I would say it’s possible, by playing with TarInfo e TarFile.addfile passing a StringIO as a fileobject. Very rough, but works import tarfile import StringIO tar = tarfile.TarFile(“test.tar”,”w”) string = StringIO.StringIO() string.write(“hello”) string.seek(0) info = tarfile.TarInfo(name=”foo”) info.size=len(string.buf) tar.addfile(tarinfo=info, fileobj=string) tar.close()
I also encounter the tar messages “changed as we read it”. For me these message occurred when I was making tar file of Linux file system in bitbake build environment. This error was sporadic. For me this was not due to creating tar file from the same directory. I am assuming there is actually some … Read more
Use this: find . -type f -print0 | tar -czvf backup.tar.gz –null -T – It will: deal with files with spaces, newlines, leading dashes, and other funniness handle an unlimited number of files won’t repeatedly overwrite your backup.tar.gz like using tar -c with xargs will do when you have a large number of files Also … Read more
What about just getting a listing of the tarball and throw away the output, rather than decompressing the file? tar -tzf my_tar.tar.gz >/dev/null Edited as per comment. Thanks zrajm! Edit as per comment. Thanks Frozen Flame! This test in no way implies integrity of the data. Because it was designed as a tape archival utility … Read more
tar -cjf site1.tar.bz2 -C /var/www/site1 . In the above example, tar will change to directory /var/www/site1 before doing its thing because the option -C /var/www/site1 was given. From man tar: OTHER OPTIONS -C, –directory DIR change to directory DIR
You can do this with the PharData class: // Example: list files $archive = new PharData(‘/some/file.tar.gz’); foreach($archive as $file) { echo “$file\n”; } This even works with the phar:// stream wrapper: $list = scandir(‘phar:///some/file.tar.gz’); $fd = fopen(‘phar:///some/file.tar.gz/some/file/in/the/archive’, ‘r’); $contents = file_get_contents(‘phar:///some/file.tar.gz/some/file/in/the/archive’); If you don’t have Phar, check the PHP-only implementation, or the pecl extension.
you can use getmembers() >>> import tarfile >>> tar = tarfile.open(“test.tar”) >>> tar.getmembers() After that, you can use extractfile() to extract the members as file object. Just an example import tarfile,os import sys os.chdir(“/tmp/foo”) tar = tarfile.open(“test.tar”) for member in tar.getmembers(): f=tar.extractfile(member) content=f.read() print “%s has %d newlines” %(member, content.count(“\n”)) print “%s has %d spaces” … Read more
You can have multiple exclude options for tar so $ tar –exclude=”./folder” –exclude=”./upload/folder2″ -zcvf /backup/filename.tgz . etc will work. Make sure to put –exclude before the source and destination items.
You can do this with the Apache Commons Compress library. You can download the 1.2 version from http://mvnrepository.com/artifact/org.apache.commons/commons-compress/1.2. Here are two methods: one that unzips a file and another one that untars it. So, for a file <fileName>tar.gz, you need to first unzip it and after that untar it. Please note that the tar archive … Read more
