Let's fire some what I like:
ets is a command output timestamper — it prefixes each line of a command's output with a timestamp.
I love this command, let's check this:
Run a command with
$ ets ping localhost [2020-06-16 17:13:03] PING localhost (127.0.0.1): 56 data bytes [2020-06-16 17:13:03] 64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=0.036 ms [2020-06-16 17:13:04] 64 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time=0.077 ms [2020-06-16 17:13:05] 64 bytes from 127.0.0.1: icmp_seq=2 ttl=64 time=0.037 ms ...
I use for ? well I have used for adding how long take to execute a command

time mylongcommand .... long putput real 0m0.005s user 0m0.001s sys 0m0.005s
