將代碼附加到代碼塊時終止了's'命令

Question

這是我想要更改的文件。我想在servers {下添加一個條目。

eap-radius { 

    # Section to specify multiple RADIUS servers. 
    servers { 

    } 
} 

這是我曾嘗試

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 

的sed：-e表達式＃1，焦炭81：未結束的'S'命令

Answer 1

我想你需要逃跑換行：

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

結果是（我也是標籤有點server-a塊）：

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 
     } 

    } 
}
