ALL INSTALLATIONS ASSUME YES WHEN PROMPTED, that's what -y does

This script can be copy paste to ssh as is. No hands installation. :-)

yum install zsh -y
chsh -s /bin/zsh root
echo $SHELL
yum install wget git -y
wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh

/bin/cp ~/.oh-my-zsh/templates/zshrc.zsh-template ~/.zshrc
source ~/.zshrc

simple but usefull, Thanks

Unfortunatelly, CentOS is dead. But RockyLinux continues the journey of stable, free, yet enterprise Linux so perhaps this sctipt is still useful

Very good! Works fine

Collage teacher need us to learn Centos , thank u

Great! Thanks!

Btw. RockyLinux is way to go, guys. I really like it so far. Although, RedHat, mastered by evil corp IBM, tries to do everything possible to kill other variants of RHEL

To fix "zsh: command not found: chsh" on Roky , please install util-linux-user

yum install zsh -y                                                                                     
chsh -s /bin/zsh root
echo $SHELL
