Take a look at dictzip. It is compatible with gzip and allows coarse random access. An excerpt from its man page: dictzip compresses files using the gzip(1) algorithm (LZ77) in a manner which is completely compatible with the gzip file format. An extension to the gzip file format (Extra Field, described in 2.3.1.1 of RFC … Read more
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
This answer changes with .NET 4.5. Creating a zip file becomes incredibly easy. No third-party libraries will be required. string startPath = @”c:\example\start”; string zipPath = @”c:\example\result.zip”; string extractPath = @”c:\example\extract”; ZipFile.CreateFromDirectory(startPath, zipPath); ZipFile.ExtractToDirectory(zipPath, extractPath);
objdump seems like the best way: objdump -f libfoo.a | grep ^architecture
bzip and gzip work on single files, not groups of files. Plain old zip (and pkzip) operate on groups of files and have the concept of the archive built-in. The *nix philosophy is one of the small tools that do specific jobs very well and can be chained together. That’s why there are two tools … Read more
According to the Python docs: class zipfile.ZipFile(file[, mode[, compression[, allowZip64]]]) Open a ZIP file, where file can be either a path to a file (a string) or a file-like object. So, to open the file in memory, just create a file-like object (perhaps using BytesIO). file_like_object = io.BytesIO(my_zip_data) zipfile_ob = zipfile.ZipFile(file_like_object)
The extention .zst means that the archive is compressed by zstd. https://github.com/facebook/zstd The tar command has an option -I (–use-compress-program) to specify a command for compression/decompression. You can use it as follows. $ tar –use-compress-program=unzstd -xvf archive.tar.zst
Your understanding is correct, an artifact in the Jenkins sense is the result of a build – the intended output of the build process. A common convention is to put the result of a build into a build, target or bin directory. The Jenkins archiver can use globs (target/*.jar) to easily pick up the right … Read more
Use the -J compression option for xz. And remember to man tar 🙂 tar cfJ <archive.tar.xz> <files> Edit 2015-08-10: If you’re passing the arguments to tar with dashes (ex: tar -cf as opposed to tar cf), then the -f option must come last, since it specifies the filename (thanks to @A-B-B for pointing that out!). … Read more
Yes: tar -cvf allfiles.tar -T mylist.txt
