hi,

The following can be accomplised using Perl script also

[code]
open(i,"<$filein") || die "Can't open $!\n ";
while (!eof(i)) {
$line = <i>;
push @temp, $line;
}
close(i);

foreach $line(@temp) {
$line =~ s/\s+$//o;
}
[\code]

Thanks,
Raj

In Python, if you have it:

>>> for lines in open("yourfile.txt"):
>>>      print  lines.strip()
