Date, Uptime & History

Knowing when things happen matters on a space station. The date command prints the current date and time:

date

Mon Mar 17 14:32:01 UTC 2157

The uptime command tells you how long the system has been running since its last boot:

uptime

 14:32:01 up 42 days,  3:17,  1 user,  load average: 0.12, 0.08, 0.05

This station has been online for 42 days without a reboot. Impressive stability.

Recalling past commands

The history command shows every command you have typed in the current session (and often previous ones):

history

    1  ls
    2  cd logs
    3  grep error system.log
    4  history

You can re-run a previous command by typing !NUMBER, for example !3 would re-run grep error system.log. This saves time when repeating complex commands.

Mission: Log the Timestamp

Station protocol requires a written shift log at the start of every watch: the current time, how long the station has been online, and a review of terminal activity.

1. Record the current date and time into a new file called shift-log.txt.
2. Append the station's uptime to that same file.
3. Create a folder called shift-records and move shift-log.txt into it.
4. Review the numbered list of commands you have typed this session.

Expected result

shift-records/shift-log.txt holds the timestamp followed by the station's uptime.
