Maybe the fact that BSDs don't use bash as default shell?

it is available from the install script on mine.

Still no reason for it to futz the output.

Any chance of elaborating on it?

Among other things -- are you sure you are using bash? The
/bin/sh in my OBSD 6.0 is linked to:

26004 -r-xr-xr-x 3 root bin 554K Jul 26 2016 ksh*
26004 -r-xr-xr-x 3 root bin 554K Jul 26 2016 rksh*

To find out for sure, start with this:

which sh (if using tcsh as your personal shell)
(or "ls /bin/sh" to make sure that is there)

Once you are sure that sh is in /bin, then this:

ls -i /bin/sh
and you should get something like this:

26004 /bin/sh

then follow that with

"ls -i /bin | grep 26004" (or whatever number the previous command gave
you), and you will see a listing of all the names linked to the
same file (-i gives you the inode number):

and get something like:


======================================================================
# ls -i /bin | grep 26004
26004 ksh
26004 rksh
26004 sh
======================================================================

In other words -- all the names which are linked to that one
file.

Now -- did you actually install bash from the packages? It is
not installed by default. And based on the above, if you ran

/bin/sh /path/to/my/script

you would be trying to run a bash script in the Korn shell (/bin/ksh),
and that and bash use different extensions over /bin/sh.

You have to download it from the OBSD packages site for your
cpu, and then install it. For OBSD 6.0, a check through there finds
this as the install for bash:

bash-4.3.46.tgz

For that matter -- which linux? For the nearest one to reach,
(Ubuntu 18.04.2), the default shell is dash, not bash, nor ksh, nor
zsh).

Good Luck,
DoN.
