Thanks for replying to this mail.
Now I need to write a regular expression so that I only get username
from the output of this command.
So I have written like this.
my $usr=`who am i`;
$usr=~ m{(.+)\s$};
print "$usr\n";
But still I am not getting only username.
Please guide.
Regards
Irfan.

No.
You're actually executing the `who` command,which just take the `am i`
as its arguments.
The results are the same:
$ who am i
pyh pts/0 Oct 26 18:48 (116.21.60.xx)
$ who
pyh pts/0 Oct 26 18:48 (116.21.60.xx)
This is `whoami` 's output:
$ whoami
pyh
