make-timonel.sh under Linux

[prandeamus]

"make-timonel-sh" doesn't execute under Linux (more properly when I use it from bash shell)

./make-timonel.sh: 40: ./make-timonel.sh: function: not found
(then the "Usage text"
./make-timonel.sh: 79: ./make-timonel.sh: Syntax error: "}" unexpected

Problem seems to be line 1 hash-bang

#!/bin/sh

If I change this #!/bin/bash, it works

I suspect that your development environment regards bash and sh as functionally equivalent. but for me sh and bash are different executables. Lordy, lordy, I love Unix but how many shells can one operating system need? The documentation says that sh is synonym for dash, but that bash is different. Presumably my sh (dash) doesn't like your function syntax.... argggh. Workaround for me is to edit line 1. as noted above. I'm not really sure what linux best practice is here, and if there some incantation which always picks the right shell? I didn't want to submit a PR not knowing best practice.

As a sanity check, the sample output for ./make-timonel.sh tml-t85-small timonel 13 1B80 1 false is attached below.

Ignore format messup - output of the script was interpreted as markdown.

I couldn't come to a definitive conclusion on what the correct hash-bang should be in this case.

I did several tests with "make-timonel.sh" on Fedora and CentOS and using #!/bin/sh or #!/bin/bash seems to be indistinct for this script. Maybe on non-Red Hat-like Linux distros, is not like this.

Given that #!/bin/bash also works fine for Git Bash on Windows, I'll use it everywhere, so this problem, for the moment, could be considered solved this way.

That sounds good - for reference I'm using a Ubuntu derivative it belongs to the debian family.
