ts
ts adds a timestamp to the beginning of each line of input
The optional format parameter controls how the timestamp is formatted, as used by strftime(3) The default format is "%b %d %H:%M:%S"
ts
# no parameter default (eg. Aug 03 12:06:32) -r # relative time ago (eg. 15m5s ago) -i # incremental time since last log (eg. 00:00:00) -s # time since program start (eg "00:00:00") -m # monotonic clock (eg. Aug 03 12:06:32)
If you just want the hour/minute/second:
ts "%H:%M:%S" 12:07:45 xxxxxxxxxxxxxxxxxxx
If you just want epoch timestamp:
