Please post a sample of the format of a directory listing of these files which makes it clear what the time and date format looks like and makes it clear whether there are subdirectories under the lock directory:

I've been bitten by using a lock or pid file to prevent multiple instances of a script. A user typed kill -9, and the pid file didn't go away. You can't trap -9. So when he tried to restart, it said "already running", and I got trouble report. Argh.
So here's what we came up with:

OK, so I just messed myself up. Thinking the /var/opt/ignite/data/INDEX files was static, I manually edited the file and added 2 more OS's to it. During an Install it only showed the first OS (started with 11.31, 3 versions then added a 11.23, and a 11.11 stanza's).
The 11.23 and 11.11 never... (2 Replies)

shlock
SHLOCK(1) General Commands Manual SHLOCK(1)NAME
shlock - create lock files for use in shell scripts
SYNOPSIS
shlock -p pid -f name [ -b ] [ -u ] [ -c ]
DESCRIPTION
Shlock tries to create a lock file named name and write the process ID pid into it. If the file already exists, shlock will read the
process ID from the file and test to see if the process is currently running. If the process exists, then the file will not be created.
Shlock exits with a zero status if it was able to create the lock file, or non-zero if the file refers to currently-active process.
OPTIONS -b Process IDs are normally read and written in ASCII. If the ``-b'' flag is used, then they will be written as a binary int. For
compatibility with other systems, the ``-u'' flag is accepted as a synonym for ``-b'' since binary locks are used by many UUCP pack-
ages.
-c If the ``-c'' flag is used, then shlock will not create a lock file, but will instead use the file to see if the lock is held by
another program. If the lock is valid, the program will exit with a non-zero status; if the lock is not valid (i.e., invoking
shlock without the flag would have succeeded), then the program will exit with a zero status.
EXAMPLES
The following example shows how shlock would be used within a shell script:
LOCK=/var/run/innd/LOCK.send
trap 'rm -f ${LOCK} ; exit 1' 1 2 3 15
if shlock -p $$ -f ${LOCK} ; then
# Do appropriate work
else
echo Locked by `cat ${LOCK}`
fi
