From: gopikrishnan.gunasekaran@gmail.com on 11 Feb 2006 05:44 Hi, The scenario is the awk command should check the second field of the output, if it is greater than 80 it should trigger an automatic email to me in this address, Help me to do this Regards, Gopi Krishnan

Hard to say. He also says to check the second field of "the output" whereas we've both provided solutions for the second field of the input, and using awk like this is obviously not a great way to just send email if you have one line with a second field with value greater than 80. It's hard to say what the OPs really trying to do.... Ed.

I may do it separately otherwise.. awk '$2>80 { print "Some notification"}' | mail -s"length exceeds 80" you(a)addr Xicheng > Hard to say.

With the pipe command within awk there won't be any mail sent if nothing matches, while in your code an empty mail will be created. Janis |
