List of random things I keep forgetting

I often end up looking for certain commands/ code snippets so here is a list.

1. Change the server language to English: export LC_ALL=C
2. Look at the username for of who is running a process on a multi-user server: ps -u -p <PROCESS_ID>
3. Re-authenticate with github after your PAT has expired: gh auth login -h [github.com](http://github.com/)
4. Pip install without clogging the cache dir, add a --no-cache-dir flag to your pip install commands.
5. Create a virtual environment with python -m venv <path_to_the_environment> command.
6. Run a python script with nohup and pipe the output to a file. nohup python my_script_is_the_best.py &> my_scripts_output.out 2>&1 &
7. Batch convert wav files to mp3 files with ffmpeg - for f in *.{wav,WAV}; do ffmpeg -i "$f" -c:a libmp3lame -q:a 2 "${f%.*}.mp3"; done
8. Append a prefix to specific files in a directory - for f in {0,1,2,3,4,5}.mp3; do mv "$f" "GAN_$f"; done
