Python script to delete old SVN files lacks permission
- by Rosarch
I'm trying to delete old SVN files from directory tree. shutil.rmtree and os.unlink raise WindowsErrors, because the script doesn't have permissions to delete them. How can I get around that?
Here is the script:
# Delete all files of a certain type from a direcotry
import os
import shutil
dir = "c:\\"
verbosity = 0;
def printCleanMsg(dir_path):
if verbosity:
print "Cleaning %s\n" % dir_path
def cleandir(dir_path):
printCleanMsg(dir_path)
toDelete = []
dirwalk = os.walk(dir_path)
for root, dirs, files in dirwalk:
printCleanMsg(root)
toDelete.extend([root + os.sep + dir for dir in dirs if '.svn' == dir])
toDelete.extend([root + os.sep + file for file in files if 'svn' in file])
print "Items to be deleted:"
for candidate in toDelete:
print candidate
print "Delete all %d items? [y|n]" % len(toDelete)
choice = raw_input()
if choice == 'y':
deleted = 0
for filedir in toDelete:
if os.path.exists(filedir): # could have been deleted already by rmtree
try:
if os.path.isdir(filedir):
shutil.rmtree(filedir)
else:
os.unlink(filedir)
deleted += 1
except WindowsError:
print "WindowsError: Couldn't delete '%s'" % filedir
print "\nDeleted %d/%d files." % (deleted, len(toDelete))
exit()
if __name__ == "__main__":
cleandir(dir)
Not a single file is able to be deleted. What am I doing wrong?
