Hello,

I receive this random error once in a while.

Hi, Joe! Thank you for your report.

Sorry, I have not seen this before…
How about this patch? (This is mostly guesswork though)

Hello Takeshi,

Thanks for the patch. I applied it. Can you please add this patch to the pu
branch? The gentoo build uses that branch and I do not want to lose the
patch if I reinstall.

This is the definition of my which command:

which
which () {

printf '\e[?7t'
builtin which "$@" && builtin type "$@" && whereis "$@" &&
file $(builtin type "$@" | awk '{print $3}') 2> /dev/null

}
which is a shell function
which: /usr/bin/which /usr/share/man/man1/which.1.bz2

Please let me know if you need more details.

Thanks

Hi, Joe! Thank you for reporting back!

I can reproduce the error now; the $IFS is the cause.
I change the which function's IFS="$(print '\n\t')" to local IFS=… then this problem goes away.

Some auto-fu's codes are depending on IFS value :(
I will fix this for some time.

For now, please handle it with editing which function's definition.
Sorry for the inconvenience.
