End of record markers - UNIX for Dummies Questions & Answers

Dave Miller · #1 10-07-2008

I have a file with thousands of 80 character records.

Unfortunately, there are no end of record characters, so any normal script commands that I've tried will process the entire file as one record.

I.E. If I use grep to find the record that contains some specific value, I either get nothing if it's not found, or the entire file, regardless of how many times the string exists. Obviously, I only want the 80 character records that have the string I'm looking for.

How can I convert the file to be true 80 character records so I can use normal script commands?

Thanks

try this:

Code:

sed 's/\(.\{80\}\)/\1\n/g' your.log > yournew.log

Or just fold -w 80 file

fold

Yeah, that's the ticket. I just knew there'd be a simple way to do this.

And, bonus... I can leave out the -w 80 since that's the default!

Thanks.
