Is there an Environment Variable that contains the clipboard contents?

问题

Is there a Bash environment variable (say $CLIPBOARD or similar) that contains the current contents of the clipboard?

The specific example is to see the top 20 lines of a file whose path I have just copied into the clipboard.

1. Copy path with Ctrl-C
2. Switch to terminal
3. Type more, Ctrl-V

UPDATE: I'm running on CentOS 4

No, there isn't a bash environment variable. For your platform (which you don't specify) you may be able to use a command line tool like xclip or one of the many Windows utilities (google for "windows clipboard command line").

回答2:

You might look into xclip or pbcopy/pbpaste (Mac OS X).

回答3:

I don't really know exactly what you are trying to accomplish. Check out the following article and see if it helps: Remotely transferring clipboard data using netcat and bash

Update: If you are using OSX, try using pbcopy & pbpaste to copy and paste data from the clipboard.

This requires an additional command-line utility, but it looks like what you describe:

Command Line to Clipboard

回答5:

Using xclip combined with Readline bindings in Bash - a bit of a hack, but it works
