Synopsis

filelock_midwife -help

filelock_midwife [-file filename] program [programargs]

Description

filelock_midwife starts a given program, while creating an artifact of the program's birth. At a later time the filelock_undertaker can examine the artifact to determine whether the program is still running, or whether the program has exited. filelock_midwife accomplishes this by obtaining a file lock on the given artifact file before starting the program.

Warning: filelock_midwife will not work on NFS unless the separate file lock server is running.

Options

-file filename
The filename to use for the artifact file. The file lock.file is the default file used when this option is not specified.
program [programargs]
Forks a process and executes program with programargs as command-line arguments (when specified).

Exit Status

filelock_midwife will exit with a status of 0 (zero) upon success, and non-zero otherwise.
