How to change all occurrences of a word in all files in a directory

I was in the process of creating a User class where one of the methods was get_privileges();.

I generally use this short script, which will rename a string in all files and all directory names and filenames. To use it, you can copy the text below into a file called replace_string, run sudo chmod u+x replace_string and then move it into your sudo mv replace_string /usr/local/bin folder to be able to execute it in any directory.

NOTE: this only works on linux (tested on ubuntu), and fails on MacOS. Also be careful with this because it can mess up things like git files. I haven't tested it on binaries either.

#!/usr/bin/env bash

# This will replace all instances of a string in folder names, filenames,
# and within files.  Sometimes you have to run it twice, if directory names change.


# Example usage:
# replace_string apple banana

echo $1
echo $2

find ./ -type f -exec sed -i -e "s/$1/$2/g" {} \;  # rename within files
find ./ -type d -exec rename "s/$1/$2/g" {} \;    # rename directories
find ./ -type f -exec rename "s/$1/$2/g" {} \;  # rename files
