将多个命令的输出重定向到文件 [英] Redirect outputs of multiple commands to a file

问题描述

例如，我同时在Linux Shell中运行多个命令

I'm running multiple commands in my Linux shell at the same time, e.g.

echo "Line of text 1" && echo "Line of text 2" && complexthing | xargs printf "complexspecifier"

我想将所有输出重定向到file1.我知道我可以在每个单独的命令后添加>file1，但这似乎很庞大.我该怎么办?

I want to redirect all output to file1. I know I can add >file1 after each individual command but this seems bulky. How can I do this?

推荐答案

exec >file1   # redirect all output to file1
echo "Line of text1"
echo "Line of text2"
exec > /dev/tty  # direct output back to the terminal 

或者，如果您使用的计算机没有/dev/tty，则可以执行以下操作:

Or, if you are on a machine that doesn't have /dev/tty, you can do:

exec 5>&1 > file1  # copy current output and redirect output to file1 
echo foo
echo bar
exec 1>&5 5>&-  # restore original output and close the copy
