Hi Mark, It may be more useful to run the file through sed(1). The newlines aren't deleted by sed: $ echo '^Fhello^F' | sed -e 's/[^[:print:]]*//' | hd 00000000 68 65 6c 6c 6f 06 0a |hello..| 00000007 $ > I also tried > > cat f | sed "s/[^:print:]//g" > > but it didn't remove the characters. The matching pattern is wrong. You need `[^[:print:]]'. The character class of printable characters is `[:print:]', and you can negate the pattern with `[^xxxx]' where `xxxx' is the character class; hence the extra pair of brackets in `[^[:print:]]'. _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
