Delete Files with mac terminal

Question

I'm trying to use find in the terminal to delete some files that PyCharm has created seemingly at random. It's created duplicates of files like:

manage.py
manage 2.py
manage 3.py
index.js
index 2.js

So the pattern I'm trying to match is a string followed by a space and then a number with different endings. Currently I'm trying:

find pathToMyFiles -type -f -regex '.+?\w+ [0-9](.py|.js)$' 

This fails to identify any files in the directory even though it captures my test strings when I go to regexer or any of the other regex test sites, am I missing something that's mac terminal exclusive? I know this script will not delete any files, I'm just trying to make sure I'm correctly identifying them first.

Answer 1

Instead of regular expressions, you could combine two -name statements:

$ find -name '* [[:digit:]].py' -o -name '* [[:digit:]].js'
./manage 2.py
./manage 3.py
./index 2.js

This finds anything that ends in a blank and a digit with extension .py or .js .

If you want to use your regex, you have to escape a few things differently (see default regular expression syntax ):

$ find -regex '.+\w+ [0-9]\.\(py\|js\)$'
./manage 2.py
./manage 3.py
./index 2.js

() for capture groups, | for alternation and . for literal period all have to be escaped. .+? is not a valid combination.
