gostamp

Timestamp and colorize the stdout and stderr streams of CLI programs.

(based on an idea by HN user chrismorgan here: https://news.ycombinator.com/item?id=18898764)

Examples:

This example shows a default invokation of 'gostamp', running 'make', which produces both stdout and stderr lines:

As you can see, it is easy to distinguish between stderr (red timestamps) and stdout (green timestamps).

The example below shows the effect of the -absolute option:

Installation:

go install github.com/spytheman/gostamp@latest

Usage:

gostamp - Timestamp and colorize the stdout and stderr streams of CLI programs.
Usage: gostamp [options] program [programoptions] 
  The options are:
  -absolute
        use absolute timestamps
  -color
        colorize the output (default true)
  -csv
        do not format the output at all, just show the time in ns, followed by ',' then the output
  -elapsed
        use timestamps, showing the elapsed time from the start of the program. Can not be used with -absolute
  -end
        timestamp the end of the execution (default true)
  -merge
        merge stderr to stdout. Useful for later filtering with grep.
  -micro
        round timestamps to microseconds, instead of milliseconds. Can not be used with -absolute
  -nobuf
        run the program with stdbuf -i0 -oL -eL, i.e. with *buffering off* for the std streams
  -start
        timestamp the start of the execution (default true)
  -version
        show the tool version
