cut lines in a file.
Hi Everyone,
I have a file a.txt, inside is
Mon Jul 20 00:05:07 2009 12
Mon Jul 20 00:05:08 2009 1

The output should be a.txt, inside is
00:05:07 12
00:05:08 1

My method is
Code:
`cat a.txt | cut -f4,6 -d' ' > a.txt.tmp;mv -rf a.txt.tmp a.txt`;

Is any good way to do this? like perl directly or awk.

Thanks
