How to remove all files except the ones you want:

First, expand rm capabilities by: shopt -s extglob

Then use find and remove: find . ! -name 'file.txt' -type f -exec rm -f {} +

Rename files

It has a lot of good options but one pretty useful for removing whitespaces and set all to lowercase:

rename -c --nows <fileName>

Use umask to restrict default permissions for users outside of the group

Set umask 007 in our .bashrc. Then newly created directories will have 770 (rwxrwx---) permissions, and files will have 660 (rw-rw----).
