Linux tee命令

一、简介

tee以标准输入作为输入，标准输出和文件作为输出。

 

二、语法

Usage: tee [OPTION]... [FILE]...
Copy standard input to each FILE, and also to standard output.

  -a, --append              append to the given FILEs, do not overwrite
  -i, --ignore-interrupts   ignore interrupt signals
      --help     display this help and exit
      --version  output version information and exit

If a FILE is -, copy again to standard output.

 

三、实例

1）使用tee命令把标准错误输出也保存到文件

ls "*" 2>&1 | tee ls.txt
