zsh is a really odd choice. It's a hodgepodge of features from bourne and csh, with its own special extensions. It's not comparable and not compatible.

I don't know why they needed a shell to be...

That's all it means. The culture is not UNIX culture, it's BSD and GNU. The entire "classic UNIX approach of free and open" was anti-UNIX backlash! A little history is needed to understand why.

You made your executable correctly. It should have worked. It did work -- except, not in your window manager.

There could have been -- and may still be -- issues with your window manager,...

These files are used on login. sudo bash is not a login.

Environment variables are external memory designed to be shared. Functions are part of a shell's internals and are not. For sudo bash to...

In the literal, legal sense, UNIX means you had your operating system tested and certified as UNIX-compliant. Apple did this, and Linux hasn't (and perhaps can't, except for a tiny subset of...

Well that's not going to work. You're just printing the statements to the screen and not giving anything to sshpass at all.

Does your script change the variable IFS? Strings are supposed to...

I won't know the issue until it works. Nonprinting characters are nonprinting, invisible to copy-paste. If there were nonprinting characters in your array you might not see them. Did you try my...

What's your operating system? That's important for how ps behaves.

It can't match ID and name on numbers because that's ambiguous. There could be several "correct" entries, which isn't supposed...

No reason * shouldn't expand, perhaps you ended up with nonprinting characters like carriage returns in your array or some such. If the commands work when pasted, that's what I'd bet.

We get asked how to do date math in AIX so often I made a perl script for it (https://www.unix.com/unix-for-beginners-questions-and-answers/239167-general-purpose-date-script.html). It's a...

A level of quoting disappears (because your local shell interprets it first) when you put code over ssh / sshpass. You need to quote some of your quoting.

If your values will never contain spaces, you can "pass" arrays as strings "val1 val2 val3" and split them back inside the function, like this:

#!/bin/ksh

set -A filelist val1 val2 val3

To repeat: It's not a setting, it's hardcoded. Changing it won't change programs. You'd just make it lie.

It might be possible to build a custom ksh with a higher setting but that sounds far...

It's a hardcoded limit, not something trivially changed. Even if you coerce getconf into changing, it won't be reflected in programs. But I suspect you're using a crusty old pdksh/ksh88, newer ksh...

Sorry, my morning coffee hadn't kicked in.

Your chroot commands get things ready for a chroot, but don't actually run chroot, so nothing ends up happening inside the chroot.

If you call chroot...

This is a rather roundabout way of sending files! sshpass executing sshpass executing scp. Isn't there a better way?
