当我在shell脚本中使用exit命令时,脚本将终止终端(提示符)。是否有办法终止一个脚本,然后留在终端?
我的脚本run.sh希望通过直接获取或者从另一个脚本获取来执行。
编辑:
更具体地说,有两个脚本run2.sh as
...
. run.sh
echo "place A"
...
然后运行。sh as
...
exit
...
当我经过它的时候。如果它在run.sh中命中退出代码线,我希望它停止到终端并停留在那里。但是使用出口,整个航站楼会关闭。
PS:我已经尝试使用返回,但回声代码线仍将执行....
是的,你可以用return代替exit。它的主要目的是从shell函数返回,但如果在source-d脚本中使用它,它将从该脚本返回。
如Bash参考手册§4.1“Bourne Shell Builtins”所述:
return [n]
Cause a shell function to exit with the return value n.
If n is not supplied, the return value is the exit status of the
last command executed in the function.
This may also be used to terminate execution of a script being executed
with the . (or source) builtin, returning either n or
the exit status of the last command executed within the script as the exit
status of the script.
Any command associated with the RETURN trap is executed
before execution resumes after the function or script.
The return status is non-zero if return is used outside a function
and not during the execution of a script by . or source.
