SSH parameter to ignore .bashrc script

Question

I have a server which executes this line in .bashrc when it starts: /bin/watch ~/checker.bash. Which, as expected, watches that command upon server start.

I also have a client which logs into that machine, but I do not want the client's sessions to execute the same command from the .bashrc.

I have looked at AcceptEnv for passing env vars, though it requires configuration of the server, which I want to avoid.

I also don't want to have two different user accounts for different .bashrcs.

Is there another angle to approach this from?

Answer 1

Two ways:

Don't use bash for this session, try dash (or /bin/sh):

ssh 127.0.0.1 /bin/dash

Use bash with command options to disable processing startup files:

ssh 127.0.0.1 "bash --noprofile --norc"

Answer 2

you could activate parts of your .bashrc only if it is not invoked via ssh.

e.g. something like:

# within an SSH-session, ${SSH_TTY} will be set
if [ "x${SSH_TTY}" = "x" ]; then
  /bin/watch ~/checker.bash
fi

Answer 3

You can substitute the line /bin/watch .... with

 if ps ax | grep /bin/watch | grep -v grep  > /dev/null 2>&1
 then
    echo "Nothing to do"
 else
    /bin/watch ~/checker.bash
 fi

or some such thing.
