in reply to Re^6: find common data in multiple files
in thread find common data in multiple files
"Do all your 25 filenames start pm_1206312_in and if not what are they like ?"
I think poj's original question was intended to provoke thought. If the glob pattern you're using is 'pm_1206312_in*' no file with a pattern '4_os_*.txt' will be matched. Please see the documentation for glob and links therefrom for information on constructing glob filename patterns.
