You don't need to store the entire decompressed file on disk.
Or on some systems, just
As far as I know you can't extract all files beginning with a certain string though.
It has to scan the whole file to find the ones you want.
True, but you can make one pass to get the names of the files in the tar archive and save the names of the files you want using grep (or some other tool) and then extract the files you want on a second pass. The 1st pass would be something like:
Again, this does not save the entire uncompressed archive to disk. And, of course, if you try this and find that it gives you the list of files you want, you could try:
as long as the list of filenames to be processed doesn't cause that command line to overflow your system's ARG_MAX limit.

TAR(1) General Commands Manual TAR(1)NAME
tar - archiver
SYNOPSIS
tar key [ file ... ]
DESCRIPTION
Tar saves and restores file trees. It is most often used to transport a tree of files from one system to another. The key is a string
that contains at most one function letter plus optional modifiers. Other arguments to the command are names of files or directories to be
dumped or restored. A directory name implies all the contained files and subdirectories (recursively).
The function is one of the following letters:
c Create a new archive with the given files as contents.
x Extract the named files from the archive. If a file is a directory, the directory is extracted recursively. Modes are restored if
possible. If no file argument is given, extract the entire archive. If the archive contains multiple entries for a file, the lat-
est one wins.
t List all occurrences of each file in the archive, or of all files if there are no file arguments.
r The named files are appended to the archive.
The modifiers are:
v (verbose) Print the name of each file treated preceded by the function letter. With t, give more details about the archive entries.
f Use the next argument as the name of the archive instead of the default standard input (for keys x and t) or standard output (for
keys c and r).
u Use the next (numeric) argument as the user id for files in the output archive. This is only useful when moving files to a non-Plan
9 system.
g Use the next (numeric) argument as the group id for files in the output archive.
EXAMPLES
Tar can be used to copy hierarchies thus:
{cd fromdir; tar c .} | {cd todir; tar x}

There is no way to ask for any but the last occurrence of a file.
File path names are limited to 100 characters.
The tar format allows specification of links and symbolic links, concepts foreign to Plan 9: they are ignored.
