You only need something like "expand" or "tab.c" if you want to convert each tab to a variable number of spaces depending on column position. If you just want each tab to become a single space, which is what I think your "in other words" says: $ tr '\011' ' ' < input > output If you want each _sequence of one or more tabs and/or spaces_ to become a single space, which is what the example looks like: $ sed 's/[ ^I][ ^I]*/ /g' < input > output (^I represents an actual tab character; in bash I get that by the two-keystroke sequence CtrlV CtrlI but other shells may vary. Dunno offhand if sed would understand the \t or \011 notation.) ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
