bad interpreter – no such file or directory

I hit this error recently “bad interpreter – no such file or directory” when I trying to run/execute a shell script in linux box. The shell script is quite simple, just to initialize a java class.

This “bad interpreter – no such file or directory” is cause by the line-feed / carriage-return issue among windows-linux OS. The shell script is initially written in windows before I ftp it into linux box and run.

To solve it, is very simple — dos2unix.
$> dos2unix my-script.sh

The dos2unix is DOS/MAC to UNIX text file format converter (according to linux manual). It helps to solve the CR/LF conflicts between windows and *nix.

Besides, do remember to do another command to make an .sh file executable in linux — chmod.

$> chmod +x my-script.sh
