Hello seenuvasan1985,
You can always refer man pages for options. Like as follows.
For
uptime:
Quote:
UPTIME(1) Linux User’s Manual UPTIME(1)
NAME
uptime - Tell how long the system has been running.
For
who -b:
Quote:
-b, --boot
time of last system boot
As above quotes, you can take one example
who -b tells same like when a person(OS this case) born(came up) and
uptime tells how old a person(OS this case, means what time it got rebooted last time) is. Just an silly and simple examples. Hope this helps you.
Thanks,
R. Singh
