.SH NAME
testlock \- lock a file and run a command with the lock held
.SH SYNOPSIS
testlock [-v] [-t timeout] [-s] [-r exittcode] filename command args ...
.SH DESCRIPTION
.PP
Testlock will acquire a file lock and then execute a command while the lock is held.
If no timeout is provided, testlock will wait indefinitely until the file can be locked,
and then execute the command.
If a timeout is given, it will stop waiting after that many seconds have passed.
.SS Options
.IP -t
Abort if the lock cannot be acquired after
.I timeout
seconds.
If
.I timeout
is 0, the lock will be totally non-blocking.
.IP -s
Silently ignore errors with locking.
(Other errors will still be reported.)
.IP -r exitcode
If the lock cannot be acquired, use this exit code instead of the default exit code of 99.
