KDE: sending files to a script from the browser

[Joel Hammer]

Well, my first effort at a swarm script worked, but only for a small number
of files. If files > 10, my system slows down a lot.

So, version 2.

KDE starts up all the scripts with the open with command, but each script
immediately suspends itself with SIGSTOP.  This saves CPU time.

A master script is started or is running in the background, whatever, and
this wakes up each of the slave scripts sequentially by sending them a
SIGCONT signal.

This actually works for a large number of scripts, although KDEinit
starts taking up a lot of CPU time.

KDE is a weak sister, IMHO.

A slave (Comment.scr) script aborts the entire editing session by sending
a SIGUSR1 to the master script (Master.scr), which then sends all the
scripts a kill signal.

I think I could have gotten away without a separate master script by
having each slave script become the master script in turn, but, the
single master script seemed much easier to to.

Who says linux can't be fun and useful?

Now to label all those Hawaiian  photos. This is where my wife comes
in. I sure hope she likes vim.

The MASTER script, Master.scr

#!/bin/bash
abort()
{
rm junkwaiting
ps ax | grep Comment.scr | sed "s/^ *//" | cut -f1 -d " " > junkwaiting
[ -s junkwaiting ] && {
while read i
do
kill -9 $i
echo kill -9 $i
done < junkwaiting
}
}
trap abort SIGUSR1 
j=0
while [ "$j" -le 1 ]
do
	ps ax | grep -v grep | grep vim
  [ $? -eq 0 ] &&   echo "vim is running"  || {
    ps ax | grep Comment.scr  | sed "s/^ *//" | cut -f1 -d" " > junkwaiting
    read i < junkwaiting
    echo $i
		[ -z "$i" ] || kill -SIGCONT $i 
                 }
sleep 2
done

END OF MASTER SCRIPT

The slave script, Comment.scr

rm junk$2
