Does putclip exist for Linux? i.e. can stdout go to the clipboard?

[KenJackson]

The Cygwin environment (a Linux-like environment for Windows) has a command named putclip.exe, which copies it's stdin to the Windows clipboard.

I would love to be able to make the output of a GNU/Linux command in a terminal go directly to the X clipboard so I can paste it into the message editor right here, or into another app, such as a text editor.

Imagine this:
$ grep ip_forward /etc/sysctl.conf | putclip

Then in the message editor, CTRL-V pastes the result.
Can it be done?

There is a program called xclip that will do what you are asking.

EXCELLENT!

I've been wishing I had something like xclip for years. I finally got around to asking.
