Hello,
Thanks for yours explainations.

I have another question if you have some time.
I tried that ie put the arguments after the command

./ my_script QCVD UPG8 22 16 server 2013-01-24

What should I change to make it work in magenta ?

Code:
#!/bin/bash

        esac

        0[1-9]) ;;
        1[0-2]) ;;
        *) return 1 ;;

        return 0
}
process() {
echo "$CONTEXTE $INSTANCE $HH $MM $type_log $DATE"
}

while read CONTEXTE INSTANCE HH MM type_log DATE
do
        [ "${DATE:0:1}" = "#" ] && continue # Ignore comments
        [ -z "$DATE" ] && continue # Ignore blank lines
        if ! valid $CONTEXTE $INSTANCE $HH $MM $type_log $DATE # Ignore invalid lines
        then
                echo "$CONTEXTE $INSTANCE $HH $MM $type_log $DATE is invalid"
                continue
        fi

        process $CONTEXTE $INSTANCE $HH $MM $type_log $DATE
done

Well, the 'while read' loop and command reads from stdin. If you don't want to read from stdin, don't.

The parameters will be available as $1 $2 ... so just call your function with these options

Hello,
Sorry, I don't speak fluent English and I don't understand all the idiomatic forms. I don't quite understand your suggestions.
But i tried that.

Thank you in advance.

Code:
process() {
     echo "$1 $2 $3 $4 $5 $6"
     }
      if ! valid $1 $2 $3 $4 $5 $6 # Ignore invalid lines
     then
     echo "$1 $2 $3 $4 $5 $6 is invalid"
     else
      process $1 $2 $3 $4 $5 $6
     fi

It doesn't work, i have the same result invalid.

With good arguments
Code:
./my_script 2013-03-13 22 25 server
2013-03-13 22 25 server   is invalid

With bad argument in red
Code:
./my_script 2013-03-35 22 25 server
2013-03-35 22 25 server   is invalid

Your arguments are totally different from your config file again and the function will have to be altered.

There's no QCVD UPG8 for instance.
