我写这个代码，如果从与要删除的文件相同的目录中调用，它不会取消链接文件，它将从其他dir文件中取消链接
.section .data fpath: .asciz "/home/user/filename" # path to file to delete .section .text .globl _start _start: movl $10, %eax # unlink syscall movl $fpath, %ebx # path to file to delete int $0x80 movl %eax, %ebx # put syscall ret value in ebx movl $1, %eax # exit syscall int $0x80 我想要的是取消它所在的目录中的所有文件（包括它自己）的链接。
您需要递归删除目录内容，然后才能删除目录本身。 以下是在C中，但不使用标准库函数，只有系统调用：
#define _LARGEFILE64_SOURCE #define _FILE_OFFSET_BITS 64 #include <dirent.h> #include <fcntl.h> #include <sys/syscall.h> #include <sys/types.h> #include <unistd.h> struct linux_dirent64 { ino64_t d_ino; off64_t d_off; unsigned short d_reclen; unsigned char d_type; char d_name[]; }; static void rmrf(int dfd, const char *name) { unsigned char buffer[16384]; struct linux_dirent64 *dirent; int fd, off, size; fd = syscall(SYS_openat, dfd, name, O_RDONLY | O_DIRECTORY); if (fd == -1) { syscall(SYS_exit, 1); } do { size = syscall(SYS_getdents64, fd, buffer, sizeof(buffer)); if (size < 0) { syscall(SYS_exit, 1); } for (off = 0; off < size; off += dirent->d_reclen) { dirent = (struct linux_dirent64 *)&buffer[off]; if (dirent->d_name[0] == '.' && (dirent->d_name[1] == '\0' || (dirent->d_name[1] == '.' && (dirent->d_name[2] == '\0')))) { continue; } if (dirent->d_type != DT_DIR) { if (!syscall(SYS_unlinkat, fd, dirent->d_name, 0)) { continue; } if (dirent->d_type != DT_UNKNOWN) { syscall(SYS_exit, 1); } } rmrf(fd, dirent->d_name); } } while (off); syscall(SYS_close, fd); if (syscall(SYS_unlinkat, dfd, name, AT_REMOVEDIR)) { syscall(SYS_exit, -1); } } int main() { const char fpath[] = "/home/user/filename"; if (syscall(SYS_unlink, fpath)) { rmrf(0, fpath); } syscall(SYS_exit, 0); }
