ts

Add timestamps to every line from standard input.

• Add a timestamp to the beginning of each line:

{some_command} | ts

• Add timestamps with microsecond precision:

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

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

{some_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
