Temporarily change current working directory in bash to run a command [duplicate]

问题

This question already has answers here:

How do I run a program with a different working directory from current, from Linux shell? (11 answers)

Closed 5 years ago.

I know I can use cd command to change my working directory in bash.

But if I do this command:

cd SOME_PATH && run_some_command

Then the working directory will be changed permanently. Is there some way to change the working directory just temporarily like this?

PWD=SOME_PATH run_some_command

回答1:

You can run the cd and the executable in a subshell by enclosing the command line in a pair of parentheses:

(cd SOME_PATH && exec_some_command)

Demo:

$ pwd
/home/abhijit
$ (cd /tmp && pwd)  # directory changed in the subshell
/tmp 
$ pwd               # parent shell's pwd is still the same
/home/abhijit

回答2:

bash has a builtin

pushd SOME_PATH
run_stuff
...
...
popd 

回答3:

Something like this should work:

sh -c 'cd /tmp && exec pwd'
