Execute multiline mysql in shellscript

For future readers, one easy way is as follows if they wish to export in bulk using bash, tested on mariadb, same should work in mysql too.

akshay@ideapad:/tmp$ mysql -u someuser -p test -e "select * from offices"
Enter password:

If you're exporting by non-root user then set permission like below

root@ideapad:/tmp# mysql -u root -p
MariaDB[(none)]> UPDATE mysql.user SET File_priv = 'Y' WHERE user='someuser' AND host='localhost';

Restart or Reload mysqld

akshay@ideapad:/tmp$ sudo su
root@ideapad:/tmp#  systemctl restart mariadb

Sample code snippet

akshay@ideapad:/tmp$ cat test.sh 
#!/usr/bin/env bash

user="someuser"
password="password"
database="test"

mysql -u"$user" -p"$password" "$database" <<EOF
SELECT * 
INTO OUTFILE '/tmp/csvs/offices.csv' 
FIELDS TERMINATED BY '|' 
ENCLOSED BY '"' 
LINES TERMINATED BY '\n'
FROM offices;
EOF

Execute

akshay@ideapad:/tmp$ mkdir -p /tmp/csvs
akshay@ideapad:/tmp$ chmod +x test.sh
akshay@ideapad:/tmp$ ./test.sh 
akshay@ideapad:/tmp$ cat /tmp/csvs/offices.csv

The syntax for bash heredoc is:

COMMAND <<InputComesFromHERE
...
...
...
InputComesFromHERE

So you have an extra <.

In order to prepare and test you can replace COMMAND (i.e. mysql -uroot -ppass mydb in this case) with cat to have a look at the exact SQL code that will be executed.
