Add zsh to Fedora
One of my students requested an option to the bash shell. It was interesting to hear that he wanted me to instal the zsh in my Fedora image. There’s only one book that I’m aware of that’s been published on the Z Shell, and it is From Bash to Z Shell.
This post shows how to add the zsh to my Fedora image because I already release a new one for the term without the zsh shell. You use the yum utility as the root user to install the zsh library:
yum install -y zsh |
It should produce an output stream like the following, which required accessing the alternate mirror site:

Once you’ve installed the zsh, you can configure like you would the bash shell. You make edits to individual .zshrc files and generic changes to the /etc/zshrc file. You can find the documentation to edit the zsh in the User’s Guide to the Z-Shell.
The following is a modified .zshrc file. The changes enable the up-arrow in Oracle’s sqlplus and provides you with a color prompt, like this:
# Source global definitions if [ -f /etc/zshrc ]; then . /etc/zshrc fi # Uncomment the following line if you don't like systemctl's auto-paging feature: # export SYSTEMD_PAGER= # Set the JAVA_HOME path. export JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.75-2.5.4.2.fc20.x86_64 # Set the CLASSPATH path. export CLASSPATH=/usr/share/java/mysql-connector-java.jar:. # User specific aliases and functions . /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.sh # Wrap sqlplus with rlwrap to edit prior lines with the # up, down, left and right keys. sqlplus() { if [ "$RLWRAP" = "0" ]; then sqlplus "$@" else rlwrap sqlplus "$@" fi } # Set the bindkey. bindkey -v bindkey "^R" history-incremental-search-backward export EDITOR="vim" # history stuff HISTFILE=~/.zsh-histfile HISTSIZE=2000 # Set vi as a command line editor. set -o vi autoload -U colors && colors PS1="[%{$fg[red]%}%n%{$reset_color%}@%{$fg[blue]%}%m %{$fg[yellow]%}%~%{$reset_color%}% ]$ " |
The zsh prompt looks like the following:
[student@localhost ~]$
If you’re configured with a bash shell, you can change your shell to a zsh with the following command:
chsh -s /bin/zsh |
As always, I hope this helps those looking for this type of information.
