Unix date tool

date is the Unix tool to check both the date and the time from the shell in Linux, Cygwin and other Unix-like systems. There is no separate tool to show the time. date is part of the GNU Coreutils package.

• By default, the tool displays the local time in your local format. On my computer, the format was like this:

$ date
Mon, Jan 21, 2019  8:42:23 AM

• To view the UTC time:

$ date -u

• To view the modification time of a file:

$ date -r foobar.txt
