Finger is a software tool that allows you to find information about a computer user or anyone on a network, such as their login name, full name, and when they last logged in. It provides this info by accessing a specific user profile in the system’s server, helping to know if someone is available at their terminal.
Finger Examples
#1. Using Finger for Individual Users
There are times when you might need to know if a specific person is logged into your network. Let’s consider having a colleague with the user name “Mark27”. You’re unsure if Mark27 is currently active on the network or not. To clarify this, you would use the Finger software tool.

In your command line interface, you type “Finger Mark27”. Finger then applies this command toward the user profile associated with “Mark27” on the system’s server. The tool proceeds to provide details including the full name linked to the user “Mark27”, information on where he is logged in from – his terminal, and the time he last logged in.
Therefore, by using the Finger command, you quickly and efficiently gain clarity on the online status and activity of your colleague, ‘Mark27’.
#2. Using Finger for All Users on a Network
Imagine you need a wider scope of information, say about everyone who is currently on your network, not just one person. You would still use the Finger tool, but in this case, you wouldn’t specify a particular username.
You would head to your command line interface and simply type “Finger”. Executing this command prompts Finger to go through the user profiles stored on the system server, compiling a list of everyone logged in to your network. This list will display user names, their respective full names, terminal locations, and their last login time.
By doing this, Finger allows you to gain a broad view of user activity on your network. This can be particularly valuable when assessing usage trends or diagnosing network issues.
#3. Using Finger for Users on a Remote System
Let’s now consider a scenario where you need information, not from your immediate network, but from a remote system or server. Finger has the capacity to facilitate this sort of cross-system communication as well.
In your command line interface, rather than just typing “Finger”, you would include the domain of the remote server, like this: “Finger @remoteserver.com”. The “@” symbol effectively directs the Finger command towards the specified domain.
Once executed, the Finger tool will draw up user profile information from this remote server in a similar manner to how it operates on your own network. Thus, you would then have access to a list of users, their full names, terminal locations, and last login times from the remote server.
This capacity to extend its reach makes Finger a useful tool for network administrators who have to oversee and manage multiple servers.
Conclusion
In summary, Finger is a versatile and useful software tool for gathering information on network users. Whether it’s checking on a single user, getting an overview of all users on a network, or even accessing user details from a remote server, Finger provides key insights that help foster efficient network management and communication.
