ubuntu - 用 Sed 用回车替换行

Question

我有以下要更改的文件:

authorize {
        update request {
                Monthly-Usage = "%{sql:SELECT COALESCE((SUM(`acctoutputoctets`)), 0) FROM radacct WHERE `username`='%{User-Name}' AND Month(acctupdatetime)=(Month(NOW())) AND Year(acctupdatetime)=Year(NOW())}"
        }

    filter_username
    etc


}

使它变成这样(更新请求 { ... } 被删除)

authorize {

    filter_username
    etc
}

我查找了一些示例并想出了这个，但它不起作用:

sed -i 'N; s/update request {\nMonthly-Usage = "%{sql:SELECT COALESCE((SUM(`acctoutputoctets`)), 0) FROM radacct WHERE `username`='"'"'%{User-Name}'"'"' AND Month(acctupdatetime)=(Month(NOW())) AND Year(acctupdatetime)=Year(NOW())}"\n}//g' /etc/freeradius/3.0/sites-enabled/default

Answer 1

这可能对您有用(GNU sed):

sed '/^authorize {$/,/^}$/c\authorize {\n ...\n}' file

使用范围来更改文件。
