Execute dos2unix for directory recursively.

dos2unix.md

Will recursively find all files inside current directory and call for these files dos2unix command. Would break if you had spaces in file name.

find . -type f -exec dos2unix {} \;

Wouldn't break if you had spaces in file names.

find . -type f -print0 | xargs -0 dos2unix

Convert only *.php files

find . -type f -name "*.php" -print0 | xargs -0 dos2unix

If it's a large directory you may want to consider running with multiple processors:

find . -type f -print0 | xargs -0 -n 1 -P 4 dos2unix 

This will pass 1 file at a time, and use 4 processors.

Nice :)
