Hello,

I had this script but can't work

# read "input.txt"
open (FILE, 'org.log') or die "$!";
open (NEWFILE, '> joinline.txt') or die "$!";
$line = '';
while (<FILE>) {
chomp($_);
if ($_ ne '') {
$line = $line . "" . $_;
} else {
print "$line\n";
print NEWFILE "$line\n";
$line = '';
}
}
close (FILE);
close (NEWFILE);

uclean

UCLEAN(1)							 Command reference							 UCLEAN(1)

NAME

       uclean - remove redundant files from upstream source packages

SYNOPSIS

       uclean FILE [ NEWFILE... ]

DESCRIPTION

       Uclean is an attempt to automate the "cleanup" procedure that can be needed for some package upstream tarballs. It will try to unpack it,
       remove cruft like CVS directories, .svn directories and forgotten object files. Then it will recreate the tarball, using the highest
       compression ratio. The resulting file is either stored under the same name (the old one is renamed) or as a new file if you specify it as
       the last argument.
