How do I paste multi-line bash codes into terminal

问题:

I need to paste a multi-line bash code into terminal, but whenever I do, each line gets run as a separate command as soon as it gets pasted.

回答1:

Try putting \ at the end of each line before copying it.

I'm really surprised this answer isn't offered here, I was in search of a solution to this question and I think this is the easiest approach, and more flexible/forgiving...

If you'd like to paste multiple lines from a website/test editor/etc, into bash, regardless of whether it's commands per line or a function or entire script...simply start with a ( and end with a ) and Enter, like in the following example:

If I had the following blob

function hello {
    echo Hello!
}
hello

You can paste and verify in a terminal using bash by:

1) Starting with (

2) Pasting your text, and pressing Enter (to make it pretty)...or not

3) Ending with a ) and pressing Enter

Example:

imac:~ home$ ( function hello {
>     echo Hello!
> }
> hello
> )
Hello!
imac:~ home$ 

The pasted text automatically gets continued with a prepending > for each line. I've tested with multiple lines with commands per line, functions and entire scripts. Hope this helps others save some time!

If you press C-x C-e command that will open your default editor which defined .bashrc, after that you can use all powerful features of your editor. When you save and exit, the lines will wait your enter.

If you want to define your editor, just write for Ex. EDITOR=emacs -nw or EDITOR=vi inside of ~/.bashrc

In addition to backslash, if a line ends with | or && or ||, it will be continued on the next line.

回答5:

Add parenthesis around the lines. Example:

$ (
sudo apt-get update
dokku apps
dokku ps:stop APP # repeat to shut down each running app
sudo apt-get install -qq -y dokku herokuish sshcommand plugn
dokku ps:rebuildall # rebuilds all applications
)

Another possibility:

bash << EOF
echo "Hello"
echo "World"
EOF

回答7:

To prevent a long line of commands in a text file, I keep my copy-pase snippets like this:

echo a;\
echo b;\
echo c

回答8:

Try this way:

echo $( 
    cmd1
    cmd2
    ...
)

iTerm handles multiple-line command perfectly, it saves multiple-lines command as one command, then we can use Cmd+ Shift + ; to navigate the history.

回答10:

Try

out=$(cat)

Then paste your lines and press Ctrl-D (insert EOF character). All input till Ctrl-D will be redirected to cat's stdout.
