Description Joe Orton 2005-01-26 15:48:47 UTC 
This bugs me occasionally.

jorton@trash:~$ rpm -q bash
bash-3.0-25.i386
jorton@trash:~$ echo -n foo
foojorton@trash:~$

OK so far; now type "bar" then hit Ctrl-a then Ctrl-e 

jorton@trash:~$ barbar

the line is redrawn from column 0 but is not cleared first.

bug or feature?
Comment 1 Tim Waugh 2005-01-26 16:06:08 UTC 
Feature.  Bash either has to assume that it's starting on the first column
(leading to the behaviour you see), or make sure that it's starting on the first
column by emitting '\r' before the prompt.

In the latter case (which was the behaviour for a short while) you would not see
the output of the echo command at all, since it would be overwritten.
