Description Miloslav Trmac 2002-09-22 18:08:03 EDT
Version-Release number of selected component (if applicable):

Sometime between 7.3 and (null), bash started to return to the start of a
line before writing its prompt, which is confusing, unexpected and discards
potentially-very-hard-to-get-again information (I have spent 10 minutes
figuring out why "rpm -q --qf '%{ARCH}' kernel" gave no output, but what
if I forget the last "\n" in last printf of a two-weeks-running program?).

Steps to Reproduce:
1. open gnome-terminal
2. insert "echo -n foo"
3. insert "echo -n 012345678901234567890123456789"

Actual Results:
[mitr@localhost mitr]$ echo -n foo
[mitr@localhost mitr]$ echo -n 012345678901234567890123456789
[mitr@localhost mitr]$ 3456789

Expected Results:
[mitr@localhost mitr]$ echo -n foo
foo[mitr@localhost mitr]$ echo -n 012345678901234567890123456789
012345678901234567890123456789[mitr@localhost mitr]$

Same in 8.0.

Note that this does occurr in gnome-terminal, xterm and konsole,
but *not* on a virtual terminal.

Note also that in gnome-terminal and the two other, backspacing
though accented characters in UTF-8 is OK, but on a virtual
terminal it moves to the left too much; this might have the same

Yes, I've seen it too and it's annoying.

It's not limited to builtins; the same happens for /usr/bin/printf for example.
It has nothing to do with PROMPT_COMMAND (unsetting it does not correct the
It is not related to $TERM (using e.g. linux as TERM does not correct the problem).
Using 'echo -n foo; sleep 2' clearly shows the cursor at the start of the line

Fixed package is bash-2.05b-12, which will shortly appear in rawhide.
