find “$(echo $HOME > variable_holder.txt && cat variable_holder.txt)/$(cat alphabet.txt | grep “d”) $(cat alphabet.txt | grep “o”)$(cat alphabet.txt | grep “c”)$(cat alphabet.txt | grep “s”)”
This is the easiest method

To be safe, should probably output grep to a file, then cat that.

What should I search to better understand what is written here? Don’t mind learning myself, just looking for the correct keywords. Thanks!

This comment is a joke and you wouldn’t want to do it like that in reality, but here are some related keywords you could look up: “Unix cat”, “Unix pipeline”, “grep”, “output redirection”, “command substitution”.

Read the Bash manual. That one patter on the GP is called “Command Substitution”, you can search for it.
