Inspecting path
The $PATH is one of the most essential environment variables, since it points to all of your executables. Sometimes your path does not contain what you expect and you want to have a look at it.
I used to just call env and then grep for PATH, this is however not so efficient, so I made this little alias:
alias path="echo $PATH | tr ':' '\n'"
Which formats the output to something more readable.
And as I recently picked up gum I can even do a combination:
path | gum filter
Then I can filter in my path, if I am unsure of what things are called.
