Question

I am getting the error: line 34: #10#1001: syntax error: operand expected (error token is “#10#1001”)

I have just changed

[! -f INPUT ] & 

to

[ ! -f INPUT ] &&

and now i am getting the error

line 34: #10#1001: syntax error: operand expected (error token is "#10#1001")

when i run the script.

The script inputs users names, phones numbers and dob and then sorts the infomation and calculates their ages.

What could be causing this error as i cannot work out what operand it is demanding

#!/bin/bash

a=0
while [ $a -lt 2 ];
do
    echo Please enter a first name
    read firstName
    echo Please enter last name
    read lastName
    echo Please enter phone number
    read phoneNumber
    echo Please enter date of birth - format dd/mm/yyyy
    read dob
    echo "$firstName,$lastName,$phoneNumber,$dob" >> userBirthdays.csv
    echo If you would like to add another person press 1 or enter 2 to proceed
    read a
done

    INPUT=./userBirthdays.csv
    OLDIFS=$IFS
    IFS=","
    [ ! -f INPUT ] && while read  while read Name Surname Telephone DOB
    do
                    birthMonth=${DOB:0:2}
                    birthDay=#10${DOB:3:2}
                    birthYear=${DOB:6:4}

                    currentDate=`date +%d/%m/%Y`

                    currentMonth=${currenDate:0:2}
                    currentDay=#10${currentDate:3:2}
                    currentYear=${currentDate:6:4}

                    if [[ "$currentMonth" -lt "$birthMonth" ]] || [[ "$currentMonth" -eq "$birthMonth" && "$((#10$currentDay))" -lt "$((#10$birthDay))" ]]
                    then
                            let Age=currentYear-birthYear-1
                    else
                            let Age=currentYear-birthYear
                    fi

            echo "Name : $Name"
            echo "Surname : $Surname"
            echo "Telephone : $Telephone"
            echo "DOB : $DOB"
            echo "Age : $Age"
            echo "##########################################"
done < $INPUT
IFS=$OLDIFS
    echo $DATE

exit 0;

Answer 1

You have two mistakes on this line:

[ ! -f INPUT ] && while read  while read Name Surname Telephone DOB

It should be:

[ -f ${INPUT} ] && while read Name Surname Telephone DOB

I recommend debugging your script with:

bash -x /path/to/birthdays.bash 

This will print command traces before executing each command.
