Problema directoare c unix

[mastervlad]

Am compilat un program care imi afiseaza toate fisierele dintr-un director si ma gandeam sa-l modific astfel incat sa gasesc aceste fisiere. Vreo idee? Mersi.

PS. S-a rezolvat, m-a ajutat JIHAD, multumesc.

Cred ca ceva de genul asta vrei.

Iti listeaza fisierele din directory2 care nu exista in directory1.

#include <dirent.h>

int main(int argc, char *argv[]){
 char *temp, *temp1, *directory1, *directory2;
 DIR *dir1, *dir2;
 struct dirent *epdf;
 struct dirent *epdf2;
  if (argc == 3) {
    directory1 = argv[1];
    directory2 = argv[2];
    dir1 = opendir(directory1);
    dir2 = opendir(directory2);
    if ((dir1 != NULL) && (dir2 != NULL)){
        while (epdf = readdir(dir1)){
            temp = strdup(epdf->d_name);
                while (epdf2 = readdir(dir2)){
                    temp1 = strdup(epdf2->d_name);
                    if(strcmp(temp,temp1)!=0)
                    printf("%s/%s\n",directory2,temp1);
                }
        }
      closedir(dir1);
      closedir(dir2);
    }
  } else exit(printf("Argument missing\n"));
 printf("Done.\n");
} 

Sunt mai multe moduri in care poti face asta, eu am ales calea cea mai la indemana.

am updatat sa-ti accepte si argumente.

iti sugerez sa reverifici codul ca l-am scris in graba...

L-am verificat si am compilat, merge, dar cred ca trebuie sa precizez si calea fisierelor care apar in primul si nu apar in al2lea, cred ca trebuie o citire recursiva..

te joci tu cu el mai departe. ideea e tot asta

uite o solutie sa-ti arate cum ai zis tu.

int parsedir(char *directory1, char *directory2){
 char *temp, *temp1;
 DIR *dir1, *dir2;
 struct dirent *epdf;
 struct dirent *epdf2;
    dir1 = opendir(directory1);
    dir2 = opendir(directory2);
    if ((dir1 != NULL) && (dir2 != NULL)){
        while (epdf = readdir(dir1)){
            temp = strdup(epdf->d_name);
                while (epdf2 = readdir(dir2)){
                    temp1 = strdup(epdf2->d_name);
                    if(strcmp(temp,temp1)!=0)
                    printf("%s/%s\n",directory2,temp1);
                }
        }
      closedir(dir1);
      closedir(dir2);
    }

 free(temp);
 free(temp1);
 printf("Done.\n");
 return 0;
} 



int main(int argc, char *argv[]){

  if (argc == 3) {
  parsedir(argv[1],argv[2]);
  parsedir(argv[2],argv[1]);
  } else exit(printf("Argument missing\n"));
  return 0;
}

uite si recursiv.

iti cauta doar intr-o directie. cauta fisiere din argv[1] (recursiv, toate subfolderele) in path2(recursiv, toate subfolderele) . le afiseaza si le si numara pe cele negasite.

Sa-ti mearga in ambele directii vezi exemplul dinainte.

cu placere.

#include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>

bool *dir2compare( char *path, char *findme ){
    DIR  *dir;
    struct dirent  *entry;
    char spath[MAXPATHLEN] = "", spath2[MAXPATHLEN] = "";
    if( !(dir = opendir( path))){ perror("opendir"); exit(1);}
    for( entry = readdir( dir); entry; entry = readdir( dir)){
        sprintf( spath, "%s/%s", path, entry->d_name);
        if( entry->d_type == DT_REG){
           if(strcmp(entry->d_name,findme)==0)
              return true;
