get a bash's cwd

Question

If I open up 2 terminals in Ubuntu, via ps u I can see 2 bash's pid.

My problem is from one terminal, how can I know the bash's cwd in the other terminal?

Answer 1

The pwdx command prints the current working directory of each given process ID.

Example from Solaris (believe Ubuntu also has the command):-

$ cd /tmp
$ pwdx $$
22281:  /tmp

Answer 2

You can check

/proc/<pid>/cwd
