Simplest solution that worked when upgrading to Big Sur. A clean install may not require the solution below. There is inconsistency with the way CLT is upgraded to 12.2.
sudo rm -rf /Library/Developer/CommandLineTools
sudo xcode-select --install
Worked with the following versions (post-install)
❯ /usr/bin/xcodebuild -version

You can use file FILENAME to determine the type of data in a file.
$ file image.jpg text.jpg pdf.jpg
image.jpg: JPEG image data
text.jpg: ASCII text
pdf.jpg: PDF document, version 1.4
So, file *.jpg | grep -v JPEG should give a list of all non-JPEGs with the ".jpg" extension
Also, assuming there are PDFs you can rename them in one go
find . -...

The problem seems to be that you're using git ontop of iCloud Drive. I.e. the problem is not with Time Machine and backups at all - it is instead that you have chosen to store your ~/Documents/ folder in iCloud Drive, which is not compatible with programs such as git.
The issue is that iCloud Drive treats each file as an individual and independent file, ...

Do not parse/interpret the output of ls, too many things can go wrong. A simple way to accomplish your goal would be
for f in *.vital; do
echo -n "$f: "
jq '.author' "$f"
done
which might still fail if there are directories matching the pattern for instance. You can overcome this by using
for f in *.vital; do

sudo on macOS does work as it does on other platforms - at least through macOS 10.15.6:
If you, as a "Standard" user, want or need privileges to perform certain tasks, those privileges may be granted by the Admin user in the sudoers file. If you are both the Admin user, and the unprivileged StandardJoe user, this becomes a bit trite, but here's how ...

The relevant file for that specific dmg is SecUpd2020-006Mojave.pkg/PackageInfo.

This has nothing to do with iTerm, but rather the shell that you're using and whether or not the option interactive_comments is enabled or not. To treat the line as a comment, you have to start the line with a comment character.

As explained in https://stackoverflow.com/questions/56951712/why-is-zsh-not-able-to-read-tilde-from-a-path-in-a-script zsh doesn't expand ~ within double quotes. So you can do one of
export ZSH=~"/.oh-my-zsh"
export ZSH="$HOME/.oh-my-zsh"
(where the second option also works if there are space characters in your home path), or set

Do you know of a way to automatically log commands that return successfully ... in order to keep a record of how you managed to finally successfully set up your environment to compile that one stubborn piece of code?
You first need to answer the question What constitutes a successful command?

i know this seems like a locale problem -- i spent of bunch of time looking into that but it turns out this is actually a problem with the date command.
from the man page for date:
%U week number of year, with Sunday as first day of week (00..53)
%W week number of year, with Monday as first day of week (00..53)
so if i rewrite your command to use %U ...

All Cmd. does is sending CtrlC to the shell running in the current Terminal tab/window.
So you can get the same effect in iTerm2 by just typing CtrlC.

/usr/libexec/path_helper is used to build PATH from the default in /etc/paths and the entries in /etc/paths.d (see man path_helper for details). By default this is called in /etc/profile which is executed for each sh/bash/zsh style login shell.
On my system /etc/profile looks like this
# System-wide .profile for sh(1) and friends

Looking back, past crashes are logged in the log system, and also individual dump files are saved for about a month in /Library/Logs/DiagnosticReports
Looking forward, to cause them is a bit harder and risky. You could try issuing a SIGABRT or SIGQUIT signal if you know the process:

The message Homebrew shows you after installing curl gives you all the required details
==> Caveats
curl is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.
If you need to have curl first in your PATH run:
echo 'export PATH=...

As user3439894 stated in the comment already, there is a history file recording all commands issued on the command line regardless of success or failure. This list of commands is finite, however, and will toss off the oldest command after having issued a number of commands. I have not checked, but I think on average that would be somewhere between 500-1000 ...

I agree that I wouldn't change the global LC_COLLATE.
Just use it locally in your alias:
alias ls="LC_COLLATE=cs_CZ.ISO8859-2 /bin/ls"
Watch out for the undesirable effect of this particular LOCALE. Files that start with "ch", "CH", or "Ch" will be sorted between files that
start with "H" and "i".
