There are many files that have Unix line endings ("\n") whilst there are a substantial number of files that have DOS line endings ("\r\n") as well. To synch it all to have just Unix line endings except for the BAT files needed for Windows would be appropriate.
This can be achieved using the bash oneliner:
find ./ -type f -name "*.php" -o -name "*.css" -o -name "*.js" -o -name "*.txt" -o -name "*.inc" -o -name "*.sql" | xargs dos2unix
Some Linux installs may need a trailing ' -U' like:
find ./ -type f -name "*.php" -o -name "*.css" -o -name "*.js" -o -name "*.txt" -o -name "*.inc" -o -name "*.sql" | xargs dos2unix -U
