delayed-shutdown ---------------- Initscript that delays the shutdown procedure as long as a predefined lockfile (no-shutdown lockfile) exists. The no-shutdown lockfile should be set whenever a running process, for instance a backup script, should not be interrupted by a system shutdown or reboot. When started, this script has no impact on system performance. Manual Installation: As user 'root' follow the instructions to install the file in your initscripts directory: cp delayed-shutdown /etc/init.d/ chmod +x /etc/init.d/delayed-shutdown For RedHat and relatives run: chkconfig --add delayed-shutdown For Debian and relatives run: update-rc.d delayed-shutdown defaults Manual De-installation: If for any reason you need to remove 'delayed-shutdown' from your system do the following: For RedHat and relatives run: chkconfig --del delayed-shutdown For Debian and relatives run: update-rc.d -f delayed-shutdown remove Delete the initscript: rm /etc/init.d/delayed-shutdown Usage: In order to delay the shutdown process until your software finishes its operation, you should create the no-shutdown lock file: /var/lock/noshutdown.lock Then let your software do its job and, when finished, delete the no-shutdown lock file. In case of a script that would be: lockfile /var/lock/noshutdown.lock ... [script is working] ... rm -f /var/lock/noshutdown.lock See the included example script 'test.sh'.
