Useful linux command

  export LD_LIBRARY_PATH=.

Source: StackOverflow

You're a little ambiguous. I expect you're probably a Linux user inside X who wants to put stuff in the X PRIMARY clipboard.

It's important to understand that bash doesn't have a clipboard. There is no such thing as “the” clipboard, because bash can run on Windows, Mac OS X, lots of other OSes, inside X, outside X, … Not to mention that X itself has three different clipboards itself. There's a wealth of clipboards you could be dealing with. Usually the clipboard you want to talk to has a utility that lets you talk to it.

In case of X, yes, there's xclip (and others).

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”.

For Windows, read /dev/clipboard (thanks glenn).

Note that xclip -selection c will send data to the clipboard that works with ^C, ^V in most applications.

  cat filename.java | xclip -selection c
