htop doesn’t need any introduction among Linux users. It has become so much popular that I doubt anyone uses the traditional top anymore nowadays.
I wasn’t looking for any replacement or anything, but I just happened to stumble upon this fork, and what caught my eyes was the CPU temp and frequency implementation.
While it does have a precompiled deb file for armhf device, and even detailed instructions on how to install it on a Raspberry Pi, I prefer to complie things myself.

1. Dependencies
$ sudo apt install build-essential automake git libtool libncursesw5-dev
  • build-essential → dpkg-dev g++ gcc libc-dev and make.
  • automake → Required for generating files using autogen.sh.
  • git → For cloning the source code depository.
  • libtool → Library importing helper. Part of the GNU project.
  • libncursesw5-dev → An implementation of GNU ncurses. If it’s not installed, the following error message will pop up when running ./configure: error: You may want to use --disable-unicode or install libncursesw.
2. Clone the repository
$ git clone https://github.com/wbenny/htop.git

Note: It should be a good idea to cd first to a different folder other than ~/.

3. …and rest in one shot!
$ cd htop && ./autogen.sh && ./configure && make
  • cd htop → Enter the source code folder.
  • ./autogen.sh → Getting the source code from GitHub requires generating some files with this command.
  • ./configure → Configuring the compiler for this specific device. Should autodetect all CPU architectures with no problem.
  • make → The actual compiling command. It’s possible to run it in parallel by adding -j CORES (I usually use -j 2).
4. OPTIONAL: Installing it

Running make install (may require sudo) after a successful make will install htop to /usr/local/bin.
It may be a good idea to first uninstall htop is it’s installed already. (defaults to install in /usr/bin)

$ sudo apt purge htop

Note: I used purge to clear old config files as well.

5. OPTIONAL: Making sure the old config file is gone

htop creates a configuration file at ~/.config/htop/htoprc which saves the user’s preferences. It may be a good idea to remove it, to avoid compatibility issues:

$ rm ~/.config/htop/htoprc
6. Finally! Add the desired meters!
  1. htop
  2. F2 → To go to setup.
  3. Choose desired meters from the rightmost column and add them to the left or right columns.
  4. Esc → To go back.
  5. F10 → To quit and save preferences.
    Note: I usually close htop via ctrl+c, but then it skips saving preferences, so be careful there.
