I am trying to find any line with the 9th column's number greater than 200, but why the following awk command does not work?

awk '$9 > 200' /tmp/test

2007-09-05 10:13:05.714 640.847 any 1.2.3.4 719 2445 487260 32 6082 199
2007-09-05 10:13:02.686 641.827 any 1.2.3.4 670 2074 411983 13 5135 198
2007-09-05 10:13:07.502 639.151 any 1.2.3.4 625 1995 397378 30 4973 199
2007-09-05 10:13:19.030 627.135 any 1.2.3.4 606 1945 379585 300 4842 195

works just fine under Cygwin's 'gawk', MKS 'awk' and Solaris' awk-s:

$ awk '$9 > 200' fedora.txt
2007-09-05 10:13:19.030 627.135 any 1.2.3.4 606 1945 379585 300 4842 195

What does "does not work" mean?
What exactly happens?
What did you expect to happen?

(That script works for me in the way I think you intended.)
