Run text file as commands in Bash
提问by Blainer
If I have a text file with a separate command on each line how would I make terminal run each line as a command? I just don't want to have to copy and paste 1 line at a time. It doesn't HAVE to be a text file... It can be any kind of file that will work.
如果我有一个文本文件，每行都有一个单独的命令，我将如何让终端将每一行作为命令运行？我只是不想一次复制和粘贴 1 行。它不必是一个文本文件......它可以是任何可以工作的文件。

You can use something like this:
你可以使用这样的东西：
for i in `cat foo.txt`
do
sudo $i
done
Though if the commands have arguments (i.e. there is whitespace in the lines) you may have to monkey around with that a bit to protect the whitepace so that the whole string is seen by sudoas a command. But it gives you an idea on how to start.
尽管如果命令有参数（即行中有空格），您可能需要稍微调整一下以保护空格，以便将整个字符串视为sudo命令。但它让你知道如何开始。

Execute
执行
. example.txt
That does exactly what you ask for, without setting an executable flag on the file or running an extra bash instance.
这正是您所要求的，无需在文件上设置可执行标志或运行额外的 bash 实例。
