Linux Server Fix: Backspacing on OSX Terminal Should Not Be Interpreted as Delete

I have accounts on a number of Linux machines that I ssh into from my
MacBook, using Terminal. On some — but not all — of them, I’ve found that
if I run screen after connection, the backspace key is interpreted as
a delete (giving an error if the cursor is at the end of the line), and I have
to use Ctrl-H to backspace. After poking around a little online, I found
several possible ways to fix this.

Change the $TERM Setting of Your ssh Session Once Logged On

Tip of the Trade: Backspace and delete may seem the same, but often they are not. This is particularly problematic when using Screen on OSX Terminal. Here are three easy fixes.

export TERM=xterm; screen

You can make this permanent by either putting the $TERM setting
into your .bashrc or aliasing screen.

alias screen="export TERM=xterm; screen"

However, in the first case, your terminal isn’t identified as
xterm-color, which may affect other settings (such as your bash
prompt). This isn’t a problem in the second case (screen sets
$TERM to ‘screen’), but it’s a bit of a hack.

Copy the Terminfo File for xterm-color From Your Mac Onto the Remote Linux Box

scp /usr/share/terminfo/78/xterm-color	[email protected]:.terminfo/x/

Thank you MacOSXHints
for this suggestion
. Log back in, run screen, and all should be
well. This shouldn’t cause problems if logging in from a non-Mac OS X

The Quickest Option

In the Advanced tab of the Terminal Preferences menu, there’s an option to make backspace send Ctrl-H. Curiously, however, it’s only for screen that you must tick this; backspace works fine with regular ssh.

So far I’ve preferred the second option, as it feels to me like a cleaner fix. The third option does have the advantage that you need only do it once (on your local machine), not once per remote account.
