Artificial intelligent assistant

A basic function that doesn't work I've tried several modifications to see why it's not working, but I can't find the answer. Here is my code, this is in french but this is just a normal fonction that ask to the user if he's ready to start. #!/bin/ksh function start { echo "Vous etes sur le point de lancer la generation, etes-vous pret(e)? [OUI/NON]" read touche case $touche in [Oo] | [Oo][Uu][Ii] ) echo "Demarage du bash..." ;; [Nn] | [Nn][Oo][Nn] ) echo "Annulation du bash..." exit ;; esac } start This is what I get : sh start.sh : unfindable command »art.sh: line 3: syntax error close to the « symbol 'tart.sh: line 3: `function start

My file was saved in DOS Format, I used dos2unix start.sh to convert it.
