Sorry, not sure that the config is an option in gmail, but i'll do it by hand.

Attached is the file listing the bash version as 3.0-14

adding the trailing slash produces:

PS1='\[\033]61;\u@\h:\w\007\]\u@\H \W>\[\]'
v468929@TRD-CAX40JXD ~>>

again, if i do a couple of tab complete button presses that clears the
extra entry:

v468929@TRD-CAX40JXD ~>>ls db2Mgr.
db2Mgr.C  db2Mgr.h
v468929@TRD-CAX40JXD ~>ls db2Mgr.
