Check your /etc/profile for control characters, and how to suppress them.
Eg.stty erase '^H'

Hi Jay,

^? is the representation for the DEL character (0x7F). This usually happens when someone has their backspace key misconfigured, they think that they are erasing characters when in fact they are adding DEL's.

There are several ways of deleting them, one is as follows:-

Set $X to be a DEL character:-
X=$(print "\0177")

Then you can use $X in ll and rm commands:-

ll *$X*
rm -i *$X*

The above will list and offer to remove any file which contains a DEL character.

Regards,
John

to me the backspace has been typed many times to cancel something wrong written by keyboard.
To avoid this in your .profile or in /etc/profile set

stty erase '^H'
