Have you ever copied a bash or any other script written your favorite windows editor to UNIX environment and saw it does not work?
Yeah? Well its a Line terminator issue between windows and Linux environment. The enter key, in windows appends a CR and LF code into the end of the line; where in *nix only CR is appended at the end of the line.
Check the script with cat -v, if it display something ^M at the end of the line, that means this text file was created under windows environment. And CR LF is causing the execution of bash script to fail.
$cat -v WonderScript.sh
Once identified, this issue can easily be fixed with the dos2unix command.
$dos2unix WonderScript.sh
$chmod +x WonderScript.sh
$./WonderScript.sh
That's it !!
Cheers!
