Can I execute a system command within in AWK program?

[hongtli]

Thanks a lot in advance!<br><br>I got an idea: when the AWK program scans a report file and finds a data entry that exceeds a threshlod, and I want to send an email to inform someone about this (using mailx command), I wonder if I can do it. if can, how to do it?

cat report ¦ awk ‘$n &gt; threshold {print $0}’ &gt; result<br>if [ -s result ]<br>then<br>cat result ¦ mailx -s &quot;MESSAGE” mail@address<br>else<br>echo “None exceeds threshold”<br>fi<br><br>Notes: - &quot;-s&quot; is the test in korn shell for file exists and is greater than zero. <p>Ged Jones<br><a href=mailto:gedejones@hotmail.com>gedejones@hotmail.com</a><br><a href= > </a><br>

Is there a way to execute unix shell commands from inside an awk program?&nbsp;&nbsp;Thanks in advance.<br><br>&nbsp;~aithosn8

I have found an answer for my own question.&nbsp;&nbsp;To run a system command from inside an awk program simply follow the syntax below where command is the system command being run.<br><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;system(&quot;command&quot<br><br>&nbsp;~aithosn8
