Absent a problem description, there's no way to tell whether that does what the OP wants; does he want to treat the last word containing a period as fn.fext, or the fourth word? Does he want to allow multiple periods in the name, e.g., foo.bar.text? I could write a regex for any of these, but not without knowing which, if any, of them is correct.

The simple answer to the elliptically stated problem is: MyVal = 'word3' A more general solution, using regex is: 556 $ echo 'word1 word2 9.12 word3.ext' | sed 's/.* \([^.]*\).*/\1/' word3 557 $ This finds the last substring in the subject preceded by a space and followed by a period. Full disclosure, for Tony to gloat: o It's easier to code than to review. o I got it right on the third try. o I haven't fuzz tested. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
