This is a bash script I ran on cygwin that finds all the php files in a directory tree and converts them from lf to crlf

lf2crlf

#!/bin/bash
FOLDER=$(pwd)
arrayname=( $(find $FOLDER -name '*.php') )
fixarray=()

for element in $(seq 0 $((${#arrayname[@]} - 1)))
    do
        filename=${arrayname[$element]};
        fileOut="$(file $filename)";
        if [[ $fileOut != *"CRLF"* ]];
        then
            fixarray+=( "${arrayname[$element]}" )
        fi
    done

for element in $(seq 0 $((${#fixarray[@]} - 1)))
    do
        echo "${fixarray[$element]}"
    done

echo 'Convert the files above to CRLF? (y/n)'
read SELECTION

if [ ${SELECTION} == "y" ];
then
    for element in $(seq 0 $((${#fixarray[@]} - 1)))
        do
            echo "${fixarray[$element]}"
            perl -pi -e 's/\n/\r\n/' "${fixarray[$element]}"
            rm "${fixarray[$element]}.bak"
        done
else
    echo "Not doing anything!"
    exit
fi
