Description Doktor Notor 2010-03-13 13:56:13 UTC
E.g., if I type cd /usr/portage/distfiles into a subshell in , the folloging will get logged:

 cd "`printf "%b" '\0057'`"
 cd "`printf "%b" '\0057usr'`"
 cd "`printf "%b" '\0057usr\0057portage'`"
 cd "`printf "%b" '\0057usr\0057portage\0057distfiles'`"
 cd "`printf "%b" '\0057'`"

Have had this problem for ages, valid with any app-misc/mc version incl. the latest masked 4.7.1. Happens not always, usually doesn't happen if I press Enter before typing into the subshell. 

Extremely annoying, would at least welcome a hint how to make bash not log such crap.

Just in case, but this is Gentoo-standard anyway:

$ echo $PS1
\[\033[01;32m\]\u@\h\[\033[01;34m\] \w \$\[\033[00m\]

Well, I'm seeing something alike, but it seems quite random.

Good to know I'm not alone. Upstream stuff related to shell history:

I guess I should file one about this there are well, it's not Gentoo-specific since I managed to reproduce this on FreeBSD as well. Though, I'd like to find out when exactly this happpens at least first before filing something upstream.
Comment 3 Doktor Notor 2010-03-17 09:36:16 UTC
Oh well... meanwhile, sticking 

export HISTIGNORE='cd "\`printf*'

into $HOME/.bashrc seems to kill most of the junk. Since this clearly isn't anything Gentoo-specific, I'm closing the bug as UPSTREAM. Clean solutions still welcome. :)
Comment 4 Doktor Notor 2010-03-17 12:41:37 UTC
Ok, so... for those scratching their head about their clobbered history, this is the outcome :)
