Hi Eric Blake, Thank for your email. This problem is solved when I used the command 'sort -g -k1,1 t.txt'.
where -k1,1 indicates first field and all characters, you could also use 'sort -g - k1.1,1.8' which represents first field and 1 to 8 characters. I hope this problem is solved for time being. Thank you very much, mallika From: Eric Blake [mailto:[EMAIL PROTECTED] Sent: Thu 8/30/2007 7:32 PM To: Mallika Veeramalai Cc: bug-coreutils@gnu.org Subject: Re: Reg.

I'm not quite sure what question you are asking, so here's the question I will answer: "Why doesn't the sort provided natively with MacOS X 10.4.10 provide the -g option?" In which case, the answer is, this is the wrong list to ask the question on. 'sort -g' is a GNU extension, provided by GNU coreutils, but not required by standards bodies. Therefore, if MacOS ships with their own sort, rather than the GNU coreutils version, then they don't have to support -g; and if you want it to support -g, you should ask on a MacOS support forum. Fortunately, there is no law that says you can't also install GNU coreutils on a MacOS X 10.4.10 system, and put its location first in your PATH, in order to choose the GNU sort instead of the Mac native sort. But keep in mind that using GNU extensions in scripts means your scripts are no longer portable to non-GNU systems, as you discovered. - -- Don't work too hard, make some time for fun as well!
