Hi,all:

I've couple of large tarballs such as www.tar and images.tar. Is it possible to extract a single file or a list of files from a large tarball such as images.tar instead of extracting the entire tarball? How do I extract specific files under Linux / UNIX operating systems?

Start by doing a:

tar tvf www.tar

to get a listing of the names in the tarball.

If you need to restore a specific file or directory, do a:

tar xvf www.tar ./www/specific/folder

or

tar xvf www.tar ./www/specific.file

The files are restored relative to the current directory.

The naming "./www/specific/folder" should match the list you got from the "tar tvf" command.

The restore reads the whole archive, so it can take a while.

All versions of *Nix have man pages. These are like WinDoze help, except more technically detailed. T use them, do prompt> man <command or file>

It's possible to see what might be related by doing prompt> man -k <subject>

man tar

<snip> EXAMPLES tar -xvf foo.tar verbosely extract foo.tar

tar -xzf foo.tar.gz extract gzipped foo.tar.gz

tar -cjf foo.tar.bz2 bar/ create bzipped tar archive of the directory bar called foo.tar.bz2

tar -xjf foo.tar.bz2 -C bar/ extract bzipped foo.tar.bz2 after changing directory to bar

tar -xzf foo.tar.gz blah.txt extract the file blah.txt from foo.tar.gz <snip>
