bash - 将代码附加到 block 时 sed 未终止 `s' 命令

Question

这是我要更改的文件。我想在 servers { 下添加一个条目。

eap-radius {

    # Section to specify multiple RADIUS servers.
    servers {

    }
}

这是我试过的

sed -i '/servers {/a\
server-a {
            accounting = yes
            secret = 123456
            address = 127.0.0.1
            auth_port = 1812
            acct_port = 1813
}
' /etc/strongswan.d/charon/eap-radius.conf

sed: -e expression #1, char 81: unterminated `s' command

Answer 1

我认为你需要转义新行:

sed '/servers {/a\
        server-a {\
            accounting = yes\
            secret = 123456\
            address = 127.0.0.1\
            auth_port = 1812\
            acct_port = 1813\
        }
' ./test.txt

结果是(我还标记了一点 server-a block ):

eap-radius {

    # Section to specify multiple RADIUS servers.
    servers {
        server-a {
            accounting = yes
            secret = 123456
            address = 127.0.0.1
            auth_port = 1812
            acct_port = 1813
        }

    }
}
