terminal input buffer size

It's probably a problem with that command. Tools that expect user input typically don't expect an unlimited stream of data. 1024 is a reasonable limit in such cases.

See if the tool has an option to read data from standard input. Then, you can use the "pbpaste" command with a pipe to feed the contents of your clipboard as standard input.

The issue happens when I paste.

So don't paste. Do this instead:

pbpaste | base64

The back tics are old school. Once you have text on the clipboard, you might consider something like this to send the text on the clipboard into base64:

base64 <<<$(pbpaste) > output.txt.b64

Hello,

In terminal I run a command that waits for a user input, for example `base64`. I paste the text, but I can only paste up to 1024 symbols. Where is this limit set and how I can increase it?

Thanks.

Not sure I get it...

if this is scroll back limit you can change that is Settings...

I do see quite a bit of base64 Q&A:

Just use the example I provided. Simpler to deal with and does not bump up against potential Terminal command-line length issues.

Anything that you paste from the clipboard using ^v must be deliberately enclosed in double quotes when using the <<< input operator — but why deal with the horrible mess that creates in the Terminal window?

@etresoft

actually, the issue happens also when I type the text.

I run

base64

and then type text, at 1024 symbols terminal starts beeping and does not accept any more input.

Yeah. I got that. You'll need to find another solution. You've been offered a couple of similar solutions. It's on you to pick one of them.

That's what I told you in my first reply. No such thing exists. By logical deduction, you can't change the behaviour of what doesn't exist.
