[SOLVED] playing with variables (need help)

robertjinx · 12-19-2012, 06:10 AM

Hello, I've got a simple variable which will have values similar to this:

VAR1="3270/tty0"
VAR1="3270/tty1"
VAR1="3270/tty3"

and so on. I need to somehow strip it, so I would get only the ending numbers, meaning 0, 1, 3, etc.

So I would need to drop 3270/tty and only end-up with 0, 1, 3. I know is somehow possible, but don't know how.

If anybody knows, help would be appreciated.

Shell parameter expansion is what you're looking for:

Code:

echo ${VAR1##*/tty}
