From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Request for Opinion - JCL but for Linux?? (lemmy.one)

Any interest in this:

LJL is a job creation language that takes a job file, gathers items mentioned in its various lines and here-documents, and generates a runnable .deck file (short for "deck of cards").

The .deck file is a complex Bash script that creates a log spool and several temporary files in /tmp/. It automatically cleans up scratchable files after the run. The log file contains the output of each step, including any program results.

Any questions about it? Any suggestions?

I manually created a .deck file to compile and run a Fortran program with specific data and to create a .log file of all the output, the Fortran program, and the data. I found it to be picky and somewhat hard. So I thought to myself: With something like JCL, one could take simple JCL-like statements, here documents for the source and data files, and programmatically combine them to make a script like the one I created manually.
