I find your description confusing. It seems like you are saying you have two files (for example file1 and file2) and if the two files do not have the same contents, you want to replace the contents of the 1st file with the contents of the 2nd file. The simple way to do that is to forget about comparing them and just copy the contents of the 2nd file to the 1st file:

Code:

cp file2 file1

Hello Don

My requirement is not to distrub secondary content of the file1 , I just want to replace only primary content.


Thank you

This seems to work with your sample input:

Code:

ed -s file1 <<EOF
	/[*].*Primary.*[*]/,/[*].*End.*Primary.*[*]/d
	0r file2
	w
	q
EOF

Thank you Don.. it works
