Crest, A Top-Like Task Manager Has Been Released For Jolla’s Sailfish OS

Hello Sailfish OS Enthusiasts. Crest is a Unix top-like application (some kind of task manager), that displays the processes on the phone, sorted by CPU or memory usage, enabling the user to kill the processes he wants.

Also worth mentioning: the Memory column displaying the Resident Set Size (RSS) shows a bigger number for the memory usage, since it includes the shared resources. Also, the Average load includes the processes waiting for IO, so it does not display the CPU utilization exactly.

The latest version available is Crest 1.0.1, which has been recently released. In this article I will show you how to install Crest 1.0.1 on Jolla’s Sailfish OS.

There are two installation methods, one from the GUI and one from the command line interface. I like the terminal method better, because I find it easier to update the apps, this was. And because I am a CLI Linux maniac. : )

Installation method 1: From the GUI.

Since Crest is available via, you can easily download the app and install it directly from the file manager.

Installation method 2: In the geek way, via zypper.

Since Sailfish OS is pure openSUSE, you have to switch to developer mode, install zypper, add the repository and key, update the system and install Crest app. Like this:

# pkcon install zypper
# zypper ar -f
# rpm --import
# zypper refresh
# zypper install harbour-crest

To uninstall Crest, you have to install zypper (if you haven’t installed it already) and uninstall the app via zypper :

# pkcon install zypper
# zypper remove harbour-crest

For those who don’t know yet, Jolla is a project developed by former Nokia employees. The first Jolla smartphone is running on Sailfish OS, a modified Megoo Linux system, which is Android compatible, uses Wayland as the default display server , uses Nokia N9′s Maliit touchscreen keyboard and comes with interchangeable covers, allowing the users to easily switch them, in order to change the color/model of the phone and comes with impressive hardware specifications.

While apps with native Sailfish OS support can be installed via the Jolla Store and, Android apps can be installed via the same Jolla Store, or via F-Droid, Yandex Store, Amazon App Store, Aptoide and 1Mobile Android Market.
