Sorry! I seem to have spoken relying on bad memory. I cannot find any
evidence of the above on my own machines.
I'd swear I'd seen changes from /bin/something to /usr/bin/something in
my etckeeper logs.

ACK.

On Daedalus

# type sh
sh is /bin/sh

On Excalibur

# type sh
sh is /usr/bin/sh

and /bin is a symlink to /usr/bin. I guess it'll just be a matter of
time until the UsrMerge folks insist on removing the symlink ... :-/

Eh, that assumes one's PATH, the places it lists and the first `sh`
found are actually sane. But then again, you should not be required to
cater to morons that are hell-bent on breaking things ;-)

I was just trying to make the point that bash is not the be-all and
end-all of shell scripting.

After two decades of bash at the command prompt, I'm giving zsh a spin
now but I still try to make my own /bin/sh scripts work with whatever
shell is providing that. Be that zsh, bash, dash, ash or even busybox
sh in an Alpine container ...

BTW, I was quite surprised to learn that zsh has been around for three
decades and then some. Actually, it seems to be only one year younger
than bash :-o

Have a nice day,
