HowTo convert Windows or DOS text to Linux

If you write text file in Windows, it won't be displayed correctly in Linux, because Windows' editors add carriage return symbol (\^) to the end of each line.
I wrote very simple (but useful) script to migrate text files from Windows to Linux.
Here it is:

dos2linux.sh

#!/bin/bash

cat $1 | tr -d '\r' >$1.fixed

Command "./dos2linux.sh text.txt" reads file "text.txt" and writes fixed file to "text.txt.fixed".

It works on Linux/Unix platforms or under Cygwin environment.
