Michael: Marianne, do you know 'xx' from the house of F*EX?
Marianne: No, Michael, what can we do with it?
Michael: Transfering files even faster and smartly
as with fexsend!
Marianne: NO, Michael, is it possible!? This is UNBELIEVABLE!!
I have n accounts on y hosts, which have different names
and rights, including administrative accounts like root or
webmaster.
With them I want to swap files "on the fly".
Mostly I cannot use scp or sendfile because of router firewalls and port
restrictions, on which I do not have influence.
Even worse it gets with DHCP and NAT.
With fexsend for UNIX there is already a quite good
solution, but not that fast and smart.
Within fexsend comes xx (as
symlink). This provides an extremly easy file transfer, an internet clipboard!
On Windows you can install Cygwin to use xx.

But what if one does not have fexsend initialized on the receiving side (no F*EX ID)?
Then simply copy (with mouse) the output from fexsend -I from
your local to the remote shell account! Example:
framstag@tandem:~: fexsend -I export FEXID=U2V0ZWMgQXN0cm9ub215Cg==;history -d $((HISTCMD-1))
Note: xx does always compress (using gzip)!
xxx: extended xx Internet clipboardxxx is an extension of xx
and stores files or pipe data with versioning.
Example pipe data upload:

xxx -u gives you shell code for copy&paste for another user
which generates a bash upload function (uses curl).
xxx -x gives you shell code for copy&paste to another host
which installs xxx in /tmp/
and it copies your FEXID, which you need for authorization.
With these commands you can use your F*EX clipboard on any UNIX host in the Internet! And with Cygwin on Windows, too!
To install the F*EX clients see the FAQ.
