Hi,

I'm using Mac 10.6.3. In my .bash_profile, I have some directives
that mount a remote directory, such as

mount_sshfs test(a)remotehost:/opt/catalina/qa /opt/catalina/qa/

However, if I open multiple terminal windows, this command is run
again, the error message "directory is already mounted" appears, which
makes sense. How can I prevent the command from being run if the
directory is already mounted?

Thanks, - Dave

I don't use bash, nor do I have mount_sshfs on my system, but you can
redirect output to standard error to the bit bucket (null device)
instead of the screen:

mount_sshfs ... 2> /dev/null

if mount | grep -q /opt/catalina/qa
then :
else mount_sshfs test(a)remotehost:/opt/catalina/qa /opt/catalina/qa
fi

Hey Barry, The "else" branch is always executing, regardless of
whether I have anything mounted. - Dave

Could you post the output of the "mount" command when you don't have
anything mounted? Maybe there's something unexpected that's matching
the grep.

P.S. Please don't quote signatures.
