`bash: $grouplist: ambiguous redirect`

[shivams]

I am trying out bash-it using its Docker container, on my Ubuntu 16.04. All works fine, except when I ask for help on plugins using bash-it help plugins, it starts throwing this error:

bash: $grouplist: ambiguous redirect

This error is printed continuously on the screen for a while, and then finally I press Ctrl-C after which it shows:

[3]+  Stopped                 for gfile in $(cat $grouplist | sort | uniq);
do
    printf '%s\n' "${gfile##*.}:"; cat $gfile; printf '\n'; rm $gfile 2> /dev/null;
done | less

@ellerbrock Any idea about this one?

[Maik Ellerbrock]

@nwinkler sorry for the late reply, baby coming the next days :)

i tried like @shivams mention to run the command bash-it help plugins inside the container and got the same error message. after a bit research i found what is causing the problem here: https://github.com/Bash-it/bash-it/blob/master/lib/helpers.bash#L384

mktemp /tmp/grouplist.XXXX => mktemp: Invalid argument

a fix would be to add 2 more X: mktemp /tmp/grouplist.XXXXXX

Bash Information:

i start my base image from the latest official bash version (4.4.12(1)-release) from: https://hub.docker.com/_/bash/

bash --version

Not sure if this have something to do with changes in Bash 4.4 for mktemp?
https://lists.gnu.org/archive/html/info-gnu/2016-09/msg00012.html

rr. Bash now uses mktemp() when creating internal temporary files; it produces
    a warning at build time on many Linux systems.
