mysql - Bash: How to invoke command and store the result in a variable?

Basically I want to be able to invoke a given command, in this case mysql -uanon -ppwd -db mydb -e "select count(*) from table1". And then take this commands result (the count on that table) and place it in a variable in bash script. What is the simplest way to achieve this?

You most likely want to use batch mode (-B) and disable column names (--disable-column-names) for non-interactive mysql output:

out=$(mysql -B -db mydb -uanon -ppwd --disable-column-names  -e "select count(*) from table1";)
