Comment: Hello, I'm trying find a way to check if a variable starts with forward slash "/".
Whoever, nothing that I have tried seems to work. For example, I want to perform the following check on my "out_dir" variable. But it fails the check if [ $out_dir != /* ]
then
echo Error! - Invalid directory specified
echo Script will exit - please run it again
exit
fi Any assistance would be great. Jens

.... If your shell is bash (maybe also ksh?): if [[ ${out_dir:0:1} != "/" ]]
then
