If you mean just a space character (this can be done with a regex, but index() should be faster): perl -n -i -e 'print unless 0 == index($_, " ")' FILE If you want to check space characters as Perl knows them (space, tab) use the \S regex class (non-whitespace): perl -n -i -e 'print if m/^\S/' FILE This will edit the file in place. You can make a backup with -i.bak instead of -i; read "perldoc perlrun" for more details. Ted -- Psyche-list mailing list Psyche-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/psyche-list
