚本，包括最后一个（当我关闭终端时）。
Something like .bashrc but running at the end of every session.
类似于 .bashrc 但在每个会话结束时运行的东西。
.bash_logout doesn't work
.bash_logout 不起作用

You use trap(see man bash):
您使用trap（参见man bash）：
trap /u1/myuser/on_exit_script.sh EXIT
The command can be added to your .profile/.login
该命令可以添加到您的 .profile/.login
This works whether you exit the shell normally (e.g. via exitcommand) or simply kill the terminal window/tab, since the shell gets the EXITsignal either way - I just tested by exiting my putty window.
无论您是正常退出外壳程序（例如通过exit命令）还是简单地终止终端窗口/选项卡，这都有效，因为外壳程序以EXIT任何方式获取信号 - 我只是通过退出我的腻子窗口进行了测试。

My answer is similar to DVK's answerbut you have to use a command or function, not a file.
我的回答类似于DVK 的回答，但您必须使用命令或函数，而不是文件。
$ man bash
[...]
trap [-lp] [[arg] sigspec ...]
The command arg is to be read and executed when the shell
receives signal(s) sigspec.
[...]
If a sigspec is EXIT (0) the command arg is executed on
exit from the shell.
So, you can add to your .bashrcsomething like the following code:
因此，您可以添加.bashrc类似以下代码的内容：
finish() {
# Your code here
}
trap finish EXIT

Write you script in "~/.bash_logout". It executed by bash(1) when login shell exits.
在“~/.bash_logout”中编写脚本。它在登录 shell 退出时由 bash(1) 执行。

If you close your session with "exit", might be able to something like
alias endbash="./runscript;exit"and just exit by entering endbash. I'm not entirely sure this works, as I'm running windows at the moment.
如果你用“exit”关闭你的会话，也许可以
alias endbash="./runscript;exit"通过输入 endbash 来退出。我不完全确定这是否有效，因为我目前正在运行 Windows。
