[ale] Question about awk

[Chuck Payne]

Guys,


Another simple question. I am looking into my mail logs, I just like
to get the ip that is between []

athedsl-4487021.home.otenet.gr[94.71.67.117]:
unknown[187.78.66.100]:
unknown[192.168.105.11]:
c-98-224-185-217.hsd1.mi.comcast.net[98.224.185.217]:
athedsl-333802.home.otenet.gr[85.72.159.136]:
athedsl-333802.home.otenet.gr[85.72.159.136]:
pool-151-202-63-204.ny325.east.verizon.net[151.202.63.204]:
ppp-124-122-183-185.revip2.asianet.co.th[124.122.183.185]:
unknown[62.68.49.34]:


Here my search string...

grep 'Recipient address rejected' mail.log | awk '{ print $10 }'


I have tried to use sed to remove [] hoping that it would every before
and after the [] 's, but it ugly.
