Put screen time in your bash prompt

English

Paste this into Bash:

get_screen_time() {
since=${1:-today}
until_opt=${2:+--until "$2"}

journalctl --output json -u systemd-logind --since "$since" $until_opt | \
jq -r 'select(.MESSAGE_ID and .__REALTIME_TIMESTAMP) |
if (.MESSAGE | test("Lid opened|Starting systemd-logind|Operation .suspend. finished")) then
  .__REALTIME_TIMESTAMP + " start"
elif (.MESSAGE | test("Lid closed|Stopping systemd-logind|system will suspend")) then
  .__REALTIME_TIMESTAMP + " stop"
else
  empty
end' | \
awk -v current_time=$(date +%s%6N) '
{
    if ($2 == "start") {
        last_start = $1
    } else if ($2 == "stop" && last_start != 0) {
        total += ($1 - last_start) / 1000000
        last_start = 0
    }
}
END {
    if (last_start != 0) {
        total += (current_time - last_start) / 1000000
    }
    seconds = int(total)
    hours = int(seconds/3600)
    minutes = int((seconds%3600)/60)
    printf "%02d:%02d", hours, minutes
}'
}
PS1='$(get_screen_time) '$PS1

Now you have screen time for today in your prompt:

00:21 user@asus:~/Documents$ 
00:21 user@asus:~/Documents$ cd ../Pictures/
00:21 user@asus:~/Pictures$

Cool?

        If there is no lid (desktop pc), then it takes into account only systemd start and suspend messages, which is probably enough. Elegant!

        Accumulative duration of working sessions. Work session is a period of time limited by any of “start” events and any of “end” events. E.g between “system started” and “suspend on”, or between “lid opened” and “system turn off”. Type of events determined by regex. Effectively it’s a screen time for most of people.

      Interesting, I’d complete it with KDE Connect to add mobile usage.

        I don’t know about android, but on iPhone only way to export screen time data is to screenshot it. Probably android is also restrictive.

            You know better, I never have had an Android, but some time ago I’ve tried searching if you can get screen time data older than 2 months and came to conclusion you can’t do it on Android either. But probably it’s not an issue if you can automate export and perform it regularly.

            It would’ve been cool to have accumulative screen time across all devices. But as iOS user I don’t dream of it.

      Relies on Systemd.

      Edit: try uptime. Or, Linux only, /proc/uptime.

      Editedit: uptime is for uptime. For last login is last -n1 or “logged in since <time>” is last -s <time>.

          Only Linux distros. Which is, why i mentioned it. uptimelast works on BSD’s and not-Systemd’s too.

            Fair point, maybe in future consider adding more value to your initial comment, especially when you are referring to the usual discussion topics. Just stating that it uses systemd will make everyone think you want to start the usual pointless systemd hate nonsense discussion

        Yawn. Oh no youre using a different init than I would have preferred 🥺🥺🥺😣😭

        This is what I picture everytime someone complains about systemd.

        Systemd is great and at this point y’all just like being contrarian.

        Uptime shows how long the system has been up, not how long one has been interacting with the system.

            I don’t believe that does the same thing either. What if I lock my computer, sleep it, and step away for the day? I haven’t logged out, but my interactive session has ended.

            Last shows how long the last user logged in has been logged in. So if your system routinely has multiple users logged in, this may not be a useful metric.
