lchfn - Change finger information

lchfn \[*OPTION*\]... \[*user*\]

## DESCRIPTION

Displays and allows changing information about *user*  that is available using the [**finger**(1)](/finger/1.md) command (usually stored in the "gecos" field of */etc/passwd*).

If the *user* argument is not provided, username of the invoking user is used; the *user* argument is ignored if **lchfn** is run set-uid to a different user.

Entering an empty string (by pressing Enter) at a prompt is interpreted as accepting a default value; to erase an attribute (or to use an empty string as the attribute value), enter a single dot character.
