最近在服务器调试东西的,在输出内容的同时也需要把内容输出到一个指定的文件,这个时候tee命令是我们的首选,接下来吾爱编程就为大家介绍一下tee 命令使用详解,有需要的小伙伴可以参考一下:
1、简介:
tee命令用于将标准输入复制到每个指定文件,并显示到标准输出。tee指令会从标准输入设备读取数据,将其内容输出到标准输出设备,同时保存成文件。
2、语法:
tee [选项]... [文件]...
3、参数:
-a, --append 内容追加到给定的文件而非覆盖 -i, --ignore-interrupts 忽略中断信号 --help 显示此帮助信息并退出 --version 显示版本信息并退出 如果文件指定为"-",则将输入内容复制到标准输出
4、实例:
(1)、在输出到控制台的时候,将内容保存到itbianhcneg.log
[root@localhost ~]# ping www.itbiancheng.com | tee itbiancheng.log PING www.itbiancheng.com.cname.yunjiasu-cdn.net (58.211.137.139) 56(84) bytes of data. 64 bytes from 58.211.137.139 (58.211.137.139): icmp_seq=1 ttl=56 time=12.5 ms 64 bytes from 58.211.137.139 (58.211.137.139): icmp_seq=2 ttl=56 time=12.6 ms 64 bytes from 58.211.137.139 (58.211.137.139): icmp_seq=3 ttl=56 time=12.3 ms 64 bytes from 58.211.137.139 (58.211.137.139): icmp_seq=4 ttl=56 time=12.0 ms 64 bytes from 58.211.137.139 (58.211.137.139): icmp_seq=5 ttl=56 time=11.3 ms 64 bytes from 58.211.137.139 (58.211.137.139): icmp_seq=6 ttl=56 time=11.5 ms
(2)、往已有文件追加内容,这个时候我们可以使用-a参数来实现:
[root@localhost ~]# ping www.itbiancheng.com | tee -a itbiancheng.log PING www.itbiancheng.com.cname.yunjiasu-cdn.net (58.211.137.139) 56(84) bytes of data. 64 bytes from 58.211.137.139 (58.211.137.139): icmp_seq=1 ttl=56 time=11.3 ms 64 bytes from 58.211.137.139 (58.211.137.139): icmp_seq=2 ttl=56 time=11.4 ms 64 bytes from 58.211.137.139 (58.211.137.139): icmp_seq=3 ttl=56 time=11.9 ms 64 bytes from 58.211.137.139 (58.211.137.139): icmp_seq=4 ttl=56 time=11.3 ms 64 bytes from 58.211.137.139 (58.211.137.139): icmp_seq=5 ttl=56 time=12.5 ms
(3)、将内容输出到多个文件,我们直接在tee命令后面直接添加对应的文件:
[root@localhost ~]# ping www.itbiancheng.com | tee itbiancheng.log www.log PING www.itbiancheng.com.cname.yunjiasu-cdn.net (58.211.137.139) 56(84) bytes of data. 64 bytes from 58.211.137.139 (58.211.137.139): icmp_seq=1 ttl=56 time=11.2 ms 64 bytes from 58.211.137.139 (58.211.137.139): icmp_seq=2 ttl=56 time=13.0 ms 64 bytes from 58.211.137.139 (58.211.137.139): icmp_seq=3 ttl=56 time=10.9 ms 64 bytes from 58.211.137.139 (58.211.137.139): icmp_seq=4 ttl=56 time=13.2 ms
(4)、忽略中断事件,这个时候我们可以使用-i参数:
[root@localhost ~]# ping www.itbiancheng.com | tee -i itbiancheng.log PING www.itbiancheng.com.cname.yunjiasu-cdn.net (58.211.137.139) 56(84) bytes of data. 64 bytes from 58.211.137.139 (58.211.137.139): icmp_seq=1 ttl=56 time=13.0 ms 64 bytes from 58.211.137.139 (58.211.137.139): icmp_seq=2 ttl=56 time=11.3 ms 64 bytes from 58.211.137.139 (58.211.137.139): icmp_seq=3 ttl=56 time=11.6 ms 64 bytes from 58.211.137.139 (58.211.137.139): icmp_seq=4 ttl=56 time=13.1 ms 64 bytes from 58.211.137.139 (58.211.137.139): icmp_seq=5 ttl=56 time=12.4 ms
