I am trying to create an apple automator application that will rename a group of files by removing all text before and including a hyphen ( - ) that will post an error if trying to rename a file with no hyphen.
input is 001-10312233_033
output is 10312233_033
Then if ran again on the same file (10312233_033) would produce an error or warning as there is no hyphen.
Any ideas what script in automator will make this happen?
