What does the tilde (~) mean in an amigados 2.0 filename? I couldn't file any
mention of it in the Using the System Software Manual. It seems to have some
sort of wild-card properties (for example, dir ~ seems to be equivalent to dir
all, and rm #?~ would have deleted a lot more files if I hadn't done a break).
If it does have special meaning, where is it documented?

The tilde (~) is a new wildcard character used as a logical NOT operator. It should be placed before the wildcard expression you wish to NOT. For example: 1.SYS:> list ~(#?.info) will list all files not matching the pattern "#?.info" (all files that do not end with .info). I can't seem to find it in the documentation either (at least at a quick glance), but I'll check with our Documentation department on it. >UUCP: {amdahl!bungia, uunet!rosevax, crash}!orbit!pnet51!bga ================================================================================ || John J.

FINALLY a NOT operator for AmigaDOS! >For example: > >1.SYS:> list ~(#?.info) > >will list all files not matching the pattern "#?.info" (all files that do not >end with .info). My question: Does 2.0 feature some kind of NATIVE pattern matching function that can be called by programs that wish to use Amiga wildcard patterns? Something like Manx's scdir() function would be really nice. It seems awfully wasteful to have to put pattern-matching code in EVERY program that wants to use it (list, copy, delete, etc.). -- Matt *~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~* % "Progress is an up-hill battle % mrush@csuchico.edu % % against backwards compatibility." % mrush@cscihp.UUCP % % -- me % % Now: mrush@cscihp.ecst.csuchico.edu % *~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~* This is a SCHOOL!

I don't know where for sure it's documented, but the tilde is a
'not' symbol for wildcards in the 2.0 shell. Check out the parsing for
monitors stuff in the standard Startup-Sequence for 2.0. They execute
every program that *doesn't* end in .info and is in the Monitors directory.
I gave it a try, with things like copy and list, and they all seemed to
work as expected... Now all we need is an AND symbol and something like
[a-n,q].

However, Bruce asked partly because typing "delete #?~" now deletes ALL files, rather than just Emacs-type backup files (which end with ~). The escape character is an apostrophe (single-quote), so "delete #?'~" will delete all Emacs backup files. -- Stephen R.
