How can I get the current date and time in the terminal and set a custom command in the terminal for it?

I have to check the time in a Linux terminal.

What is the command for getting date and time in a Linux terminal?

Is there a way in which we can set a custom function?

Accepted Answer

The command is date

To customise the output there are a myriad of options available, see date --help for a list.

For example, date '+%A %W %Y %X' gives Tuesday 34 2013 08:04:22 which is the name of the day of the week, the week number, the year and the time.

You can use date to get time and date of a day:

[[email protected] ~]$date
Tue Aug 27 15:01:27 CST 2013

Also hwclock would do:

[[email protected] ~]$hwclock
Tue 27 Aug 2013 03:01:29 PM CST  -0.516080 seconds

For customized output, you can either redirect the output of date to something like awk, or write your own program to do that.

Remember to put your own executable scripts/binary into your PATH (e.g. /usr/bin) to make it invokable anywhere.
