runtime monitors and manages the total uptime of your system. This is achieved by adding up all individual uptimes of the system, thus resulting in a total 'runtime'.

To do this, runtime should be launched after every boot of the system in 'track' mode (see Command line Options). It will then wait until the system is shutdown, read the uptime from /proc/uptime (default), read /var/cache/runtime, add the two values together and save the result to /var/cache/runtime.

Note: runtime currently requires systemd To install runtime, you first need to compile it.

$ cd /tmp;
$ git clone https://github.com/jacksgt/runtime;
$ cd runtime;
$ make # or alternatively: $ gcc -lm main.c print.c io.c -o runtime
$ sudo cp runtime.service /etc/systemd/system/
$ sudo systemctl enable runtime # runtime will now automatically start after boot
$ sudo cp runtime /usr/local/bin

After you have set up runtime to run in the background, runtime can report the runtime and uptime of the system:

$ runtime --seconds # shows the runtime in seconds
$ runtime --uptime # shows the uptime
$ runtime # or alternatively: runtime --runtime

For more options please have a look at Command line Arguments

No worries, runtime got your back: it keeps a cache of the uptime. This means after booting the program sleeps for a while (1 hour by default), then write this value (3600 seconds) to /var/cache/runtime_cache and sleep again (and so and and so forth). This way when the computer crashes after 6 hours and 30 minutes of uptime, runtime will read the value of /var/cache/runtime_cache and at least know there were 6 hours worth of uptime. runtime will then add this value to /var/cache/runtime and move on.

Use runtime [option] where valid options are:

    --verbose (not yet functional)
    --version
    --help
    --save
    --track
    --seconds
    --uptime
    --runtime (the default option)

If you find a bug, please don't keep, but share it! I'd love to fix it. Also, if you have an suggestions or feature request, just speak up.
