ts

Add timestamps to every line from stdin. 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
