![]() Compressing single files to store locally.Sending and receiving larger files in a compressed format.The tar GZ file extension is widely used on UNIX based operating systems but can also be used on Windows and macOS with WinZip. This format can be sent by email or social media platforms that support the Tar GZ file format. Since the tar GZ file format is used to compress and store multiple files in one, it’s most commonly used to deliver package files, programs or installers online or simply for storing files locally.īy compressing several files into one Tar GZ file, you’ll be able to send multiple files as one single archived folder. Combined into the tar GZ file extension, you can archive and compress multiple files into one. In short, a TAR file creates one archive file out of multiple files without compressing them, while the GZ file format compresses a file without creating an archive. ![]() Similarly, the TAR GZ file extension is created when compressing archived TAR files with the GNU zip utility. Short for Tape Archive, a TAR file is used to store multiple files in one to send over the internet or for archiving purposes. ![]() If os.path.splitext(tarinfo.name) = ".To understand what a Tar GZ File is, you first need to understand what a TAR file is. Python has string functions like `("foo")` Modify this check: only `yield tarinfo` if the Might really be worth the six-ish lines of Python, see the second example from the official documentation: #!/usr/bin/env python3 tar format, you'd be doing tar's job in a program / shell script of your own.Īlternatively, honestly, since a tar needs to be read sequentially anyways, and storage is usually cheap, just extract everything, noting the extracted files on the way, and delete the "wrong" ones later.Įven more alternatively, might be worth trying whether 7z extracting a tar file also aborts when a pattern doesn't match.Īnd, finally: Every proper programming language probably has a tar-consuming library. In short, aside from reading the (pretty stupid). You should then also handle the other TAR_** environment variables set to handle file/directory types, owners, modes and dates correctly. tar will set the TAR_REALNAME environment variable, which your program can use to select whether the data piped in will be written to a file of an appropriate name, or just ignored. So, that would leave you (at least in GNU tar) with the option to execute a command on each executed file, using the -to-command= option. You will not like what happens when file names contain line breaks, which is perfectly legal. If the tar archive is small enough or not read from a medium that's expensive to rewind ( actual tape archives), you could list_of_matching_files=$(tar -tf | grep '(aaa|bbb|ccc)') to compile a list of files. The GNU and BSD tar commands don't support that as far as I know, but: See for where improving the API in this regard is currently being discussed. ![]() Add the p flag to the substitutions so get a report of what substitutions are being made.īeware that with the pax implementation from MirBSD as found on Debian/Ubuntu at least, I find that if there are archive members that are symlinks, they are discarded if the symlink target doesn't match the patterns (even if their path does). To see what would be extracted, you can remove the -r. The idea being that for all archive members that contain either aaa, bbb or ccc in their path, we replace those with the same, so a no-op but that results in the next substitutions to be skipped when there's a match and in particular the s.*:: which has the effect of discarding the archive member. One option could be to use pax, the standard command to extract tar archives and use the -'s/regexp/replacement/ option to remove the members we don't want from the selection: < gunzip | ![]()
