Bash script and mysql


I'm trying to use a bash script to query mysql and extract a number from a table then do something with the number.

This gives me a nice clean output without the little mysql box or column name:

mysql --skip-column-names -B -s -e "use proftpd; select max(uid) from users;" --password=$MYSQLPASSWORD

The idea is to create users in a mysql authentication backend for proftp--the script above gives the highest user id --- what I would like the bash script to do is assign the next available number -- so the above script + 1

I cant get bash to accept the output of the above as a variable

If someone can help I would sure appreciate it


Thanks


Dan

Hi,
try
Code:
bash_var=`mysql --skip-column-names -B -s -e "use proftpd; select max(uid) from users;" --password=$MYSQLPASSWORD`
bash_var=`expr $bash_var + 1`
Remember, the commands are surrounded by grave accent.
