Using a shell script to parse through a CSV file and add users using the ldapadd command

Question

Good evening all,

As the title says, I am attempting to parse through a csv file of about 400 lines and add each one using the below script. This is part of a homework assignment and I am not sure what exactly I am doing wrong.

#!/bin/bash
while IFS=, read -r userName firstName lastName gender dob language bloodType zodiac constellation planet genre dino;
do
        ldapadd -x -w 1234568 -D cn=admin,dc=SAMPLE,dc=CLASS,dc=SCHOOL,dc=edu
        dn: uid=$userName,ou=people,dc=SAMPLE,dc=CLASS,dc=SCHOOL,dc=edu
        objectClass: person
        objectClass: top
        objectClass: inetorgperson
        uid: $userName
        cn: $firstName $lastName
        sn: $lastName
        description: $dob
done < Males.csv

I am unsure what I am doing wrong, as I keep getting the error: "ldapadd: invalid format (line 1) entry: """

@cas I was unaware of 3. That is, I didnt know about backslash-escaping new lines. Thank you. — Allen, Nov 30 '21 at 19:45

ldapadd expects dn: ... from standard input. You need a "Here document":

#!/bin/bash
while IFS=, read -r userName firstName lastName gender dob language bloodType zodiac constellation planet genre dino;
do
ldapadd -x -w 1234568 -D cn=admin,dc=SAMPLE,dc=CLASS,dc=SCHOOL,dc=edu <<EOF
dn: uid=$userName,ou=people,dc=SAMPLE,dc=CLASS,dc=SCHOOL,dc=edu
objectClass: person
objectClass: top
objectClass: inetorgperson
uid: $userName
cn: $firstName $lastName
sn: $lastName
description: $dob
EOF
done < Males.csv

Do not! use indentation inside here documents.

That worked. Thank you so much for your help. I had suspected EOF was the key, but I was unsure how to use it. – Allen Nov 30 '21 at 19:44
+1. BTW, you can use indentation in here docs by using <<- instead of just <<. From man bash: "If the redirection operator is <<-, then all leading tab characters are stripped from input lines and the line containing delimiter. This allows here-documents within shell scripts to be indented in a natural fashion." – cas Dec 01 '21 at 01:12
@cas Yes, but tab was a bad choice because you can't safely paste tabs into interactive shell – basin Dec 01 '21 at 08:15
true, but not really relevant in a script. – cas Dec 01 '21 at 11:45
