Remove a character from the end of a variable

Question

Bash auto completion appends a / at the end of a directory name. How I can strip this off from a positional parameter?

#!/bin/sh

target=$1

function backup()         


        

Answer 1

Be careful, bash3 added perl-similar regex to bash. The guide mentioned covers this as well as the official guide at GNU , but not all references do.

What did I do?

Substitute 2.19/* to be 2.19.

Solution

VER="2.19/foo-bar"
NEWVER=${VER%/*}
