Editor to share with you how Linux in the terminal according to your way to display the date and time, I believe that most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article, let's go to know it!

Linux's date command provides a number of options for displaying dates and times, more than you might think. These are some useful options.

On Linux systems, the date command is very simple. You type date, and the date and time will be displayed in a useful way. It includes the day of the week, date, time and time zone:

$dateTue 26 Nov 2019 11:45:11 AM EST

As long as your system is configured correctly, you will see the date and current time as well as the time zone.

However, the command also provides a number of options to display date and time information in different ways. For example, if you want to display the date for sorting, you might need to use the following command:

$date "+% Y-%m-%d" 2019-11-26

In this case, the year, month, and day are arranged in that order. Notice that we use the capital letter Y to get a four-digit year. If we use lowercase y, we will only see a two-digit year (for example, 19). Don't let this make you mistakenly think that if% m gives you a numeric month,% M may give you the name of the month. No,% M will give you minutes. To get the month in the abbreviated name format, you use% b, and for fully spelled months, use% B.

$date "+% b% B" Nov November

Or, you may want to display the date in this common format:

$date "+% D" 11-26-19

If you need a four-digit year, you can do the following:

$date "+% x" 11Universe 26Universe 2019

Here is an example that might be useful. Suppose you need to create a daily report and include a date in the file name, you can use the following command to create the file (which may be used in the script):

$touch Report- `date "+% Y-%m-%d" `

When you list your reports, they will be listed in date order or reverse date order (if you add-r).

$ls-r Report*Report-2019-11-26Report-2019-11-25Report-2019-11-22Report-2019-11-21Report-2019-11-20

You can also add other details to the date string. There are a surprising number of options available. You can use date "+% Q" to show which quarter of the year you are in, or use a command similar to the following to display the date two months ago:

$date-- date= "2 months ago" Thu 26 Sep 2019 09:02:43 AM EDT

Do you want to know the date of next Thursday? You can use commands like date-date= "next thu", but understand that for Linux, next Thursday means the Thursday after today. If today is Wednesday, it will be tomorrow, not next Thursday. However, you can specify the Thursday of next week as the second command below.

$date-date= "next thu" Thu 28 Nov 2019 12:00:00 AM EST$ date-date= "next week thu" Thu 05 Dec 2019 12:00:00 AM EST

The man page of the date command lists all its options. The list is incredible, but you may find that some date / time display options are perfect for you. Here are some things you may find interesting.

World Standard time (UTC):

$date-uTue 26 Nov 2019 01:13:59 PM UTC

Number of seconds since January 1, 1970 (related to how dates are stored on Linux systems):

$date +% s1574774137

The following is a complete list of date command options. As I said, it is much more extensive than most of us think.
