Are there any shells for the amiga (either commercial or freely redist.)
that actually do the wildcard expansion, rather than the program
having to do it? In other words, if I have a directory containing:
foo.1 foo.2 foo.txt
and I have written a SAS/C program which simply scans argc and argv
and prints out all its command line arguments (call it arg, say) and
I do:
> arg foo.? *.txt
in that shell, then
foo.1 foo.2 foo.txt
will be the output of my program.
Are there any such beasties?

It is a UNIX Korn Shell clone. There is one limitations however....when passing parameters to commands, AmigaDos (1.3 and below) limits you to 256 characters on the "command line". When executing SKsh's built in commands, that is not a limitation. Check it out, it works great!!! ---------------------------------------------------------------------------- These words be mine.

In other words, if I have a directory containing: >foo.1 foo.2 foo.txt Well, I use the WShell v1.2 with an ARexx program to do what you are asking about and more. See the header below: /* * !.rexx ... processes '?', '[]', '*', '.', '..', '~' and '/' * and `backtick` evaluation * Does filename globbing and minimal UNIX file system emulation * Started: 9/4/89 * Updates: 10/22/89 1/9/90 * Last update: Tue Feb 20 00:51:27 1990 * By Loren J. Rittle */ This ARexx program is inserted into the WShell prompt so that my program gets to read in a command line and process it before passing it on to the WShell. I better explain what I mean by `inserted into the WShell prompt,' Bill Hawes, the creator of ConMan, WShell and ARexx, was thinking ahead (and still is according to some tidbits I heard on BIX recently...) when he designed the WShell. He (at least the last time I spoke with him) is opposed to doing filename expansion in the shell at least for AmigaOS, but he provides a hook to allow a user written program to preform any type of preprocessing to a command line that is typed from a prompt. Actually the hook was designed to allow one to run a program to update a titlebar message, check for mail, etc and it just so happens to have been designed in such a way as to allow for my use also :-). !.rexx requires ARexx v1.1, WShell v1.2, ConMan v1.3c, rexxarplib and ARP (hehehe). It only runs at an acceptable speed on an accelerated machine. In about 2 weeks it will have CSH type history, because I just got the inspiration to add it after using UNIX machines for the last semester in a VLSI class. The WShell via ConMan already support a very nice history mechanism, but every once and a while I think about how nice the CSH type history is. You (or anyone) can get it from me once I clean it up a bit and add some documentation. !.rexx also *needs* to support a better quoting mechanism as right now there are some things that can't be passed through... As you can see, there are some problems, but it has been working nicely (i.e. providing everything mentioned in the header above) for myself and about four friends. Loren J.
