如何使用管道解析命令的输出
原标题:How to use pipe to parse output of a command

我想处理一个进程的输出, 比如 ifconfig 。 正如大家所知, ifconfig 的输出是包含 inet addr: 掩码的行列表 : 等 。 但我想单独从 inet addr: field] 提取 ip 并列出它 。 在管道命令下是否可行?

ifconfig | What should be here?

我要将此命令的输出作为 inet 地址 (如果存在不同的访问点) 的列表 。

ifconfig\\ awk/ dr:/{gsub (/. *: / : /, /, /, /,,,,, $2, print 2}

问题回答

你可以做到

 ifconfig -a|grep inet| awk -F     {print $2}
