Date: Sat, 28 Nov 2015 14:42:36 +0100
Subject: [PATCH] add comment about why the ugly one-line remote command is as
it is
In case anyone looks here for the details:
* tcsh doesn't support multi-line strings,
which is why it's a one-liner.
* tcsh doesn't do 2>&1, and fish doesn't do
'command || command' which is why we're runnig this under
sh (which is very likely to be a POSIX shell on any vaguely
Unix-like system)
* The 'cd' is there to make sure we're in the home dir, because
there was a bug report about having a cd in ~/.bashrc that resulted
in a .ssh being created elsewhere.
* the 'exec' ensures that we're not relying on anything beyond the
(hopefully POSIX) shell that's available as 'sh' on the remote system
