Question

I have such file and I would like to replace $GLOBALS['SERVER_MEMCACHED']='localhost'; with $GLOBALS['SERVER_MEMCACHED']='mydomain.com'; using sed.

How to do this ? I don’t want to replace the DB_HOST too.

<?php
$GLOBALS['DB_HOST']='localhost';
$GLOBALS['DB_NAME']='database';
$GLOBALS['DB_LOGIN']='login';
$GLOBALS['DB_PASSWORD']='password';
$GLOBALS['PORT_MYSQL']='3306';
$GLOBALS['PORT_MYSQLI']='3306';
$GLOBALS['SERVER_MEMCACHED']='localhost';
$GLOBALS['PORT_MEMCACHED']='11211';
$GLOBALS['CACHE_TIME']=600;
?>

Answer 1

sed -i '/SERVER_MEMCACHED/s/localhost/mydomain.com/' input
