Simulation tree command in C
- by Ecle
I have to create the simulation of tree command in C, this is my current code:
#include <stdio.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <dirent.h>
#include <string.h>
main(int argc, char *argv[]){
int i;
if(argc < 2){
printf("\nError. Use: %s directory\n", argv[0]);
system("exit");
}
for(i=1;i<argc;i++)
//if(argv[i][0] != '-')
tree(argv[i]);
}
tree(char *ruta){
DIR *dirp;
struct dirent *dp;
static nivel = 0;
struct stat buf;
char fichero[256];
int i;
if((dirp = opendir(path)) == NULL){
perror(path);
return;
}
while((dp = readdir(dirp)) != NULL){
printf(fichero, "%s/%s", path, dp->d_name);
if((buf.st_mode & S_IFMT) == S_IFDIR){
for(i=0;i<nivel;i++)
printf("\t");
printf("%s\n", dp->d_name);
++nivel;
tree(fichero);
--nivel;
}
}
}
Apparently, it works! (due to it compiles correctly) But I don't why. I can't pass the correct arguments to execute this.
Thank you so much, people.
