Top Forums UNIX for Dummies Questions & Answers How zcat works? Post 302750155 by pamu on Monday 31st of December 2012 04:14:10 AM

Daily I works with .gz files, so I always need to use zcat.

I normally don't have a file with 40GB. I'll be having around 25-50 files of size 20-30 MB.

so I use.

Code:
zcat *.gz | #choose what i want to do.

But the important question is what you are trying to achieve with that file..?
