EmployeeName=XYZ
EmployeeBand=D5
EmployeeDesignation=SSE

I need the Linux command which will read this file EmployeeDetails.txt and give the value for EmployeeBand. Output should be

Using grep: If anything is followed by EmployeeBand= will be printed. 

grep -oP 'EmployeeBand=\K.*' EmployeeDetails.txt

Using awk where = is used as field separator and second field is printed. if search criteria is meet. 

awk -F'=' '/EmployeeBand/{print $2}' EmployeeDetails.txt

Using sed ,here the band D5 is captured is a group inside () and later used using \1. 

sed -r '/EmployeeBand/ s/.*=(.*$)/\1/g' EmployeeDetails.txt
