Linux hand command

The hand control in Linux is generally a customer details search system. Following is its syntax:

finger [-lmsp] [user ...] [[email protected] ...]

And here’s how the tool’s man website describes it:

The hand shows details about this method customers.

Following are some Q&A designed illustrations that should provide you with a better concept on how the hand control performs.

Q1. How to use hand command?

Basic utilization is easy, just perform ‘finger’ with name of a customer as feedback. Here’s an example:

finger himanshu

And here’s the outcome the above control created on my system:

Login: himanshu                   Name: Himanshu
Directory: /home/himanshu Shell: /bin/bash
On since Sat Nov 24 10:16 (IST) on :0 from :0 (messages off)
No email.
No Strategy.

Q2. How to create hand show outcome material wise?

This can be done using the -s control range choice. Here’s an example:

finger -s himanshu

And here’s the outcome produced:

Login     Name       Tty      Nonproductive  Sign in Time   Workplace     Workplace Phone
himanshu Himanshu *:0 Nov 24 10:16 (:0)

Q3. How to create hand limit some details in output?

There’s an order range choice -p that causes hand to not show the items in the “.plan”, “.project” and “.pgpkey” data files. Here’s an example:

finger -p himanshu

And here’s the output:

Login: himanshu                   Name: Himanshu
Directory: /home/himanshu Shell: /bin/bash
On since Sat Nov 24 10:16 (IST) on :0 from :0 (messages off)
No email.

So you can see details associated with ‘plan’ was not shown in the outcome.

Q4. How to avoid relevant of customer actual names?

By conventional, the feedback username you offer is printed for customer login titles as well just as actual titles. But if you want, you can turn off the latter relevant using the -m control range choice.

finger -m himanshu

Q5. What are some other factors worthwhile to understand finger?

Here’s a appropriate clip from the tool’s man page:

If no choices specified, hand non-payments to the -l design outcome if operands are offered, 
otherwise to the -s design. Observe that some areas may be losing, in either structure, if details
is not available for them.

If no justifications are specified, hand will create an access for each customer currently signed into the
system.

Finger may be used to look up customers on a distant device. The structure is to specify a customer as
[email protected]”, or “@host”, where the conventional outcome structure for the former is the -l design, and the
default outcome structure for the latter is the -s design. The -l choices your best choice that may
be approved to a distant device.

If conventional outcome is a outlet, hand will release a buggy come back (^M) before every linefeed (^J).
This is for handling distant hand demands when invoked by fingerd(8).
