如何使用纯c或linux-shell或dos-commands创建超大文件？

#include<stdio.h>

int main() {
    FILE *fp;
    long size = 1024 * 1024 * 1024; // 1GB
    char buffer[1024];

    fp = fopen("large_file.bin", "wb");
    if (fp == NULL) {
        printf("无法打开文件\n");
        return 1;
    }

    for (int i = 0; i< size / sizeof(buffer); i++) {
        fwrite(buffer, sizeof(char), sizeof(buffer), fp);
    }

    fclose(fp);
    return 0;
}

dd if=/dev/zero of=large_file.bin bs=1G count=1
