dos2unix - A script to convert DOS to LINUX formatting #iLoveScripting

dos2unix - a simple filter to convert text files in DOS format to UNIX/LINUX end of line conventions by removing the carriage return character(\r).  This will leave the newline character(\n) which unix expects.

Usgae:
dos2unix [file1] :  Remove DOS End of Line (EOL) char from file1, write back to file1
dos2unix [file1] [file2] : Remove DOS EOL char from file1, write to file2
dos2unix -d [directory] : Remove DOS EOL char from all files in directory
