Question

When I run

root@Nano:/etc/init.d# ./utserver

which is this script http://pastebin.com/c7gxFdci it gives me this output

": invalid option" 

no matter how the arguments are done.

Answer 1

Your file has DOS \\r\\n line endings. Here's the relevant section from the bash tag wiki :

1. Check whether your script or data has DOS style end-of-line characters

   • Use cat -v yourfile or echo "$yourvariable" | cat -v echo "$yourvariable" | cat -v .

     DOS carriage returns will show up as ^M after each line.

     If you find them, delete them using dos2unix (aka fromdos ) or tr -d '\\r'
