Script to add users to mariadb - database

Question

I am trying to add users into mariadb. Male users use an airline as password and females use a continent as a password all this info is taken form a csv file.
For some reason my script is not working. here is the script:
#!/bin/bash -p
FILENAME=mgarr048.csv
while IFS=: read -r username first last gender dob state municipality season continent elective f1 airline
do
(( gender == "m" )) || continue
mysql -e GRANT INSERT ON *.* to $username#'%' IDENTIFIED by $airline;
done
csv headers
username,first,last,gender,dob,state,municipality,season,continent,elective,f1,airline

Answer 1

Nowhere in your script you tell it to read FILENAME. Modify your script like this:
#!/bin/bash
FILENAME="mgarr048.csv"
while IFS=, read -r username first last gender dob state municipality season continent elective f1 airline
do
if [[ "$gender" != "m" ]]
then
echo "mysql -e GRANT INSERT ON *.* to $username#'%' IDENTIFIED by "$airline""
fi
done < "$FILENAME"
You said you have a CSV file, so I changed IFS=; to IFS=,. C in CSV is "comma".
You can read a full description on bash loops to read files here: https://mywiki.wooledge.org/BashFAQ/001
EDIT
Since I do not have your database to test, I added echo to the mysql line. Remove it to use this on your system. If you get a mysql error, it is not the script, it is related to your mysql command and/or database.
Tested with that data set:
username1,user1,name1,m,1111-11-11,State1,City1,season1,continent1,elective1,f1,airline1
username2,user2,name2,f,2222-22-22,State2,City2,season2,continent2,elective2,f2,airline2
Output:
mysql -e GRANT INSERT ON *.* to username2#'%' IDENTIFIED by airline2
