Also, I apparently misread the control sequences. What they look like in the light of morning is \e[0m Character Attributes = Normal (no bold, color, etc) \e[K Erase in Line to Right So now I'm thinking again that there must be something about your colorized setup that triggers use of at least the first one. But why didn't clearing the relevant environment variables change anything? regards, tom lane
