When using the up or down issue I sometimes get an issue where some of the previous commands text appears in front of my actually typing. It does not affect anything when I hit enter but it is very annoying having text appear at the beginning that appears to go with the rest. Any idea what is going wrong?

command line

Side info: Connected using PuTTY on a Windows 7 machine, connecting to a Linux box.

What is the [518]%? Is that your [prompt]) or is that some kind of progress indicator from a running program? What is your shell? – terdon Apr 17 '13 at 17:58
@terdon Tells how command number you are on, and you can check the history of your commands. I believe this is a Linux box (running Ubuntu). – Fogest Apr 17 '13 at 18:04
@terdon My shell I guess is using bash? 6930 pts/29 00:00:00 bash – Fogest Apr 17 '13 at 18:06
Possibly the TERM environment variable is set incorrectly. – Scott Apr 17 '13 at 22:42
@Scott Must this be changed by a system admin, or can this be changed by myself from a normal ssh account? – Fogest Apr 18 '13 at 2:17
