Install ZSH#

  • Zsh (short for Z Shell) is a feature-rich and powerful shell program for Unix-like operating systems with lots of interactive features. It is an extended version of the Bourne Shell (sh), with a large number of new features, and support for plugins and themes. It is designed for interactive use and it is also a powerful scripting language.
1
sudo dnf install zsh
  • Check zsh installed version
1
zsh --version
  • Configure zsh
1
zsh

  • Then you will see the instruction for the first configuration.

    • Press 1 to go to the main menu and configure each setting individually.
    • Press 2 to populate the .zshrc configuration file with the default parameters, which you can later change manually in the .zshrc file.
    • Press 0 to create an empty .zshrc configuration file and configure everything from scratch.
    • Press q to exit the configuration and start it again the next time you enter Zsh.

  • Then let's set the zsh as default shell.

  • Firstly, let's check the default shell
1
echo $SHELL
  • If the default shell is /bin/bash then we can change it to zsh by running the command below.
1
chsh -s $(which zsh)
  • After that, let's reload the zsh by command.
1
source ~/.zshrc

Install Oh-My-Zsh in Fedora#

  • Install oh-my-zsh in fedora
1
sh -c "$(wget https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh -O -)"
  • Config theme for oh-my-zsh.
1
gedit $HOME/.zshrc
  • If you check, robbyrussel is the default theme for ZSH.
.zshrc

...
# Set name of the theme to load --- if set to "random", it will
# load a random theme each time oh-my-zsh is loaded, in which case,
# to know which specific one was loaded, run: echo $RANDOM_THEME
# See https://github.com/ohmyzsh/ohmyzsh/wiki/Themes
ZSH_THEME="robbyrussell"
...

  • Therefore, to replace or change your ZSH theme, get the name of the theme from $HOME/.oh-my-zsh/themes/ folder and substitute the robbyrussell with the new name of your preferred theme.

  • For example, to change the themes to fino-time theme, $HOME/.oh-my-zsh/themes/fino-time.zsh-theme

.zshrc

# See https://github.com/ohmyzsh/ohmyzsh/wiki/Themes
ZSH_THEME="fino-time"
...
  • Then save and run command below to reload.

Make Second Hard Disk As Fedora Installer#

  • This session will be useful if you using Windows and you want to install the Fedora but you don't have the USB stick and you only have 2 Disks: one disk is used for Windows and the other Disk is free. If you have the USB stick then just go with it as documented in the fedora documentation
  • Firstly on the Windows machine you should create a WSL2 machine. You can follow steps in WSL2 or the Microsoft Documentation.
  • Then for the Free Disk that don't have the installed Windows. Let's open the Disk Management of Windows and delete the volume of that Disk.

#zoom

  • Now, let's mount the hard disk into the WSL2 machine.

  • Let's open the Windows Power Shell with the Administration and use the command below to list all the available disks with the DeviceID

1
 GET-CimInstance -query "SELECT * from Win32_DiskDrive"
  • Then you can see the results as below.

\\.\PHYSICALDRIVE2 KINGSTON SNV2S500G   3          500105249280  KINGSTON SNV2S500G
  • Now, you can detect disk that you want to mount and use the command below with the DeviceID.
1
wsl --mount \\.\PHYSICALDRIVE2
  • Then let's run the command below to identify the desk that you want to format as FAT32.
1
lsblk -f

  • This command lists all block devices and their current filesystem information. Locate the partition you intend to format (e.g., /dev/sdb1).

  • Then run the command below to format the disk to FAT32

1
sudo mkfs.vfat /dev/sdb1
  • Now, in the WSL2 machine let's download the Fedora Distro that you want. For example we will download the Fedora Silverblue 42 ISO file by using the command below.
1
wget https://download.fedoraproject.org/pub/fedora/linux/releases/42/Silverblue/x86_64/iso/Fedora-Silverblue-ostree-x86_64-42-1.1.iso
  • Then run the command below to create the Fedora boot disk.
1
dd if=/path/to/Fedora-Live-Security-x86_64-21.iso of=/dev/sdb1
  • For example.
1
dd if=Fedora-Silverblue-ostree-x86_64-42-1.1.iso of=/dev/sdb1
  • After all, let's reboot and in the boot option, let's choose the disk that you install Fedora installation and now you can do the Fedora installation and you can install on the disk that you installed Windows.

Use Podman Of Host Machine From ToolBox In Fedora Silverblue#

  • If you are using the Fedora Silverblue then you can see that, by default the Podman is installed in the host machine and if you are using toolbox which is actually a podman container and there is no podman installation there. So to use the installed Podman in the host machine from the toolbox then you use the command below.
1
flatpak-spawn --host <command>
  • For example
1
flatpak-spawn --host podman ps
  • Then you can see the result.

  • Now, let's create alias for the command above then you don't have to type a long command every time you want to use podman from the host machine.
  • Let's open the ~/.zshrc and add the command below to the end of that file.
1
2
alias podman="flatpak-spawn --host podman"
alias podman-compose="flatpak-spawn --host podman-compose"
  • Then reload the ~/.zshrc by using the command source ~/.zshrc.
