Hello,
When I try to setup a HISTFILE to something different from /root/.ash_xxxx it
creates a weird file under / which is the history file.
For instance, easy to reproduce:
$ docker run -it --rm busybox sh
/ # busybox --help | grep ^BusyBox
BusyBox v1.33.0 (2020-12-29 22:13:53 UTC) multi-call binary.
BusyBox is copyrighted by many authors between 1998-2015.
/ # ls
bin dev etc home proc root sys tmp usr var
/ # HISTFILE=/tmp/foo
/ # ls
bin dev etc home proc root sys tmp usr var w??
/ # cat w*
ls
/ #
In fact I tried to disable history by setting HISTFILE=/dev/null and noticed this behavior (it was in a alpine image which is using
busybox ash as shell script).
I have checked the source file but did not see obvious problem.
Thanks for your support.
Kind regards.
Olivier
