FIND dos command

Questions
1) I do have a lot of archives in the lha: drawer, some with filenotes pointing to the download URL, others with an empty filenote

Find lha: COMMENT ~%

does not give any output.
I would have expected to get all files with a non-empty file note.

2) i did not find a way to restrict the search to the current directory, (no recurrent search in the subdirectories . If this is impossible is this in the pipeline for a new version?

3) What are the BETWEEN and the WITHIN keywords for ?

1) try ~(#?)

Why do you think that % is a wildcard?


Edit: sorry, ~(#?) will only list those without a comment. Try ?#? to get those with at least one character.

according to RKRM % stands for the NULLL string

Find COMMENT ~(#?) seems not even to list the ones without a filenote ( or all the filenotes i recognise as empty would contain some blanks only - i doubt that is the case, anyway going to look at it lore closely)

?#? works OK, thanks

It's also listed in the AmigaDOS book that came with my A4000. I don't have the A4000 anymore but I kept the books. I don't think I've ever seen it used other that in an example in the Amiga Guru Book. The example is: foo(%|.info) which would match foo or foo.info. Did you try ~(%) to see it makes a difference?

This works as well: foo(|.info)
I never needed to put a % sign in there.

@xenic

find COMMENT ~(%) does not work : not a sigle file recognized. Probably % is interpreted s any other character

Or, since filenames cannot be empty, the wildcard matching doesn't like empty strings either.

@thematic
we are talking about comments where empty strings are fairly commond

There is an other difference to be noted with the normal pattern matching eg used by the list command:
a#? in Find is the same as
#?a#? in List command (normal amiga pattern matching)

If the FIND way of pattern matching is where AmigaOS4 is going a character identifying the start of the string (^ caret in python) is lacking.
OS4 developers should then go all the way and also define a character symbolizing the end of the string

Hmm... I wonder why nobody here tried the ? wildcard.

"find COMMENT ?" finds only files with at least one character within the comment field. One could extend this pattern with several other patterns contained within brackets, I would suppose.
