It is not mandatory that you install it - Yes, there are other choices already. But in the beginning, Unix only had C and Assembly why didn't we just stick with those?

More Detail::: What SUBMIT Does with Each LJL Statement:

For every statement, SUBMIT generates corresponding commands in the .deck file. Below is a step-by-step breakdown:

One //jo line, as many /dd lines as are required, and as many //ex as are required

//jo sumjob [email protected] log=print class=a

Generates a deck command to invoke ifclass a, which checks if the job's class allows execution at run time.
Generates a deck command to Log "sumjob is starting" to /var/log/JCL/ with a timestamp.
Generates a deck command to create /tmp/sumjob
Generates a deck command to initializes /tmp/sumjob/jobname.log with a formatted header (e.g., via figlet sumjob).

Job Classes: A = Runs as soon as submitted B = Runs only if load is low enough C = Runs in Off-Hours

//dd alias source(here|file=pathandfilename|new) disp(keep|scratch)

Note the disp (disposition) if keep the put the file in /home/user/.lcl/jobname as whatever the alias is if the disp(scratch) then the file will go into the /tmp/jobname directory as named by the alias.
Generate deck commands to

-- if source is here: copy lines from lcl up to '/*' to the deck file as a here document if source is a file: add commands to copy the file into a working directory either in user's home or in the tmp directory under the alias. //dd users source(file=/etc/passwd) disp(keep) ==> copy /etc/passwd to /home/user/.ljl/users

//ex somecommand --options < alias

-Generate doc commands to execute the program as specified and save the output to the logfile In this case echo (somecommand --options < aliasproperlyexpanded ) > logfile

The deck file now forms a fully functional batch file to do the specified computation.

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.

Debian/KDE because I like the way I can customize (1 panel on the left with everything) No features removed just as one gets used to them. (looking at you gnome) No breaking changes to the desktop gadget api every update (you gnome again) Nice big repo.

I don't bend my values for entertainment. I pick my OS for privacy and freedom first. If a game won't run on it, that game doesn't run in my life.

I used chatGPT to work up a backup program that tracked rsync backups as I wanted and could report which backups needed to be run and which ones should be started fresh because too many rsync runs from my home dir to the target dir. It's call Loci, and it's on codeberg.

I think I read this is how HP supplies their "no OS" machines - a very thin Linux with a VM running the FreeDOS fullscreen.

"UEFI does have a legacy compatibility layer" And this is how one may have a "system firmware" that allows both. Could DOS be made UEFI compatible maybe by loading a .sys driver or maybe by replacing io.sys with one that made use of UEFI?

My system came with Python3 installed. Debian 12.

Looks like a line by line translation from the python. Will you use it to backup your home directory?

Actually, I do have a quite usable FreeDOS running in DOSBox on my Linux machine, but it's not quite the same as running DOS / FreeDOS on the metal. Getting floppies to work as seamlessly as they do on a machine meant for DOS for example.

Linux for example will boot easily under both UEFI and BIOS - but I suppose that is because Linux does not ask anything of either once it is running.

@[email protected] I see what you're asking. You’re wondering if, instead of storing a duplicate file when another backup set already contains it, I could use a hardlink to point to the file already stored in that other set?

I have a system where I create a backup set for each day of the week. When I do a backup for that day, I update the set, or if it’s out of date, I replace it entirely with a fresh backup image (After 7 backups to that set). But if the backup sets became inter-dependent, removing or updating one set could lead to problems with others that rely on files in the first set.

Does that make sense? I am asking because I am not familiar with the utilities you mentioned and may be taking your post wrong.

Especially one that lets you know how long it's been since you took time to run a backup, keeps track of which set of backups could be updated, and which should be refreshed, and keeps a log file up to date and in .csv format so you can mess with it in a spreadsheet?

That's ok Like any landing you can walk away from. Any code that runs to spec is good, much could be better.
