What does that mean with respect to scripting and programming on a shared host?
- DOs
- Respect shared CPU/Disk/Network resources
- Keep things that require a Tilde.club login local to the server (don't post publicly), like home directory files:
- Note that exceptions could include an opt-in file or special permissions from the user.
- Respect `robots.txt` when writing web crawlers

- CPU
- Use the `nice` command to keep intensive processes from affecting others
- The `nice -n19 -p$$` placed in a script will make sure it runs at the lowest priority.
- Run a long command at the lowest CPU priority: `nice -n 19 ~/bin/command`
- Change the priority of process 923 (also known as "re-nicing a process") : `renice -17 -p923`

- Disk
- On any commands that will heavily use disk, consider using the `ionice` command so that scripts will not affect interactive users
- By adding the `ionice -c3 -p$$` command to any script, it will only use disk when idle.
- You can also run a command or script: `ionice -c3 -t ~/bin/command`
