How to get current working directory before changing it

Question

I have this function

snip-git(){
    cd  ${snippetdir}
    git add .
    git commit -m "."
    git push -u
}

When git finishes pushing the changes, I want to get back to the directory I was when I called snip-git.

I tried this

snip-git(){
    cwd=$(pwd)
    cd  ${snippetdir}
    ...
    cd cwd
}

But it ends up reading the ned directory rather than the old one

The easiest way is making your works in a subshell only:

snip-git() (
    cd  -- "$snippetdir"
    git add .
    git commit -m "."
    git push -u
)

There're some thing you want to fix in your function:

That's not working! I'm on root directory (but I could be anywhere), I run `snip-git' at the end of push, I'm not redirected to the root – relidon Mar 22 '16 at 10:28
@relidon: Did you change the `snip-git` definition to use `(...)` instead of `{ ... }`? – cuonglm Mar 22 '16 at 10:29
Now I did :) and it works. What's the difference in `( )` and `{ }`. Thanks @cuonglm – relidon Mar 22 '16 at 10:35
@relidon: As I said in my answer, `( )` ran your commands in subshell, after your command done, the environment was restored. – cuonglm Mar 22 '16 at 10:36
