Hi all,
Would like to search list of directories with specific pattern and
delete it?.. How can i do it?.
Example: in /home/jpr/ i have the following list of directories.
1.2.3-2, 1.2.3-10, 1.2.3-8, i would like to delete the directories
other than 1.2.3-10 which is the higher value?..
Use os.listdir to get a list of the names in the directory.
Use os.path.isdir to identify those which are subdirectories.
Identify the names which match the pattern, eg:
name.startswith(1.2.3-) and name[6 : ].isdigit()
Identify the 'highest' name (it's the one with the maximum value of
int(name[6 : ])).
Remove each of the unwanted subdirectories with shutil.rmtree.
It's also a good idea if initially it doesn't actually remove the
unwanted directories, but just prints out the paths of them, because
you really don't want to discover that you've made a mistake and it has
deleted something important! :-)
