+# upcheck
+
+Checker for ArchLinux available updates and send it via notify-rust.
+
+# How to install and get it working?
+
+First install [pacman-contrib](https://www.archlinux.org/packages/community/x86_64/pacman-contrib/) from ArchLinux repos:
+
+```
+# pacman -Syu --needed pacman-contrib
+```
+
+**Using AUR package:**
+
+Install the [upcheck](https://aur.archlinux.org/packages/upcheck/) package.
+
+**Manually for user only:**
+
+Installation is easy, put the `bin/upcheck` binary in $HOME/.local/bin/, then put the `upcheck.service` and `upcheck.timer` into $HOME/.config/systemd/user/. **Edit** the `upcheck.service` file in the *ExecStart=* section pointing to the `upcheck` executable path and finally enable/start `upcheck.timer` with the command `systemctl --user enable upcheck.timer && systemctl --user start upcheck.timer`
+
+**Important note**: you need a [notifications server](https://wiki.archlinux.org/index.php/Desktop_notifications#Notification_servers) if you aren't using Cinnamon, Deepin, Enlightenment, GNOME, GNOME Flashback or KDE Plasma.
+
+# Building yourself
+
+If you don't want to use the provided binary, you can compile it following the next commands:
+```
+# pacman -S rust
+$ git clone https://gitlab.com/edu4rdshl/upcheck.git
+$ cd upcheck
+$ cargo build --release
+$ cp target/release/upcheck $HOME/.local/bin/
+```
+Then continue with "How to install and get it working" skipping the binary section.
+
+# How it works?
+
+It use the `checkupdates` bash script provided by the `pacman-contrib` package. First, it exec the command `checkupdates` and save the output in a variable, if the variable is not an empty string, mean that there are available updates and then send the variable content using the  [notify-rust](https://crates.io/crates/notify-rust) crate.
+
+# What is the purpose?
+
+It doesn't have any special purpose, it was created only trying to avoid the user manual interaction of checking available updates everytime and show it when are available.
+
+# How can I change the execution frequency time?
+
+Modify the `upcheck.timer` unit and change the OnUnitActiveSec= option to what you want. See `man 7 systemd.time` for the time specifications.
+
+That is all.
