[TriLUG] SCP acting funny

[Brian A. Henning]

Ah, yes, that definitely seems to be it exactly..  Any output from a bashrc
appears to confuse scp..  Apparently it closes the connection after it sees
a line-feed character in the stdout stream.  Not being a wisened programmer,
I can only speculate as to why it was coded that way.

At any rate, I do not wish to forfeit the output of my ~/.bashrc if I can
avoid it.  Is there any sort of condition I could check to conditionally
branch around the output only when scp is making the connection?  Like some
environment variable or perhaps the parent process that spawns the instance
of bash?  Something akin to this pseudo-shellcode:

if [remote_command ne "scp"]; then
  /usr/local/games/fortune;
  /usr/bin/uptime;
fi

Thanks everyone that offered suggestions.

Cheers,
~Brian
