I’ve been writing a few bash scripts and some Nim command line utilities.
You can run a script from the folder which contains the script. Here’s an example file structure:
~/bin/
├── git-reset-author.sh
└── readme_template
When I’m inside the ~/bin directory, I can type into the terminal: readme_template.
But what if I want to navigate to a different folder on my machine and run the script from that location?
fish: unknown command readme_template
The shell doesn’t find the program.
You can add the folder with your scripts to your user path.
For Bash:
export PATH="$HOME/bin:$PATH"
You have to add it to your shell configuration, e.g. ~/.bashrc if you want to have it work across reboots.
For Fish:
Fish has a variable called fish_user_paths to which you can prepend the folder with your scripts:
set -U fish_user_paths $HOME/bin $fish_user_paths
