os.remove() removes a file. os.rmdir() removes an empty directory. shutil.rmtree() deletes a directory and all its contents. Path objects from the Python 3.4+ pathlib module also expose these instance methods: pathlib.Path.unlink() removes a file or symbolic link. pathlib.Path.rmdir() removes an empty directory.
On Python ≥ 3.5, use pathlib.Path.mkdir: from pathlib import Path Path(“/my/directory”).mkdir(parents=True, exist_ok=True) For older versions of Python, I see two answers with good qualities, each with a small flaw, so I will give my take on it: Try os.path.exists, and consider os.makedirs for the creation. import os if not os.path.exists(directory): os.makedirs(directory) As noted in comments … Read more
Do the following: grep -rnw ‘/path/to/somewhere/’ -e ‘pattern’ -r or -R is recursive, -n is line number, and -w stands for match the whole word. -l (lower-case L) can be added to just give the file name of matching files. -e is the pattern used during the search Along with these, –exclude, –include, –exclude-dir flags … Read more
Try this iterator block version that avoids recursion and the Info objects: public static IEnumerable<string> GetFileList(string fileSearchPattern, string rootFolderPath) { Queue<string> pending = new Queue<string>(); pending.Enqueue(rootFolderPath); string[] tmp; while (pending.Count > 0) { rootFolderPath = pending.Dequeue(); try { tmp = Directory.GetFiles(rootFolderPath, fileSearchPattern); } catch (UnauthorizedAccessException) { continue; } for (int i = 0; i < … Read more
find . -mindepth 1 -maxdepth 1 -not -empty -type d will give you all nonempty directories. If you want to exclude directories that contain only other directories (but no files), one of the other answers might be better…
This one should do it: get-childitem -Include .svn -Recurse -force | Remove-Item -Force -Recurse Other version: $fso = New-Object -com “Scripting.FileSystemObject” $folder = $fso.GetFolder(“C:\Test\”) foreach ($subfolder in $folder.SubFolders) { If ($subfolder.Name -like “*.svn”) { remove-item $subfolder.Path -Verbose } }
var di = new DirectoryInfo(“SomeFolder”); di.Attributes &= ~FileAttributes.ReadOnly;
The URI class is useful for working with relative paths. File mydir = new File(“C:\\mydir”); File myfile = new File(“C:\\mydir\\path\\myfile.txt”); System.out.println(mydir.toURI().relativize(myfile.toURI()).getPath()); The above code will emit the string path/myfile.txt. For completeness, here is a zip method for archiving a directory: public static void zip(File directory, File zipfile) throws IOException { URI base = directory.toURI(); Deque<File> … Read more
You need to first create the directory. The mkdir -p implementation from this answer will do just what you want. mkdir -p will create any parent directories as required, and silently do nothing if it already exists. Here I’ve implemented a safe_open_w() method which calls mkdir_p on the directory part of the path, before opening … Read more
The lib directory, for most of my projects, is where I place shared components that might be used in multiple facets of my application. Things in this folder should not be tightly coupled to your application, and should theoretically be able to be plucked from one project to another, and work as expected (assuming all … Read more
