help for script

@wsamael said in help for script:

@Clyde the first solution it's for convert my script to unix script ?

Both are. The first doesn't require the installation of another tool, as sed is party of most Linux base installations; the second may be more easy to remember as something like 's/\r$//'. ;)

I try

sed -i 's/\r$//' root.sh

it's work but I see no difference beetwen my script, how did you see what 's wrong with my script ? (i would be understand ^^ )

@wsamael Your error message said:

'\r': command not found

Windows ends a line in a text file with a carriage return (\r) and a line feed (\n), wheras unixoid systems only use \n. Thus Retropie's command shell bash rejected the \r in your file as an unknown command.

ok i understand thank you ;)
