xclip (available as a package for Debian and Ubuntu) enables you
to interact with the X clipboard directly from the command-line — without
having to use the mouse to cut and paste.
Tip of the Trade: Think command line precludes using the X clipboard? Think again. xclip makes it possible to interact with it directly from the command-line — if you’re using Debian or Ubuntu.
This is particularly useful if you’re trying to get command-line output
over to an e-mail or web page. Instead of scrolling around in the terminal to
cut and paste with the mouse, screen by screen, you can use this:
command --arg | xclip
Then go to whichever graphical program you want to paste the input into, and
paste with the middle mouse button or the appropriate menu item.
You can also enter the contents of a file straight into xclip:
and again, can then paste that directly wherever you want it.
The -o option enables you to operate it the other way around:
output the contents of the clipboard straight onto the command line. So, you
could, for example, copy a command line from a web page, then use
to output it. To output to a file, use
xclip -o /path/to/file
Use the -selection switch to use the buffer-cut or one of the
other selection options, rather than the clipboard default. You can also hook
it up to an X display other than the default one (e.g., if you’re logged on as
a different user on :!) with
xclip -d localhost:1
