tstdin

Timestamp your pipeline.

$ (echo foo ; sleep 1; echo bar ; sleep 1 ; echo baz) | tstdin
2031-04-07 14:20:03.952221 00:00:00.000003 00:00:00.000003 foo
2031-04-07 14:20:04.952120 00:00:00.999902 00:00:00.999898 bar
2031-04-07 14:20:05.953362 00:00:02.001144 00:00:01.001241 baz

For each line received on STDIN, it outputs:

• (1) the current date/time including microseconds
• (2) hours, minutes, seconds and microseconds since the start
• (3) hours, minutes, seconds and microseconds since the last line was received
• (4) the line that was received

… all separated by spaces.

If the time between the previous line and the current one took too long, the (3) token will be output with color: red if it took more than a minute, or yellow if it took more than a second.

Colors are automatically disabled if STDOUT is not a terminal, if TERM=dumb or if either NO_COLOR or TSTDIN_NO_COLOR are set in the environment, but see the -color and -no-color options.
