@derksuh
you’re having dos/windows line endings at the end of each line.
do the following
sudo apt-get install dos2unix
then
dos2unix uptime.sh

this should do it. the program removes the windows line endings.

@leader21

Thanx!! Problem solved!

you’re welcome!
this often happens when you copy and paste from the web or using windows editors to create scripts for linux. but now you know what to do in the future

Yeah that’s right.
But when i edit the config file in windows i never get an error why is that?

depends on the editor i guess. if using notepad++ for example you should not face this issue.

Even in notepad++ you have to tell it in options that a new file should be Windows or Unix (or MAC) style!
