Top Forums Shell Programming and Scripting Waiting for an arbitrary background process (limiting number of jobs running) Post 302390812 by p.f.moore on Friday 29th of January 2010 04:23:56 AM

Thanks, that's an approach I hadn't thought of. One thing it doesn't allow me to do is to report progress - something I'd thought of adding to my original approach was to add a "printf '.'" whenever I started a new decompress. But that's just a nice-to-have - your suggestion gets the job done.

I'd still be interested in any other possibilities that anyone can suggest - this is my first venture into anything more complicated than very basic scripts, and I'm learning a lot I didn't know!

Thanks,
Paul.

NAME
proto - prototype job file for at SYNOPSIS
DESCRIPTION
When a job is submitted to or the job is constructed as a POSIX shell script (see at(1)). The job file is created in as follows: o creates a header describing the job as an job or a job. jobs submitted to all queues other than queue are listed as jobs. The header is: for an job, or for a job. o A set of POSIX shell commands is added to make the environment (see environ(5)) for the job the same as the current environment. o then copies text from the prototype file to the job file, except for special variables that are replaced by other text: Replaced by the current working directory. Replaced by the current file size limit (see ulimit(2)). Replaced by the current umask (see umask(2)). Replaced by the time at which the job should be run, expressed as seconds since January 1, 1970, 00:00 Coordinated Universal Time, preceded by a colon. Replaced by text read by from the standard input (that is, the commands provided to to be run in the job). o When a job is submitted to queue queue, uses the file as the prototype file if it exists. Otherwise, it uses the file EXAMPLES
The following file creates commands to change the current directory, file size limit, and umask in the job to their respective values as they existed when was originally run. These commands are inserted before the commands in the job: SEE ALSO
