Subject: [Caml-list] Wildcard expansion/command line
Date: Tue, 14 May 2002 08:50:59 +0100 [thread overview]
Message-ID: <20020514075059.30862.qmail@operamail.com> (raw)
Hello,
This is my second time at the list. Feel good to be back :) Hope all of you are well!
I have a question right away. It might not (probably not) be a Ocaml related question but I'll give it a shot!
I write a program that is invoked from the command line. All well, but when I was starting to make my program deal with wildcards I realized that the ocaml program gets its command line arguments expanded (if wildcards are used). I have included an example at the bottom of my mail to clarify if it is unclear what I mean.
Now, is this done by the OS or the shell? How do I controll this behaviour? Of course I can enclose any arguments within "" and expand any wildcards manually - but I figured, if programs like 'ls' don't have to use quotes, why should I.
So, how does it work?
regards
Jens
Example: If a directory has two files m1.txt and m2.txt, and my ocaml program (here called myprog) is invoked with wildcards it would behave something like this:
Example call Command line arg within my program
./myprog m* -> Sys.argv.(1) = "m1.txt"
./myprog m?.txt -> Sys.argv.(1) = "m1.txt"
./myprog "m*" -> Sys.argv.(1) = "m*"
ie, wildcards are expanded before given to my program.
