How to Change User Data With chfn and usermod on Linux
If you use a Linux or Unix-like computer, you’ll have a user account. The name given to the account is your user account name. This is the name you use to log in with. It’s also (by default) the name of your login group and the name of your home directory. They all use the same identifier.
There is another set of information that can be stored for each user account. Real-world data such as the person’s full name, their office number, and their work telephone number, for example, can be defined and attached to them. Indeed, completely arbitrary snippets of information can be tagged to user accounts.
In practical terms, this will be more useful for system administrators looking after computers that have many user accounts configured on them. But even for the single-user Linux computer, it’s always interesting to know what’s going on beneath the hood.
