A:
import tarfile
spam = tarfile.open( "abc.tar.gz" )
if "abc/abc1/file3.txt" in spam.getnames():
with spam.extractfile( "abc/abc1/file3.txt" ) as ham:
print ham.read()
See tarfile.

thanks for ans, but my vote goes to bash since its easy for me to pipe to look for patterns on the particular file.

Fair enough -- though you could do the same thing in python; `getnames` returns an array of files in the archive that you could search/analyse. Is there any particular reason the question is tagged `python`, btw? =p
