The quickest method to install the script is to run:
$ curl https://raw.githubusercontent.com/Will-Hoey/todo-finder/main/todof > ~/.local/bin/todof
and make sure the script is an executable with
$ chmod 700 ~/.local/bin/todof
In order to install and run this script, run git clone git:github.com:Will-Hoey/todo-finder
Once you have installed it you can run this like any other script
$ bash /path/to/script/todo_finder.sh
Note that this will run the script in the current working directory. This means that if you run it in /home or a directory with a large number of subfolders, it WILL output everything.
A better method for running this script is to create an alias. The method in which you setup an alias will vary depending on what shell you are using.
Bash:
$ alias_name="bash /path/to/script/todo_finder.sh"
Fish:
alias -s alias_name="bash /path/to/script/todo_finder.sh"
