Is it possible to read a text file line by line from an archive?

Question

*nix-like systems

Hi everybody!
There are multi-gigabyte archives with text files.
I wonder if it is possible to read the text line by line without unpacking to save disk space.
An example in perl is welcome, but it is also possible in other languages, if possible, of course)

UPD: The question is really lamer. There is a specially trained zcat command for gzip archives.
zcat ./test.txt.gz | perl ./fork.pl
Thanks everyone for the replies!

Answer 1

Search Google for "tar extract one file grep".
Here we find:

An example of a finished command:
tar xzf Archive.tar.gz File.txt -O | grep Privet

Answer 2

Depends on the archive format. If it's just a single text file packed with bzip or gzip, you can use a pipeline:
As a result, all lines from the file will come to the program on standard input.

Answer 3

It seems to me that the comrade means whether it is possible to unpack archives line by line according to the content of the text. The answer is simply no. However, it is possible to split large archives into smaller ones and process them in the manner indicated in previous answers.
