I have a BASH script that allows a user to specify a jobname. Right now we except everything. We feed this jobname into another executable that can only accept the following formats:

job_name, jobname, job-name, job_name1, job-name1, jobname1, job_name[1-5] job-name[1-5] or jobname[1-5] or other permutations that are alphanumeric (case sensitive) and [, ], _, -

I'm looking for way to trap the name and reject anything that doesn't follow that format. Started trying to use the regex with if statement but the [] seem to be throwing me for a loop.

if [[ $1 =~ [']_-['] ]]; then
   echo "I have the Square Braces"
fi
