I like `xsel --clipboard` which Does The Right Thing by automatically deciding if it should copy or paste. # Paste clipboard into command. xsel --clipboard | grep foobar # Copy into clipboard grep foobar somefile.txt | xsel --clipboard # Transform clipboard. xsel --clipboard | tr A-Z a-z | xsel --clipboard I find this so useful that I have it aliased to `c`.
