Extract and delete all .gz in a directory- Linux

Question

I have a directory. It has about 500K .gz files.

How can I extract all .gz in that directory and delete the .gz files?

Answer 1

This should do it:

gunzip *.gz 

Answer 2

@techedemic is correct but is missing '.' to mention the current directory, and this command go throught all subdirectories.

find . -name '*.gz' -exec gunzip '{}' \;
