Is it possible to do it using tarfile ? Or is there any suggestions? 回答1: You can obtain each file from a tar file as a python file object using the .extractfile() method. Loop over the tarfile.TarFile() instance to list all entries: import tarfile with tarfile.open(path) as tf: for entry in tf: # list each entry one by one fileobj = tf.extractfile(entry) # fileobj is now an open

This is my example code. writeLines('aaaa', 'tmp.txt') tar('tmp.tar.gz', 'tmp.txt', compression = 'gzip') This code creates a tmp.tar.gz, but tmp.txt doesn't include in the gz file.

问题 I have a large tar file I split . Is it possible to cat and untar the file using pipeline. Something like: cat largefile.tgz.aa largefile.tgz.ab | tar -xz instead of: cat largefile.tgz.aa largfile.tgz.ab > largefile.tgz tar -xzf largefile.tgz I have been looking around and I can't find the answer. I wanted to see if it was possible. 回答1: Use - as the input file: cat largefile.tgz.aa largefile.tgz.ab | tar zxf - Make sure you cat them in the same order they were split. If you're using zsh you

Deleting files after adding to tar archive

由 末鹿安然 提交于 2019-12-03 06:29:22
问题 Can GNU tar add many files to an archive, deleting each one as it is added? This is useful when there is not enough disk space to hold both the entire tar archive and the original files - and therefore it is not possible to simply manually delete the files after creating an archive in the usual way. 回答1: With GNU tar, use the option --remove-files . 回答2: I had a task - archive files and then remove into OS installed "tar" without GNU-options. Method: Use "xargs" Suppose, we are have a

How to compare two tarball's content

由 落爺英雄遲暮 提交于 2019-12-03 05:34:14
问题 I want to tell whether two tarball files contain identical files, in terms of file name and file content, not including meta-data like date, user, group. However, There are some restrictions: first, I have no control of whether the meta-data is included when making the tar file, actually, the tar file always contains meta-data, so directly diff the two tar files doesn't work. Second, since some tar files are so large that I cannot afford to untar them in to a temp directory and diff the
