使用 Bash 打开并将数据写入文本文件? [英] Open and write data to text file using Bash?

问题描述

如何在 Linux 中通过 shell 脚本自动将数据写入文本文件?

How can I write data to a text file automatically by shell scripting in Linux?

我能够打开文件.但是，我不知道如何向其写入数据.

I was able to open the file. However, I don't know how to write data to it.

推荐答案

简短的回答:

echo "some data for the file" >> fileName

但是，echo 在理想情况下不会处理行尾字符 (EOF)方式.所以，如果你要追加不止一行，用 printf 来做:

However, echo doesn't deal with end of line characters (EOFs) in an ideal way. So, if you're gonna append more than one line, do it with printf:

printf "some data for the file
And a new line" >> fileName

>> 和 > 运算符对于重定向命令的输出非常有用，它们可以与多个其他 bash 命令一起使用.

The >> and > operators are very useful for redirecting output of commands, they work with multiple other bash commands.
