Find a file by extension

This comes in handy whenever I want to look for files that exists with a specific extension in a computer or server:

find . -name "*.ext"

In addition, sometimes, you might want to look for a bunch of files with a specific extension but with matching keywords:

find .name "*.ext" | grep "keyword"

BONUS: Display list of files by extension with file sizes

Last month, I was trying to free up some space in our company server, so I realized that there were a lot of .zip files taking up a lot of space. So, I wrote a few commands to get me a list of zip files with their file sizes in sorting order into a .txt file:

find . -iname \*.zip -exec du -sh {} \; > zipfiles.txt
sort -rh zipfiles.txt > newfile.txt

You can .zip with any extension to suit your needs! :)
