In a very long script I have to construct several paths for use. Problem is the paths are getting mangled. Most easily seen with echo.
For example:
var = /opt/big_program
new_var = ${var}/sub_folder
echo "Look at what happens: ${new_var}"

/sub_foldert happens: /opt/big_program

The end of the first variable must contain a 'return line' character, and is resetting the cursor before it continues, overwriting what's already there. Chances are this file (or one it reads the paths from) was created on Windows, which uses a different character to signal the end of a line.

To fix, run:
sed -i 's/\r//' $file_name

Props, and endless thanks to the poster of the solution here: http://ubuntuforums.org/showthread.php?t=1239902
