文本

常用示例

Revert shadow passwords

pwunconv

With specific root

pwunconv -R [/]

说明

pwunconv reverses the shadow password setup by moving password hashes from /etc/shadow back into /etc/passwd and removing the shadow file. This is the inverse of pwconv and effectively disables shadow password protection on the system. The command is part of shadow-utils and is rarely used in practice since shadow passwords are a fundamental security feature on modern Linux systems. Removing shadow protection makes password hashes readable by all users, significantly weakening system security.

参数

-R _ROOT_
Chroot directory.
