fnmatch() function for wildcards

Francinoman · 10-26-2006, 07:23 PM

Hi there!

I am creating a new shell in C, and I am trying to implement the ability of wildcards. So for example if the user was to type : ls *.c

a list of all the .c files in a directory would be displayed.

I have done a bit of research and found that the function fnmatch() will help me do this. however i was wondering if anyone could help me do this? Or if anyone knows of a good example using fnmatch() so I can get a better idea of how the function works...

Thanks guys!

These forums have got me soooooo far in my shell program.

Shells normally use globbing. The glob function is easy to call.
Consider:

Code:

#include <stdlib.h>
#include <glob.h>

int main(int argc, char *argv[])
{
    glob_t globbuf;
    int i=0;

    if(glob (argv[1], 0, NULL, &globbuf)==GLOB_NOMATCH)
        return 1;
    while(i<globbuf.gl_pathc)
    {
        printf("%s\n", globbuf.gl_pathv[i++]);
    }
    globfree(&globbuf);
    return 0;
}
