How execute a command in a separate directory without changing current working directory in Bash

The following example shows how to move to a directory before executing a command and then automatically return back to the old diretory. This effectively runs the command with current directory as a different directory.

[neo@techpulp ~]# pwd
/home/neo
[neo@techpulp ~]# (cd /; ls)
bin  boot dev  etc  home  lib  lost+found  media  mnt opt  proc  root  sbin  selinux  srv  sys  tmp  usr  var
[neo@techpulp ~]# pwd
/home/neo
[neo@techpulp ~]#

As you can see, the commands are grouped in parenthesis so that the current directory remains same after running the commands.
