[![Build status](

 https://builds.sr.ht/~sjmulder/dated)

Add a timestamp to every line of a stream:

... | **dated** [**-f** *format*]

Description

-----------

**dated** copies standard input to standard output, prepending the date and

time to every line.

The **-f** option changes the prefix format string to format, which is passed

to [strftime(3)](http://man.openbsd.org/strftime.3). The default is "%x %X ":

the local date notation, a space, the local time notation, and another space.

Note: there is no way to get subsecond precision, a limitation of

[strftime(3)](http://man.openbsd.org/strftime.3).

Examples

--------

Watch a file with [tail(1)](http://man.openbsd.org/tail.1) and see when lines

were added:

    $ tail -f test.txt | dated

    11/07/18 21:28:31 Hello

    11/07/18 21:28:40 World!

Change the output format:

    $ tail -f test.txt | dated -f "[%H:%M] "

    [21:32] Hello

    [21:33] World!
