Modifying files nested in tar archive

阅读更多关于 Modifying files nested in tar archive

问题 I am trying to do a grep and then a sed to search for specific strings inside files, which are inside multiple tars, all inside one master tar archive. Right now, I modify the files by First extracting the master tar archive. Then extracting all the tars inside it. Then doing a recursive grep and then sed to replace a specific string in files. Finally packaging everything again into tar archives, and all the archives inside the master archive. Pretty tedious. How do I do this automatically

阅读更多关于 excluding some folders in tar command not work

问题 I run this command to compress the content of current folder while excluding some directories: mahmood@mpc:set3-HHLL$ l file1.txt a/ c/ file2.inp b/ ... mahmood@mpc:set3-HHLL$ tar cvjf ../set3.tar.bz2 * --exclude=a/ --exclude=b/ --exclude=c/ However in the output I see: file1.txt file2.inp a/1.out a/2.out 2/1.out ... Why it ignores the command line options? 回答1: The correct command would be: tar cvjf ../set3.tar.bz2 * --exclude='a' --exclude='b' --exclude='c' 来源： https://stackoverflow.com

having cv2.imread reading images from file objects or memory-stream-like data (here non-extracted tar)

阅读更多关于 having cv2.imread reading images from file objects or memory-stream-like data (here non-extracted tar)

问题 I have a .tar file containing several hundreds of pictures ( .png ). I need to process them via opencv. I am wondering whether - for efficiency reasons - it is possible to process them without passing by the disc. In other, words I want to read the pictures from the memory stream related to the tar file. Consider for instance import tarfile import cv2 tar0 = tarfile.open('mytar.tar') im = cv2.imread( tar0.extractfile('fname.png').read() ) The last line doesn't work as imread expects a file

How to untargz files using maven?

阅读更多关于 How to untargz files using maven?

问题 Using maven, I download some Chef cookbooks. Received files are in the .tgz format, and I want to unpack them. How can I do that ? Is there any useful plugin ? 回答1: From what I know, .tgz can be unpack via two commands: gzip -d file.tgz tar xvf file.tar So you can use maven-antrun-plugin to execute these two tasks: <gunzip src="tools.tgz"/> <untar src="tools.tar" dest="${tools.home}"/> Ant task reference: gunzip and untar 回答2: I would suggest to use the truezip-maven-plugin to handle such

Organizing files in tar bz2 file with python

阅读更多关于 Organizing files in tar bz2 file with python

问题 I have about 200,000 text files that are placed in a bz2 file. The issue I have is that when I scan the bz2 file to extract the data I need, it goes extremely slow. It has to look through the entire bz2 file to fine the single file I am looking for. Is there anyway to speed this up? Also, I thought about possibly organizing the files in the tar.bz2 so I can instead have it know where to look. Is there anyway to organize files that are put into a bz2? More Info/Edit: I need to query the
