Edit file on Windows, shows ^M on each line on Linux

[Joseph Hall]

Window and DOS use <CR><LF> as its end of line marker, whereas Unix
and Linux only use <LF>. When you open a Windows file in something
such as vi in Linux, you get ^M at the end, which represents the <CR>.

You can use dos2unix to stip the ^M from your files in Unix and Linux:

$ dos2unix filename.ext

Keep in mind that it will replace the original file with the converted file.
