netcat实用程序有什么替代方案吗？我想运行docker API并且客户端系统上没有安装netcat实用程序.docker命令示例 - echo -e"GET/info HTTP/1.0\r \n"| nc -U /var/run/docker.sock

我有以下两个清单 -

list1 = List(("jira","ABC"),
             ("collApp","ABC"),
             ("amarColl","ABC"),
             ("Ubuntu1404","PQR"),
             ("relColAdmin","XYZ"))

list2 = List(("Linux_server","Hyper-V","suseLinux"), 
             ("Linux_server","VmWare","collApp"), 
             ("Linux_server","VmWare","relColAdmin"), 
             ("Linux_server","VmWare","amarColl"),
             ("Linux_server","Hyper-V","ubuntu1310"))

从上面的两个列表我想检查第二个列表是否包含list1的每个元素(元组)的第一个值,如果匹配则在list2中插入第二个值,否则在list2中插入空值.

这是样本输出 -

output = List(("Linux_server","Hyper-V","suseLinux",""),
              ("Linux_server","VmWare","collApp","ABC"),
              ("Linux_server","VmWare","relColAdmin","XYZ"),
              ("Linux_server","VmWare","amarColl","ABC"),  
              ("Linux_server","Hyper-V","ubuntu1310",""))
