Public bug reported:
Binary package hint: base-files
I noticed that commands that are executed more than once in a root shell
also appear more than once when using the arrow keys. That is clearly
not desired behaviour. The default /root/.bashrc says this:
# don't put duplicate lines in the history. See bash(1) for more options
#export HISTCONTROL=ignoredups
The bash skeleton in /etc/skel/.bashrc says:
# don't put duplicate lines in the history. See bash(1) for more options
# don't overwrite GNU Midnight Commander's setting of `ignorespace'.
export HISTCONTROL=$HISTCONTROL${HISTCONTROL+,}ignoredups
# ... or force ignoredups and ignorespace
export HISTCONTROL=ignoreboth
This seems better. Googling around I found out that /root/.bashrc is copied
from /usr/share/base-files/dot.bashrc (is that right?). The lines in question
have been inserted into that file five years ago with the comment “sync with
bash
skeleton files”, where the export statement is commented out:
http://bazaar.launchpad.net/~ubuntu-branches/ubuntu/lucid/base-
files/lucid/revision/2/share/dot.bashrc
So maybe the “sync” step needs to be repeated. Related: bug 228747
