Slackware Line Numbering

[Jefferson Kirkland]

I have an issue with a new install of Slackware 8.0.  Upon logging in, I 
notice that before the PS1 prompt, there is a number.  Every time I enter a 
command and hit enter, the number increases.
Is there anyone who knows how to remedy this so that the line number does 
not appear?  I have already tried defining my own PS1 prompt and the line 
numbers are pretty resilient.  Any help is greatly appreciated.

Thank you!
