Linux pwconv Command

Linux Command Manual

The Linux pwconv command is used to enable shadow passwords for users.

In a Linux system, user and group passwords are stored in files named passwd and group, respectively. These two files are located in the /etc directory. Due to system operational requirements, anyone can read them, creating a security vulnerability. Shadow passwords move the passwords from these files into the shadow and gshadow files under the /etc directory, allowing only the system administrator to read them. Simultaneously, the original password field is replaced with the character "x", effectively enhancing system security.

Syntax

pwconv

Example

Enable shadow passwords for users:
