Code:

f1() {
echo $1 $2 $3 "line" $4

Here f1 is a simple function to test the function g1.
g1 is a function which tests the parameters format of an input file.
Theses parameters are YEAR BEGIN_hour END_hour.
Month must be between 1 and 12
Day must be between 1 and 31
Hour must be between 00 and 23 (2 digits)
Minutes must be between 00 and 59 (2 digits)

case 0)
If the script is launched without argument, an inputfile named list_file will be created with comments.
The main engine ie case 1)
If the inputfile exists, the script tests if there are parameters.
Then it parses each parameters to check the validity of the format

When i launch the script, there are malfunctions.
1) Each line with right or wrong parameters are printed twice.
I would like the line that has an error is not printed. It should only return the error code.
And others to be edited once.

I hope to be clearer.

Have a nice day.

Code:

case $# in
        0)      echo -e "# comment1\n# comment2" > list_file
                read -p "Please fill in this list_file: "

                echo $REPLY
                ;;
        1)     if [ ! -f "$1" ]
               then  > $1 && echo -e "# comment1\n# comment1" > $1
                        read -p "Please fill in "$1": "

                        echo $REPLY
               else
                        if [ -f "$1" -a $(grep -v '^#' "$1" | wc -l ) -ne 0 | $(g1 $arg1 $arg2 $arg3) -ne 0 ] # line 58
                        then
                                grep -v '^#' "$1" |
                                                while read arg1 arg2 arg3
                                                do f1 $arg1 $arg2 $arg3
