copied!<p>Here is a Python script that I've put together. It's had minimal testing so far. I've done basic testing in Python 2.6. But I prefer the idea of Python in general because it should abort with an exception if any error occurs, whereas a bash script may not.</p> <p>This first checks that the input file is valid and not already uncompressed. Then it copies the input file to a "backup" file with ".bak" extension. Then it uncompresses the original file, overwriting it.</p> <p>I'm sure there are things I've overlooked. Please feel free to give feedback.</p> <pre class="lang-python prettyprint-override"><code> #!/usr/bin/python # Note, written for Python 2.6 import sys import shutil import zipfile # Get a single command-line argument containing filename commandlineFileName = sys.argv[1] backupFileName = commandlineFileName + ".bak" inFileName = backupFileName outFileName = commandlineFileName checkFilename = commandlineFileName # Check input file # First, check it is valid (not corrupted) checkZipFile = zipfile.ZipFile(checkFilename) checkZipFile.testzip() # Second, check that it's not already uncompressed isCompressed = False for fileObject in checkZipFile.infolist(): if fileObject.compress_type != zipfile.ZIP_STORED: isCompressed = True if isCompressed == False: raise Exception("File is already uncompressed") checkZipFile.close() # Copy to "backup" file and use that as the input shutil.copy(commandlineFileName, backupFileName) inputZipFile = zipfile.ZipFile(inFileName) outputZipFile = zipfile.ZipFile(outFileName, "w", zipfile.ZIP_STORED) # Copy each input file's data to output, making sure it's uncompressed for fileObject in inputZipFile.infolist(): fileData = inputZipFile.read(fileObject) outFileObject = fileObject outFileObject.compress_type = zipfile.ZIP_STORED outputZipFile.writestr(outFileObject, fileData) outputZipFile.close() </code></pre> <p>This is in a <a href="http://bitbucket.org/cmcqueen1975/odf_uncompress" rel="nofollow noreferrer">Mercurial repository in BitBucket</a>.</p>
