Frequently Asked Questions

Can files have more than one filename?

University of Utah Mathematics Department FAQ: Files
Please note the difference between move (mv) and link (ln). After a move, there is only one instance of the file, but after a link, there is still one instance, but now there are two names for the same file. Removing one of the links leaves the file intact under its other name(s). requires that the files be on the same filesystem, and creates a hard link. Editing one of them may preserve the link, or break it: see the Classic Shell Scripting citation above for details.

How do I change the case of a filename?

subversion: Subversion FAQ
This problem comes up in two situations. If you're adding files on an operating system with a case-insensitive filesystem, such as Windows, you might find you accidentally add a file with the wrong case in the filename. Alternatively, you may just decide to change the case of an existing file in the repository. If you're working in a case-sensitive file system, this is no problem at all. Just move the file to the new name, e.g., svn mv file.java File.

What's the standard filename extension for a reStructuredText file?

Docutils FAQ (Frequently Asked Questions)
It's ".txt". Some people would like to use ".rest" or ".rst" or ".restx", but why bother? ReStructuredText source files are meant to be readable as plaintext, and most operating systems already associate ".txt" with text files. Using a specialized filename extension would require that users alter their OS settings, which is something that many users will not be willing or able to do.

Q3.9: How do I dynamically generate a filename for SAVE?

This is also useful in commands like PRINT, LOAD, CLEAR, etc.

What is a filename extension?

Help with Applying Online - Arts Opportunities
A filename extension can be found at the end of a filename (i.e. resume.doc). The extension indicates what type of file it is (.doc indicated this file is a Microsoft Word file). On PCs, filename extensions are added automatically, although they will only be visible if you have that setting selected in the "detail view" on your PC. If you work on a Mac and are using a word processing program, you will need to manually enter a filename extension when you name and save your file.

Why and how to zero-fill a filename?

CCC - Canadian Guide to the Uniform Preparation of Judgments...
The Guide gives courts the option of zero-filling the number that corresponds to the sequence number of the neutral citation in the filename. This technique allows for easier sorting of files in the ascending or descending order of their sequence number in electronic directories. For instance, here are three judgments for which the core of citation is respectively 2002 ONCA 4, 2002 ONCA 551 and 2002 ONCA 2456.

Why can't I have the same filename in two different categories?

codejedi.com - Home of Shadow Plan for Palm OS
Palm OS only allows about 30 characters in a filename. I have to put something unique at the beginning of the filename, to make sure they don't get clobbered by some other program, and to make everyones life easier recognizing who built what. A category can be pretty long, too. So if I stucked the category name into the filename, to allow unique filenames in a category, you'd only have a very small filename allowed. We like big filenames.

Can I do filename globbing with DJGPP?

DJGPP Frequently-Asked Questions List
A : The filename globbing in DJGPP is done by the start-up code, before your main function is called. Unlike other DOS-based compilers, where you must link your program with a special object module if you want the program to get expanded filenames, in DJGPP this is considered normal behavior and performed by default on behalf of every DJGPP program. The x*y above was expanded to a file called xyzzy which was probably present in the current working directory.
