How to obtain the current timestamp in Linux?

In Linux systems, you can use the date command to obtain the current timestamp.

Open the terminal and type the following command:

date +%s

After executing the command, the terminal will output the current timestamp, which is the number of seconds that have passed since January 1, 1970, 00:00:00 UTC.

Additionally, you can use the date command to convert a timestamp into a specific date and time. For example:

date -d @时间戳

Replace the timestamp above with the timestamp you want to convert, then execute the command, and the terminal will output the corresponding date and time.
