ts

Add timestamps to every line from standard input. More information: https://joeyh.name/code/moreutils/.

• Add a timestamp to the beginning of each line:

{{command}} | ts

• Add timestamps with microsecond precision:

{{command}} | ts "{{%b %d %H:%M:%.S}}"

• Add [i]ncremental timestamps with microsecond precision, starting from zero:

{{command}} | ts -i "{{%H:%M:%.S}}"

• Convert existing timestamps in a text file (eg. a log file) into [r]elative format:

cat {{path/to/file}} | ts -r
