This article mainly explains "how to get yesterday or tomorrow time through date command in linux". The explanation in the article is simple and clear and easy to learn and understand. Please follow the editor's train of thought to study and learn "how to get yesterday or tomorrow time through date command in linux".

For example:

The code is as follows:

Date + "% F"

Output format: 2011-12-31

Date + "F H:%M:%S"

Output format: 2011-12-31 16:29:50

This is to print out the current time of the system, and if you want to get a certain time relative to the current time, what you need to do, you can do it through the-d parameter. For example:

The code is as follows:

Date-d "tomorrow" + "F H:%M:%S"

Output the time at this time tomorrow

Date-d "yesterday" + "F H:%M:%S"

Output the time at this time yesterday

If I want to get the time 13 days ago, the-d parameter has a more flexible use, such as:

The code is as follows:

Date-d "- 1 day ago" + "F H:%M:%S"

Output the time at this time tomorrow

Date-d "1 day ago" + "F H:%M:%S"

Output the time at this time yesterday

Date-d "1 week ago" + "F H:%M:%S"

Output the time at this time seven days ago, which is equivalent to

Date-d "7 day ago" + "F H:%M:%S"

You can see the power of ago. The first number can be negative, the negative number represents the future time, the positive number represents the past time, and the second parameter minute, hour, day, month, week.
