IMHO, this is perfectly fine. I would have done a few things differently

not source ~/.profile, this script inheirits your enviornment
use variables for the files
not save the results in...

Have you tried something like:
echo kill `ps -ef |grep test.sh| grep -v grep`to see what arguments you are passing to kill.
Or even sh -x badscript?

If I would have to guess ... you are running...

Simply:
ls Projects/S*/MP(assuming there is only S1, S2, ... S20 in Projects)

If there are others, then:
ls Projects/S{{,1}{1,2,3,4,5,6,7,8,9},{1,2}0}/MP(assuming bash or csh)
or even:
ls...

I have been looking at your problem for a while now -- and I have no idea what you are trying to accomplish. Can you please explain? And what function is "sed" providing?

Some hints:


popen (https://www.unix.com/man-page/linux/3/popen/) is not "open a pipe", it is more "open a process"
Use opendir (https://www.unix.com/man-page/Linux/3/opendir/)(3) to open a...

echo '<CTRL-C> has been trapped'
read -p 'Enter to exit: ' line
exit 1
}

while true; do

done

Here is my results:

The reason you are not getting what you expect is that xargs is re-invoking tar every time the command line fills. cpio could be used, or you could use the "-T" option of tar:
find ./ -type f -mtime...

If you take a moment to look at the gzip manual page, the -9 option (aka --best) is for maximum compression.

I assume there is much more to your perl script than the few lines you provided, but going with what you have:

#!/usr/local/bin/perl -w

use Env;

$ENV{NOLOG_qsub} = "";

Apologies for a bad cut-n-paste:

{ C2[$1] += $2; C3[$1] += $3; }
END { for (x in C2) printf "%s\t%d\t%d\n", x, C2[x], C3[x]; }

Here you go:
$, = ' ';
$\ = "\n";

$_ = <>;
my @R = split;

while (<>) {
my @N = split;
if ($P[2] == $R[0] && $P[3] == $R[1]) { @N[0..1] = @R[0..1]; }
@R = @N;
}

print @R;

The awk script:{ l[NR] = $1; n[$1]++; s[$1] += $2; }

Sometimes you get caught up with the tool you are using, when you should look at all your tools.

I've run into this issue when I wrote an rsync script, in which I had to eval the command to get things to work properly, as in:

Your ftp client displays icons, not vsftpd.

For folder sizes -- are you referring to the sum of the sizes of the files contained in a folder? Or the size of the directory itself?
