May be a bit off topic, but I don't know any sh scripting lists that I'm =
subscribed to... :)

If I run the script from shell / console, it runs without a problem....  =
Running it via cron, I get: [: 6: unexpected operator

The script:
#!/bin/sh
HOSTNAME=3D`/usr/bin/uname -n`
SIZE=3D`/usr/bin/du /var/log/MYAPP/|/usr/bin/cut -c 1-7`
ROTATE=3D"1024000"
if [ -e /tmp/.rotate ]; then
  return 1
else
  touch /tmp/.rotate
  if [ $SIZE -ge $ROTATE ]; then
    /bin/mkdir -p /usr/local/backup/var/logs
    cd /usr/local/backup/var/logs
    for X in `ls /var/log/MYAPP/`; do
      rm -f $X.9.tgz
      mv $X.8.tgz $X.9.tgz
      mv $X.7.tgz $X.8.tgz
      mv $X.6.tgz $X.7.tgz
      mv $X.5.tgz $X.6.tgz
      mv $X.4.tgz $X.5.tgz
      mv $X.3.tgz $X.4.tgz
      mv $X.2.tgz $X.3.tgz
      mv $X.1.tgz $X.2.tgz
      /usr/bin/tar -czf $X.1.tgz /var/log/MYAPP/$X > /dev/null
      /bin/cat /dev/null > /var/log/MYAPP/$X
    done
    /bin/echo "/var/log/MYAPP Rotated on $HOSTNAME" | /usr/bin/mail -s =
"MYAPP Log Rotation" my@somwhere
  fi
  /bin/rm /tmp/.rotate
fi

No, unfortunately, I MUST script this, I cannot use logrotate / =
newsyslog / name your fav log rotation tool, as they all destroy active =
file handles on the log file.  cating /dev/null to the log is a good way =
to clean the log, whilst allowing a MULTITUDE of applicating writing to =
the file, to keep their file handles in tact....=20

Anyone that can give me a indication of what is going haywire in the =
script?

Thank you kindly,
Chris.
