rememberPWD

saves PWD to disk and sets previous PWD when starting a new BASH shell

The intended use is for systems that have users su - / sudo su - to use the root account (mainly Debian distros).

This script will cd the root/other user into their previous PWD. For example,

Terminal 1

1. user1@Linux:~$
2. user1@Linux:~$ sudo su - otherUser2
3. otherUser2@Linux:~$
4. otherUser2@Linux:~$ cd /var/log/
5. otherUser2@Linux:/var/log$

Terminal 2 (or TAB)

1. user1@Linux:~$
2. user1@Linux:~$ sudo su - otherUser2
3. otherUser2@Linux:/var/log$ <--- user is in same directory as before

My script adds this to the end of your .bashrc:

# save PWD to disk
function cd {
 builtin cd "$@"
 echo $PWD > ~/.previousPWD
}
cd "`cat ~/.previousPWD`"
