sed multiline delete with pattern
Solution 1:
You can use the following:
sed '/{START-TAG/{:a;N;/END-TAG}/!ba};/ID: 222/d' data.txt
Breakdown:
/{START-TAG/ { # Match '{START-TAG'
:a # Create label a
N # Read next line into pattern space
/END-TAG}/! # If not matching 'END-TAG}'...
ba # Then goto a
} # End /{START-TAG/ block
/ID: 222/d # If pattern space matched 'ID: 222' then delete it.
