我想将目录更改为文件,我做了一些研究。在 Linux 中,inode 结构存储有关文件和目录的元数据。我想将文件保护模式从目录更改为文件,
Print some general file info
#include <time.h>
#include <stdio.h>
#include <stdlib.h>
#include <sys/stat.h>
#include <sys/types.h>
int main(int argc, char *argv[]) {
struct stat file_stats;
if(argc != 2)
fprintf(stderr, "Usage: fstat FILE...\n"), exit(EXIT_FAILURE);
if((stat(argv[1], &file_stats)) == -1) {
perror("fstat");
return 1;
}
printf("filename: %s\n", argv[1]);
printf(" device: %lld\n", file_stats.st_dev);
printf(" inode: %ld\n", file_stats.st_ino);
printf(" protection: %o\n", file_stats.st_mode);
printf(" number of hard links: %d\n", file_stats.st_nlink);
printf(" user ID of owner: %d\n", file_stats.st_uid);
printf(" group ID of owner: %d\n", file_stats.st_gid);
printf(" device type (if inode device): %lld\n",file_stats.st_rdev);
printf(" total size, in bytes: %ld\n", file_stats.st_size);
printf(" blocksize for filesystem I/O: %ld\n", file_stats.st_blksize);
printf(" number of blocks allocated: %ld\n", file_stats.st_blocks);
printf(" time of last access: %ld : %s", file_stats.st_atime, ctime(&file_stats.st_atime));
printf(" time of last modification: %ld : %s", file_stats.st_mtime, ctime(&file_stats.st_mtime));
printf(" time of last change: %ld : %s", file_stats.st_ctime, ctime(&file_stats.st_ctime));
return 0;
}
有没有办法将目录更改为文件?如何通过C程序修改inode结构?
