Operating Systems SCO Command line overwrite
# 8  
Telling us that you're using /bin/sh without telling us what operating system you're using doesn't really tell us all that much. On many systems /bin/sh is a link to another shell (e.g., bash, dash, or ksh). On at least one system /bin/sh is an honest to God 1980's Bourne shell. (When starting a thread on unix.com, please always tell us what operating system and shell you're using. Having some idea about the environment you're using will help us give you answers that stand a better chance of working in your environment.) Unfortunately, I have no idea what shell underlies /bin/sh on SCO systems.

On systems where /bin/sh is a link to a POSIX standards-conforming shell, you could try issuing the command:
Code:
set -o vi

to turn on vi command line editing mode. Once that has been done, if you hit the <escape> key while entering a command, you can use the usual vi editor commands to erase, replace, insert, and substitute text on that line and then hitting the <enter> or <retturn> key will submit that line to the shell for processing.

This means that your terminal and the system disagree on what character a backspace is.

What is your terminal?

SCO UNIX 3.2.4.2 does everything in command prompt(/bin/sh). No desktop.

Yes -- but what is your terminal? A permanently wired keyboard and monitor directly attached to the SCO machine? An instance of PUTTY running on Windows? A smartphone app? A printing teletype circa 1977? A generic beige VT100 attached to the serial port? Some sort of web gateway? Other?

Monitor and keyboard at the SCO machine. Putty on Windows 10 connecting over the network. QVTterm on a Windows 2000 VB image.
All 3 have the same results.

Thank you. Try stty erase funny-character, where funny-character is the strange char you get hitting backspace. Just a temporary solution but if it works, that means SCO is configured to use the wrong kind of terminal.

I had myself screwed up. Its not the backspace that puts in special characters.
Its when you arrow left.
Code:
# cat /esc/hosts

Like if I arrow over to replace the s with a t
