filelock_undertaker

determine whether a process has exited

Synopsis

filelock_undertaker -help

filelock_undertaker [-file
filename] [-block]

Description

filelock_undertaker can examine an artifact file created by filelock_midwife and determine whether the program started by the midwife has exited. It does this by attempting to acquire a file lock.

Be warned that this will not work on NFS unless the separate file lock server is running.

Options

[-block] If the process has not exited, block until it does.
[-file/SPAN>filename] The name of the artifact file. created by filelock_midwife. The file lock.file is the default file used when this option is not specified.

Exit Status

filelock_undertaker will exit with a status of 0 (zero) if the monitored process has exited, with a status of 1 (one) if the monitored process has definitely not exited, with a status of 2 if it is uncertain whether the process has exited (this is generally due to a failure by the filelock_midwife), or with any other value for program failure.
