Backspace giving ^?^?

How can I get rid of the "^?^?" characters when using my backspace key? I am using /sbin/sh...

Thanks

Type "stty erase ^?", where the ^? is the backspace key.

You can add it to your profile too.

OR, you can check your terminal util and see what it is using for DEL or BACKSPACE, and change it to the right one.

What's your enviroment ie do you see this on the system console, under Xwindows/CDE, via a dtterm,xterm other vt emultor ? Are you using a PC ?

what's the output from stty -a ->

erase ^H intr ^C kill ^U start ^Q stop ^S swtch ^@ susp ^Z

What behaviour are you after ...Backspace = Delete
?

ps Sorry 4 all the Qu's

Hi Mike,

Try this

stty erase "^?"

^ --> Shift + 6
? ---> ?

you can also try

stty erase "^H"

If it works, set the stty throuh your .profile

Hope this helps.

Thanks

export TERM=hp

stty erase [backspace]
will set it right as mentioned.

Mike

set your erase character through stty

stty erase

You should get rid of the problem.

Just a suggestion, but you might want to do this in your .profile, i.e.:

if [ "$TERM" = "" ]
then
eval ` /bin/tset -s -Q -m ':?hp' `
else
eval ` /bin/tset -s -Q `
fi

if [ "$TERM" = "hp" ]
then
stty erase ^?
fi

Do you perhaps use the Delete key instead of the Backspace key? The Delete key gives the behaviour which you describe. Backspace is octal code 10, while Delete is octal code 177.
