pause command line utility

[Dmitry Bogatov <KAction@gnu.org>]

Hello!

I need pause utility to keep gpg-agent in foreground:
gpg-agent --use-standard-socket --daemon ./pause

Something like following C program:

	#include <stdio.h>

	int main (void)
	{
		return pause();
	}

Is there any standard utility for it?

`apt-file find pause' returns only 'pauseme', something related to Tk
window manager. Web search also did not helped. Neither did `dpkg -L
coreutils'.
