This works fine: os.path.join(dir_name, base_filename + ‘.’ + filename_suffix) Keep in mind that os.path.join() exists only because different operating systems use different path separator characters. It smooths over that difference so cross-platform code doesn’t have to be cluttered with special cases for each OS. There is no need to do this for file name “extensions” … Read more
To rename the file you can use the standard git mv command. Since Windows treats files with only changes in case as identical, you have to pass the -f option to force a rename: git mv -f name.java Name.java If instead you want to ignore case changes, have a look at the question How to … Read more
You’re looking for basename. The example from the PHP manual: <?php $path = “/home/httpd/html/index.php”; $file = basename($path); // $file is set to “index.php” $file = basename($path, “.php”); // $file is set to “index” ?>
Individual components of a filename (i.e. each subdirectory along the path, and the final filename) are limited to 255 characters, and the total path length is limited to approximately 32,000 characters. However, on Windows, you can’t exceed MAX_PATH value (259 characters for files, 248 for folders). See http://msdn.microsoft.com/en-us/library/aa365247.aspx for full details.
I think your search for a “standard” naming convention will be in vain. Here are my proposals, based on existing, well-known programs: A) C:\users\OddThinking\Documents\My Source\Widget\foo.src — Vim calls it file root (:help filename-modifiers) B) C:\users\OddThinking\Documents\My Source\Widget\foo.src ——- file name or base name C) C:\users\OddThinking\Documents\My Source\Widget\foo.src ___ (without dot) file/name extension D) C:\users\OddThinking\Documents\My Source\Widget\foo.src ____ (with … Read more
just use File.getName() File f = new File(“C:\\Hello\\AnotherFolder\\The File Name.PDF”); System.out.println(f.getName()); using String methods: File f = new File(“C:\\Hello\\AnotherFolder\\The File Name.PDF”); System.out.println(f.getAbsolutePath().substring(f.getAbsolutePath().lastIndexOf(“\\”)+1));
Path.GetFileName Returns the file name and extension of a file path that is represented by a read-only character span. Path.GetFileNameWithoutExtension Returns the file name without the extension of a file path that is represented by a read-only character span. The Path class is wonderful.
Historically, the first extensions used for C++ were .c and .h, exactly like for C. This caused practical problems, especially the .c which didn’t allow build systems to easily differentiate C++ and C files. Unix, on which C++ has been developed, has case sensitive file systems. So some used .C for C++ files. Other used … Read more
I use: for f in *\ *; do mv “$f” “${f// /_}”; done Though it’s not recursive, it’s quite fast and simple. I’m sure someone here could update it to be recursive. The ${f// /_} part utilizes bash’s parameter expansion mechanism to replace a pattern within a parameter with supplied string. The relevant syntax is … Read more
You can look at the Django framework for how they create a “slug” from arbitrary text. A slug is URL- and filename- friendly. The Django text utils define a function, slugify(), that’s probably the gold standard for this kind of thing. Essentially, their code is the following. import unicodedata import re def slugify(value, allow_unicode=False): “”” … Read more
