A very good point, indeed. I run Arch, so I was surprised to hear that
any sort of customization by the packager would have taken place. I
built a quick systemd namespace container with a fresh base install, and
sure enough, there extglob was not set. Upon installation of
bash-completion, however, it was.

Thanks for the help!

Good point.

  $ grep -r "shopt -. extglob" /etc/bash*
  /etc/bash_completion.d/nmh:orig_opts=$(shopt -p extglob) 
  /etc/bash_completion.d/nmh:shopt -s extglob
  /etc/bash_completion.d/libreoffice.sh:shopt -q extglob && g=1
  /etc/bash_completion.d/libreoffice.sh:test $g -eq 0 && shopt -s extglob
  /etc/bash_completion.d/libreoffice.sh:  test $g -eq 0 && 
shopt -u extglob
  /etc/bash_completion.d/libreoffice.sh:test $g -eq 0 && shopt -u extglob
  /etc/bash_completion.d/mercurial:shopt -s extglob
  /etc/bash_completion.d/subversion:shopt -s extglob

This is a configure-time option, but unless your vendor changes it, it's
off by default.  It can also be changed in a startup file or another file
that gets sourced, like bash-completion.

This isn't the case in bash as it's distributed:

$ cat x31
shopt hostcomplete
$ ./bash ./x31
hostcompleteon
$ ./bash -c 'shopt hostcomplete'
hostcompleteon
$ ./bash --version

Perhaps you should check for shopt -u extglob reversing those.

Also some vendors place a lot of customization in /etc/profile,
/etc/profile.d/*, /etc/bash_otherplaces sourced in the above.  It
might be turned on by one of those.

I see a lot of hits in the bash_completion add-on files.  Should we be
looking at:

  $ grep -r "shopt -s extglob" /etc/bash*
  /etc/bash_completion.d/nmh:shopt -s extglob
  /etc/bash_completion.d/libreoffice.sh:test $g -eq 0 && shopt -s extglob
  /etc/bash_completion.d/mercurial:shopt -s extglob
  /etc/bash_completion.d/subversion:# pattern matching enabled (use 'shopt -s 
extglob progcomp' to enable
  /etc/bash_completion.d/subversion:shopt -s extglob

This is a compile-time setting.  Your vendor probably turned this on.

imadev:~$ bash-4.3
imadev:~$ shopt | grep extglob
extglob off
imadev:~$ exit

Hi all,

When started interactively, bash sets the extglob shopt; however, that
fact seems to have been overlooked in the manpage. The behavior of bash
itself is great, but in the context of the manpage, it appears
erroneous, as it indicates that use of 'shopt' is necessary for extglob
to be enabled.

Likewise, hostcomplete seems to be disabled when bash is
non-interactive, which behavior is also not documented.

Perhaps a couple of small edits are in order?

All tbe best,
