I am trying to do the following search and replace, but for some reason it's not working. I am trying to replace:
require_once('
with
require_once($_SERVER['DOCUMENT_ROOT']/'
Those are the exact srings (slash and single quote included).
This is what I attempted, however I can't get it to work:
find ./ -type f -readable -writable -exec sed -i "s/require_once(\'/require_once($_SERVER['DOCUMENT_ROOT'] . \'\//g" {} \;
What am I doing wrong??
你需要转义$
和/
字符:
sed "s/require_once('/require_once(\$_SERVER['DOCUMENT_ROOT']\/'/g"
你需要反斜杠 - 在双引号内转义美元符号,否则shell会插入(不存在的)环境变量_SERVER
,用空字符串替换它。
