Operating Systems Linux Ubuntu How to lock a file through UNIX KSH shell script? Post 302909341 by rbatte1 on Wednesday 16th of July 2014 08:04:18 AM

If they are both doing the same thing, then are they really two scripts? If this is a common function that they would both do, then perhaps it would be better to break that out into a separate function and organise your scheduler a little differently.

If you have Job1 & Job2 currently running in parallel, consider having Job0 to do the common renaming work and then make the remainder of Job1 & Job2 as a dependency on Job0 completing. I suppose it depends on your scheduler.

If it's cron, then it's a little tricky. Commercial schedulers should provide this job dependency control. if you are stuck with cron then consider using some sort of a file to flag that Job0 has completed and have Job1 & Job2 wait for it to appear.

As hicksd8 requests, Please post the script.
As CarloM asks though, what do you really need to achieve?

uudemon(4)						     Kernel Interfaces Manual							uudemon(4)

NAME
uudemon.admin, uudemon.cleanu, uudemon.hour, uudemon.poll - Administrative shell scripts for polling remote systems, cleaning up spool directories, reporting status to the system administrator, and routine invocations of the uuxqt and uusched daemons SYNOPSIS
These shell scripts reside in the following directory: /usr/lib/uucp DESCRIPTION
All the scripts can be run from the command line or can be run automatically by the cron daemon. To automatically run the scripts, remove the comment character (#) from the beginning of the relevant line in the /var/spool/cron/crontabs/uucp file. This script reports status to the system administrator. It issues the uustat command to find out the status of uucp jobs. It mails the results to the uucp login ID. The script may be modified to send mail to any login ID such as the uucp administrative login ID (uucpa) or root. This script cleans up the /var/spool/uucp and /var/spool/uucppublic directories by running the uucleanup command. The uucleanup com- mand is run with the following parameters: -C7, -D7, X2, -o2, -W1. This script runs the uusched and uuxqt daemons in the background. This script polls the systems listed in the /usr/lib/uucp/Poll file. The uudemon.poll script should be scheduled before the uudemon.hour script. This allows uudemon.poll to create any command files before cron runs the uudemon.hour script. FILES
Contains the uudemon.admin, uudemon.cleanu, uudemon.hour and uudemon.poll files. Contains the uucp file. RELATED INFORMATION
Commands: cron(8), uucleanup(8), uusched(8), uuxqt(1) Files: /usr/lib/uucp delim off uudemon(4)
