To check the current date and time in Bash, you can use the date command. By simply running the date command in your Bash terminal, it will display the current date and time according to your system's settings.
Here's an example of how you can use the date command to display the current date and time:
1
|
$ date
|
This command will output something similar to the following:
1
|
Mon Oct 18 09:47:25 UTC 2021
|
The displayed information includes the day of the week, the month, the day of the month, the time in HH:MM:SS format, the time zone (in this case, UTC), and the year.
You can also format the output of the date command to display the current date and time in a specific format. For example, if you want to display only the date in the format of "YYYY-MM-DD", you can use the following command:
1
|
$ date +%Y-%m-%d
|
This will output the current date in the desired format, such as:
1
|
2021-10-18
|
Similarly, you can format the output to display the time or a specific combination of date and time elements as per your requirements.
That's how you can check the current date and time in Bash using the date command.
