Want to check which shell am I using?

ps -p $$
echo $0

List all installed shell
cat /etc/shells

Change shell
chsh -s /bin/ksh

See my updated page "The most reliably and simple way to the current shell interpreter name on Linux or Unix-like system" https://www.cyberciti.biz/tips/how-do-i-find-out-what-shell-im-using.html

Is process running or not my Linux or Unix box?

pgrep -x nginx >/dev/null && echo "Running"
ps -C mysqld >/dev/null && echo "Yes"

See how to determine whether a process is running or not and use a conditional shell script to start/stop process https://www.cyberciti.biz/faq/bash-check-if-process-is-running-or-notonlinuxunix/ #sysadmin

Remember another day I shared my RHEL 8 beta screenshot? Someone asked me how to create KVM VM using the qcow2 image provided by Red Hat. Here is a handy little guide install the qcow2 image provided in the RHEL 8 (beta) download section. https://www.cyberciti.biz/faq/create-vm-using-the-qcow2-image-file-in-kvm/ #RHEL8 #Sysadmin
