`interval` is in seconds, but you can specify a unit. Units are the following:

`m` for minutes; `h` for hours; and `d` for days. There could be as many `interval`s passed as you need.

First run `make` to build a program, and then `make install` to copy executable in `/usr/bin/`. Later, use `make uninstall` to delete it, or just delete `/usr/bin/kwh-cost`.

### For ArchLinux
|
||||
|
||||
You can take a [PKGBUILD](/Arav/kwh-cost/raw/branch/master/PKGBUILD) file and in a directory with it run `makepkg -i`.
|
||||
|
||||
If you want to use a pre-built package for Arch from Releases, then install it using `pacman -U` command.
