linux：sed -e表达式错误

Question

Im trying to use sed to recursively replace mysql string, like this

find /var/www/html -type f -exec \
sed -i 'mysql_real_escape_string(/$conn->qStr(/g' {} +

the objective

find: mysql_real_escape_string(
replace to: $conn->qStr(

but it gives me error:

sed: -e expression #1, char 1: unknown command: `m'
sed: -e expression #1, char 1: unknown command: `m'
sed: -e expression #1, char 1: unknown command: `m'

any help would be great. thanks

You should supply the s command:

find /var/www/html -type f -exec \
sed -i 's/mysql_real_escape_string(/$conn->qStr(/g' {} +
