[command] | gnomon

[command] | gnomon --type=elapsed-total
Show absolute timestamps
[command] | gnomon --type=absolute
Highlight lines
[command] | gnomon --high=1.5
Set both high and medium
[command] | gnomon --high=3.0 --medium=1.0
Ignore lines
[command] | gnomon --ignore-blank --high=0.5
说明
gnomon is a command-line utility that prepends timestamp information to the output of another command, piped through stdin. By default, it shows how long each line of output took to appear, making it useful for identifying slow steps in build processes, test suites, or log output. The tool color-codes output based on configurable time thresholds: lines exceeding the --high threshold are shown in red, those exceeding --medium in yellow, and the rest in the default color.
参数
- --type _TYPE_
- Timestamp type: elapsed-line (default), elapsed-total, or absolute.

- --high _SECONDS_
- Threshold in seconds for high (red) time coloring. Default: 1.0.
- --medium _SECONDS_
- Threshold in seconds for medium (yellow) time coloring. Default: 0.5.
- --help
