I'm getting nowhere trying to parse out IP addresses from strings of
this form in /bin/sh, which have been awk'd out of 'tail named.run':
addr='195.68.176.4#1440:'
addr='195.68.176.4#16811:'
addr='195.68.176.4#276:'
sh(1) in hand, I've tried:
ip=${addr:%#*}
ip=${addr:%%#*}
ip=${addr:%[#]*}
ip=${addr:%%[#]*}
but all of these report './testbit: 7: Syntax error: Bad substitution'
How can I split these strings to exclude the '#' and all beyond,
preferably using sh syntax, at least without resorting to perl?
Please cc me as I'm only subscribed to the digest.
TIA, Ian
