Hello, Walter.
The thing with {...} is they're shell expansion operators. You will need a
shell that supports them, such as bash or ksh (some versions). The old
bourne shell won't cut it.
You can test for it using a simple echo, no need to bother yourself with mkdir:
$ echo a{b,c,d}
ab ac ad
It will only do the job as a bareword, that is, you can not enclose it in
quotes of any kind. Braces also will not be expanded when you forget to
close the structure with a closing brace (can be tricky when you are nesting
braces).
For more information, see "Brace Expansion" in your shell's manual.
Kind regards,
