Hi All, I'm not sure if this is the appropriate forum, please point me to the correct one if it's not.
I'm playing around with regular expressions and I want to achieve the following. I spoke to a Unix geek but he didn't really understand what I was asking. Given the following sample data, I want discover only the first occurrence of any string which matches my regexp. QQQQABCDEFGNOPQRXXXPPPPABCDEFGNOPQRYYYOOOOABCDEFGNOPQRZZZ QQQQABCDEFGNOPQRXXXPPPPABCDEFGNOPQRYYYOOOOABCDEFGNOPQRZZZ QQQQABCDEFGNOPQRXXXPPPPABCDEFGNOPQRYYYOOOOABCDEFGNOPQRZZZ QQQQABCDEFGNOPQRXXXPPPPABCDEFGNOPQRYYYOOOOABCDEFGNOPQRZZZ QQQQABCDEFGNOPQRXXXPPPPABCDEFGNOPQRYYYOOOOABCDEFGNOPQRZZZ QQQQABCDEFGNOPQRXXXPPPPABCDEFGNOPQRYYYOOOOABCDEFGNOPQRZZZ I tried: awk 'sub(/CD.*QR/,"junkt")' fxdata in an attempt to change QQQQABCDEFGNOPQRXXX to QQQQABjunktXXX but instead, it takes the final occurrence of QR, and returns QQQQABjunktZZZ. Notice the ZZZ on the end instead of XXX. This is being driven from a REXX exec in ISPF, if any of the above is not clear, I will try to explain further. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: INFO IBM-MAIN
