问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 5 years ago . I'm working on a commercial project that requires a couple of files to be bundled (packed) into an archive and then compressed. Right now we have zlib in our utility library, but it doesn't look like zlib has the functionality to compress multiple files into one archive. Does

Create a tar.xz in one command

问题 I am trying to create a .tar.xz compressed archive in one command. What is the specific syntax for that? I have tried tar cf - file | xz file.tar.xz , but that does not work. 回答1: 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!).

由 流过昼夜 提交于 2020-01-11 07:12:06

Is there any documentation on

Can I re-open .xcarchive on Xcode?

问题 Is it possible to re-open an .xcarchive file on Xcode? I know this is not common, but I would like to open a project exactly as it was submitted to the App Store. I don't have back up of that exact build, so it would be really great to open the archive copy! Before you ask why don't I just download it from the store, I must say this build has been approved and is just pending on my release. :) Thanks! 回答1: A xcarchive is a folder containing a (compiled) app bundle, a dSYM (debug file) for the

问题 Is there a library for crating/extracting zip files in php? The ZipArchive class works erratically, and this is mentioned on php.net : (for every function I checked) ZipArchive::addEmptyDir (No version information available, might be only in CVS) 回答1: Check PEAR Archive_Zip it might help you http://pear.php.net/package/Archive_Zip/docs/latest/Archive_Zip/Archive_Zip.html 回答2: PHP has native Zip support via GZip (may not be enabled by default): http://php.net/zlib You can also use this class

Does lipo increase final binary size?

由 半腔热情 提交于 2020-01-06 08:16:29
