Hi, The task was to delete lines with the word copyright irrespective of case.
I used the command - sed ‘/copyright/Id’ /home/BSD.txt > /home/BSD_DELETE.txt
and validate the output file using grep -i command - cat /home/BSD_DELETE.txt | grep -i copyright
still the task failed 
screenshot attached.
Hi @sneha1
As per the task description you need to take care about the case sensitivity, so that you only delete the string mentioned but Id will delete all matching strings irrespective of their case.
