PATH tips on wizard zines
(via)
New Julia Evans comic, from which I learned that the which -a X command shows you all of the versions of that command that are available in the directories on your current PATH.
This is so useful! I used it to explore my currently available Python versions:
$ which -a python
/opt/homebrew/Caskroom/miniconda/base/bin/python
$ which -a python3
/opt/homebrew/Caskroom/miniconda/base/bin/python3
/Library/Frameworks/Python.framework/Versions/3.13/bin/python3
/Library/Frameworks/Python.framework/Versions/3.12/bin/python3
/opt/homebrew/bin/python3
/usr/local/bin/python3
/usr/bin/python3
/Users/simon/Library/Application Support/hatch/pythons/3.12/python/bin/python3
/Users/simon/Library/Application Support/hatch/pythons/3.12/python/bin/python3
$ which -a python3.10
/opt/homebrew/Caskroom/miniconda/base/bin/python3.10
/opt/homebrew/bin/python3.10
$ which -a python3.11
/opt/homebrew/bin/python3.11
$ which -a python3.12
/Library/Frameworks/Python.framework/Versions/3.12/bin/python3.12
/opt/homebrew/bin/python3.12
/usr/local/bin/python3.12

$ which -a python3.13

pyp: Easily run Python at the shell (via) Fascinating little CLI utility which uses some deeply clever AST introspection to enable little Python one-liners that act as replacements for all manner of pipe-oriented unix utilities. Took me a while to understand how it works from the README, but then I looked at the code and the entire thing is only 380 lines long. There’s also a useful --explain option which outputs the Python source code that it would execute for a given command.

direnv (via) A shell extension (for bash, zsh and others) which can automatically set and unset environment variables when you cd into specific directories. Useful for managing things like a project’s GOPATH or automatically activating Python virtual environments.

What is a good programming language to learn after bash scripting?
Python is a good natural progression from bash in my opinion. It has an interactive prompt which supports bash-style exploratory programming, and it has libraries that mean it can be applied to an enormous range of problems—everything from game development to scientific computing to web applications.
