bash变量-转义点

Question

Im trying to save text in variable. But the point will translated as dir.

M2_1="GRANT USAGE ON *.* TO '$USER'@'%' IDENTIFIED BY PASSWORD '$MYSQL_PASSWORD';"

How can i escape *.* ?

example output should be:

GRANT USAGE ON *.* TO 'web88'@'%' IDENTIFIED BY PASSWORD '123456789';"

Answer 1

It works for me. You are probably not quoting the variable when using it later:

M2_1="GRANT USAGE ON *.* TO '$USER'@'%' IDENTIFIED BY PASSWORD '$MYSQL_PASSWORD';"
echo "$M2_1"
