Somewhat of a misnomer, this extension adds two menu entries to the
selection popup that allows one to run external commands to store the
selection somewhere and fetch it again.
We use it to implement a distributed selection mechanism, which just
means that one command uploads the file to a remote server, and another
The commands can be set using the URxvt.remote-selection.store and
URxvt.remote-selection.fetch resources. The first should read the
selection to store from STDIN (always in UTF-8), the second should provide
the selection data on STDOUT (also in UTF-8).
The defaults (which are likely useless to you) use rsh and cat:
URxvt.remote-selection.store: rsh ruth cat >/tmp/distributed-selection
URxvt.remote-selection.fetch: rsh ruth cat /tmp/distributed-selection
