Node.js | fs.chownSync()方法
原文:https://www.geeksforgeeks.org/node-js-fs-chownsync-method/
fs.chownSync()方法用于同步更改给定路径的所有者和组。该功能接受用户 id 和组 id，可用于设置各自的所有者和组。它不返回任何东西。
语法:
fs.chownSync( path, uid, gid )
参数:该方法接受三个参数，如上所述，如下所述:
- Path: It is a string, buffer or web address that indicates the path of the file that the owner and group must change.
- uid: is a number representing the user id corresponding to the owner to be set.
- Gid: is a number representing the group ID corresponding to the group to be set.
下面的例子说明了 Node.js 中的 fs.chownSync()方法:
示例 1: 本示例显示了所有者的设置。
// Node.js program to demonstrate the
// fs.chownSync() method
// Import the filesystem module
const fs = require('fs');
let filepath = "example_file.txt";
// Set the owner to a new one keeping the group same
// New owner is "geeksforgeeks" with user id 1100
// The old group is "xubuntu" with group id 999
fs.chownSync(filepath, 1100, 999);
console.log("Given uid and gid set successfully");
运行代码前:
xubuntu@xubuntu: ~/Desktop/fs-chownSync$ ls -l
total 8
-rw-rw--w- 1 xubuntu xubuntu 4 Apr 23 09:08 example_file.txt
-rw-rw-r-- 1 xubuntu xubuntu 290 Apr 23 09:08 index.js
代码输出:
Given uid and gid set successfully
运行代码后:
xubuntu@xubuntu: ~/Desktop/fs-chownSync$ ls -l
total 8
-rw-rw--w- 1 geeksforgeeks xubuntu 4 Apr 23 09:08 example_file.txt
-rw-rw-r-- 1 xubuntu xubuntu 290 Apr 23 09:08 index.js
示例 2: 此示例显示了组的设置。
// Node.js program to demonstrate the
// fs.chownSync() method
// Import the filesystem module
const fs = require('fs');
let filepath = "example_file.txt";
// Set the group to a new one keeping the owner same
// New group is "editor" with group id 1201
fs.chownSync(filepath, 999, 1201);
console.log("Given uid and gid set successfully");
运行代码前:
xubuntu@xubuntu: ~/Desktop/fs-chownSync$ ls -l
total 8
-rw-rw--w- 1 xubuntu xubuntu 4 Apr 23 09:08 example_file.txt
-rw-rw-r-- 1 xubuntu xubuntu 290 Apr 23 09:08 index.js
代码输出:
Given uid and gid set successfully
运行代码后:
xubuntu@xubuntu: ~/Desktop/fs-chownSync$ ls -l
total 8
-rw-rw--w- 1 xubuntu editor 4 Apr 23 09:08 example_file.txt
-rw-rw-r-- 1 xubuntu xubuntu 290 Apr 23 09:08 index.js
