Is it best to wright menu driven script all in one file of link it to different scripts
If linking how do that ?

Is there away when a script exits to leave you in the directory the script it self was last in b4 exit instead of returning you back to to dir you where in when you started script.
ie..
start script in \home
script runs and change dir a few time finishing in \home\whatever
script exits and your shell returns prompt back in \home
how do get prompt back so you are still in \home\whatever

Is there away to kill processes without the pid No
ie process name
