'which' isn't a 'bash util' whatever that is (presumably you mean a shell built-in). As you've found out, 'which' is an external program. To find out how the shell thinks about out a command, use the 'type' command... $ type which which is /usr/bin/which $ type type type is a shell builtin $ type foobar bash: type: foobar: not found $ type which which is hashed (/usr/bin/which) In the last, 'hashed' sorta means 'cached' so it doesn't have to search the whole path again to find it. From the posix standard [1]... an implementation may remember its location and need not search for the utility again unless the PATH variable has been the subject of an assignment. If the remembered location fails for a subsequent invocation, the shell shall repeat the search to find the new location for the utility, if any.

Re: bash: which: command not found? + (E: Unable to locate package which? ...)
after reading through all your suggestions and still wondering about
what exactly was the mistake that I had made, I realized that it was a
simple and stupid "type in a rush and let 'the compiler' (sorry!) find
the mistake for you" kind of error: it seemed to have been somehow
blanketed by my "unconscious" that bash utils needed to be declared in
the PATH in order for you to access them. Noticing it and opening
another windows was all it took.

You're delusional. If you need any additional help (beyond what has already been provided) in fixing your "couldn't run cat" problem, please follow these basic guidelines when asking for help: 1) Show us the problem. "I couldn't run cat" is about a 2 out of 10 on the usefulness scale. A much better start would be to *paste* the relevant lines (whole lines) from your terminal session into the email. What you paste should show us your shell prompt, the shell command that you typed, and all of the output you received. For example: unicorn:~$ catt /etc/group bash: catt: command not found 2) Give us basic background about your system. What version of Debian are you running? What, if anything, have you changed which might have an effect on the problem you're experiencing? Since you're having a problem running a standard shell command, things that might fall into this category would include: * I changed my account's shell from ___ to ___. * I edited my ~/.bashrc (or ~/.zshrc or whatever) dot file. * I tried to upgrade from buster to bookworm, and I got errors, but I ignored them until now. 3) Tell us what, if anything, you've already tried. Give us all the additional details you have. * The problem happens in all terminals I've tried -- xterm, rxvt-unicode, gnome-terminal and konsole. * If I type 'zsh' the problem goes away. But I really want it to work in bash too. * I did a 'locate cat' and I can see that it's in /usr/bin, or at least locate thinks it is. Here is the output of 'ls -l /usr/bin/cat'.

I don't understand what this means, and I don't recognize this use of
"multiversing". (At a guess, I'd parse that verb as meaning something
like "splitting into multiple universes", which seems completely
unrelated to this context.)
I also don't see what that has to do with anything else that's in this
message.

Currently, which is (still) provided by the 'debianutils' package.
There's a whole flap about that; the package maintainer doesn't think it
belongs there and doesn't want to keep maintaining it and apparently
wants to declare it deprecated in favor of the (not 100% comparable)
'command -v'. Other people dispute that, to some degree or another, and
there has been *far* more discussion of it than the whole thing would
seem to have deserved.
You can see reference to the bug reports involved in
/usr/share/doc/debianutils/changelog.Debian.gz, at least if you're
running the version that's in testing or newer.
I think the idea is that eventually there will (probably) be multiple
implementations of which provided by multiple packages, and you can
install and use whichever one you want via the Debian alternatives
system. But for the time being, the debianutils version seems to still
be the only one available, at least in testing.

There's one too many '.' characters there, but that shouldn't be the
cause of your issue.

So, did you check what $PATH contains? (e.g. echo $PATH) It seems
likely it's corrupted or missing the right directory (/usr/bin see
below).

Because there's no package called 'which', the which command is
provided by debianutils. Which you could have found by Googling for the
ways to find out the package. For me, the first search result was...
https://superuser.com/questions/10997/find-what-package-a-file-belongs-to-in-ubuntu-debian
[...]
# which bash
/usr/bin/bash
So, $PATH in your root environment is OK. So you could have run
#which which
/usr/bin/which
So it's in /usr/bin and you could have found the package it belongs with using:
#dpkg -S /usr/bin/which
debianutils: /usr/bin/which

If using bash, likely the type command will work.

Sorry. I don't understand what you are saying there. What does mean
"you couldn't run cat"? Your fingers froze while typing? Your keyboard
delivered an electric jolt to you? Help your helpers. Don't tease them
with riddles.

Not every binary is contained in a package called like it.
That's what "apt-file" is for (in the same named package):
tomas@trotzki:~$ apt-file search bin/which
debian-goodies: /usr/bin/which-pkg-broke
debian-goodies: /usr/bin/which-pkg-broke-build
debianutils: /usr/bin/which
emboss: /usr/bin/whichdb
whichman: /usr/bin/whichman
...i provided more of the path ("bin/which") because I'd
otherwise get too many hits.
It seems you're looking for the package "debianutils".
(NB: "apt", not "apt-get" has an interface to "apt-file"
so you can just type "apt search").

This could happen if cat has mode 744 (executable only

which has been deprecated. Use command -v. If you need which -a, you
