I was able to do
sftp yesterday to a RHEL 5.4 box (RedHat) and today I can't.
The message is
"Received message too long 778199411", and after some investigation, it was due to my RHEL box's
.bashrc having a line
echo "running .bashrc" -- or echoing anything at all, I think.
So why would printing out a line affect
sftp? It felt a bit like a design issue as printing out a line in
.bashrc works in other situations such as log in or
ssh and it is kind of hard to track down when
sftp fails for such a weird reason.
So the question is, why printing out a line cause such error and what if we still like to print out something in
.bashrc? (mainly to see when this file get sourced/executed).
