Bash force script execution by a user

Inspired by the oneStack script:

It turns out that the script can be executed with a certain user permission easily.

The script content is as follows:

#! /Bin/bash # filename: test. sh # email: wangxiaoyu@Live.com # date: 2013-09-02user = "root" if ['whoam '! = "$ {User}"]; then exec su-"$ {user}"-c "sh $ {PWD}/test. sh "fiecho" The following is the script body content "idecho" the end of executing the id command"

The debugging information is as follows:

Xiaoyuwang @ localhost :~ $ Sh-x test. sh

+ User = root

+ Whoami

+ [Xiaoyuwang! = Root]

+ Exec su-root-c sh/home/xiaoyuwang/test. sh

Password:

The content of the script body is as follows:

Uid = 0 (root) gid = 0 (root) groups = 0 (root)

The execution of the id command ends.
