Folks: have a look at this FreshPorts shell script and let me know if
there is a better way to do this.
This script waits for a file to arrive in a directory, then runs a scipt
to process it. It's part of FreshPorts. the procmail script spools the
incoming cvs-all message to a temporary location, then moves it to the
incoming directory.
The lockfile is an attempt to make the script single-entry (only one
instance at a time). If fails because the only way to exit the script is
to terminate it...
At present, this script runs within a screen session (that's the easiest
way to control it). This script is sort of like a daemon, and I'm tempted
to replace it with one. If it was a daemon, I'm sure that would be much
easier.
#!/bin/sh
LOCKFILE=${HOME}/msgs/processing.lock
MSGSDIR=${HOME}/msgs/FreeBSD/incoming
lockfile -r 0 $LOCKFILE
RESULT=$?
#echo result='$RESULT'
if [ $RESULT = 0 ]
then
cd ${MSGSDIR}
while .
do
FILECOUNT=`ls | wc -l`
if [ $FILECOUNT -ne 0 ]
then
ls | xargs -n 1 $HOME/scripts/test-freebsd-cvs.sh
fi
sleep 1
done
rm -rf ${LOCKFILE}
fi
