compare files and beyond - UNIX for Dummies Questions & Answers

MizzGail · #1 04-23-2003

I am having a brain cramp.

I have file1 and file2.
I want to compare file1 and file2 to pull out the differences.

I am using diff and putting the results to a new file

diff file1 file2 | grep "<" > differences.out

I want to take differences.out and tag a date to the beginning of each record.

20030423 "existing record"

How do I do this?

Code:

diff file1 file2 | grep "<" > differences.out
sed "s/^/`date +%Y%m%d` /" < differences.out > TMP_00
mv TMP_00 differences.out
