The convention of having the command shell replace "*" with a list of all matching files in the current folder[1] only in is... well.

I understand how it's useful for really basic core file utilities.

For anything that needs to do recursive directory-searches, though, it really gets in the way and raises the bar for what the user has to know in order to make use of CLI in Linux.

I just now had a long conversation with an advanced bash user[2], and apparently there really is no way to get this information without setting an option in bash before running a command (and then presumably unsetting it afterwards, so as not to break other programs).

Just... why.

[1] ...and *only* the current folder... and only including folders that match the same pattern -- like "*.rb" would include a folder named "foldername.rb", which pretty much never happens

[2] Much thanks to sophia kara for hashing through this with me. I was very grumpy about it.

@woozle 1. What option is this?

2. Globbing is a convenience, but generally *Not Good Programming Practice*.

3. find | read or find | xargs is probably what you want. More specifically:

while find . <args> | read file do; echo ">>> $file <<<"; <processing on file>; done

I like to echo the name of the file(s) found, first, both as a verification of the find command/results, and as a progress indicator.

#1: I've documented my findings -- https://htyp.org/bash/globbing

#2: Hard agree -- especially when there's no way to access the raw information (without making the user jump through extra hoops to provide it).

#3: I'd consider this an "extra hoop".

It seems to me that bash needs to be patched to provide the information in the execution environment. It already provides all kinds of other information of more dubious value, e.g. the format of the command-prompt, so why not this?

@woozle Bash is (at least) two things:

1. An interactive command environment.

2. A scripting tool.

The *benefit* of combining these features is that _what you use daily to interact with the system_ is *also* what you can use _for basic system automation tasks_.

In fact you can segue from one to the other through "shell one-liners" and the like. As a consequence, bash is the one programming tool I know best, _simply from daily familiarity_.

The combination also forces compromises.

@woozle You might want to consider what the options of Doing Things Differently might be:

- You could have _no_ globbing. Running quick shell commands interactively would be ... tedious.

- You could put globbing elsewhere -- have individual commands glob by their own logic. DOS variants did this, with the obvious result that ... different commands glob differently. By globbing *in the shell*, expansion occurs *before the command runs.* Commands see the expansion, not the glob.

@dredmorbius @woozle The Amiga had globbing and command-line parameter handling in the commands rather than the shell and it was uniform and it was beautiful, because they all used the same functions in dos.library.
@notclacke How did scripts handle globs?
@dredmorbius Good question! I think it never came up. AmigaShell scripts have a facility for receiving parameters using the dos.library command-line parser and some rudimentary control flow, but I think at the point where you wanted to do anything beyond simple batch processing you'd switch to ARexx or C.

@clacke
@notclacke @dredmorbius wiki.amigaos.net/wiki/AmigaOS_… doesn't even mention that Shell would have loops, so I don't think you'd be able to do anything useful with an expanded wildcard.
