     In case of X, yes, there's xclip (and others). xclip -selection c will send data to the clipboard that
     works with Ctrl-C, Ctrl-V in most applications.

     If you're trying to talk to the Mac OS X clipboard, there's pbcopy.

     If you're in Linux terminal mode (no X) then maybe you need to look into gpm.

     There's also GNU screen which has a clipboard. To put stuff in there, look at the screen command "readreg".

     Under Windows/cygwin, use /dev/clipboard or clip for newer versions of Windows (at least Windows 10).
