How about the tr command? When you have an empty line, you really have 2 new-line characters in a row, so you could execute a command like this: $tr -s '\n\n' < file > file_with_no_blank_lines check the tr man page. The man page didn't mention that the single quotes are needed, but they are. Mark -- Psyche-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/psyche-list
