1) sed -n '1,3'p test.sh ------> prints 1 to 3 lines
2) awk '{print}' test.sh -------> prints the whole file
3) awk ’/Manager/{print}’ test.sh prints lines with "manager" word
4) awk -F'[.]' '/^version/{print $1"."$2"."$3"."$4+1}’ test.sh
version=20.1.2.3 -- Version Incerement
5) sed -i ‘s/tenth/eleven/g’ test.sh -> Replace a value in a file
6) myVar=`echo $hello | sed 's/=/ /g' | awk '{print $2}'`
AUTOMATION 1 - IF ELSE BLOCK WITH JFROG REST API
CICD=true
