在终端上打印并同时写入文件? [英] Print on terminal and into file simultaneously?

问题描述

我有一个可以捕获一些数据的shell脚本.我想将结果打印到文件中，但是这样做会阻止结果显示在终端上.有没有办法既可以在屏幕上打印结果，又可以写入文件. 预先感谢.

I have a shell script that greps some data.. I want to print the result into a file, but doing that prevents the result being displayed on the terminal. Is there a way that can both print the result on the screen and also write into a file. Thanks in advance.

推荐答案

将输出内容放置到 tee 命令.

Pipe your output to the tee command.

示例:

[me@home]$ echo hello | tee out.txt
hello
[me@home]$ cat out.txt 
hello

请注意，echo的标准输出已打印并写入thr tee命令指定的文件中.

Note that the stdout of echo is printed out as well as written to the file specified by thr tee command.
