Explore advanced features: Through study and practice, you can harness the power of C to create complex and customizable scripts and tools that will improve your productivity and quality of life.

Use C scripts and tools to automate your life

C language, with its efficient and flexible features, makes it a Ideal for automation scripts and tools. For beginners, mastering the C language allows you to easily create powerful programs that simplify daily tasks and increase productivity.

1. Create a simple script

#include <stdio.h>

int main() {
    printf("Hello, world!\n");
    return 0;
}

Compiling and running this script will output "Hello, world!" to the console.

2. Utility tools

File manager:

#include <stdio.h>
#include <stdlib.h>

int main() {
    system("ls -la");  // 列出当前目录的文件和目录
    return 0;
}

File operation:

#include <stdio.h>
#include <stdlib.h>

int main() {
    FILE *fp;
    char c;

    fp = fopen("test.txt", "r");  // 打开文件
    if (fp == NULL) {
        perror("Error opening file");
        exit(EXIT_FAILURE);
    }

    while ((c = fgetc(fp)) != EOF) {  // 逐个字符读取文件
        printf("%c", c);
    }

    fclose(fp);  // 关闭文件
    return 0;
}

Process Management:

#include <stdio.h>
#include <stdlib.h>

int main() {
    int status;
    pid_t pid;

    pid = fork();  // 创建子进程
    if (pid < 0) {
        perror("Error creating child process");
        exit(EXIT_FAILURE);
    } else if (pid == 0) {  // 子进程
        execlp("ls", "-la", NULL);  // 执行 "ls -la" 命令
    } else {  // 父进程
        wait(&status);  // 等待子进程完成
    }

    return 0;
}

Through study and practice, you can leverage the power of the C language to create more complex and customizable scripts and tools , thereby realizing various automated tasks and improving your work efficiency and quality of life.
