Rather long, makes for good bedtime reading in that sense, but an interesting guide to what the standard Linux/MacOS shell can do.
These are often fun, though the list commits what I feel is a cardinal sin by demonstrating an imagemagick command (identify) without noting the command is part of imagemagick. It's not as common a package as it once was (it is installed on my system as a dependency of cups, but that's it), and its use of generic names for special-use commands is, shall we say, not good form.
While not a useful one-liner for a human, I used the following in a script this morning:
systemctl show $unit --property=UnitFileState --value systemctl show $unit --property=ActiveState --value
The information returned is otherwise provided by `systemctl status` with less typing, but the output of these is much more concise.
