how about instead of one script, running 8 scripts from cron, each has
its own lock file:
------------------------------------
#!/bin/sh
#script no.1
LOCKFILE="$HOME/lockfiles/lock_1"
if [ -f $LOCKFILE ]; then
exit 1
else
echo "green light .."
fi
date -u > $LOCKFILE
do something
rm $LOCKFILE
------------------------------------
