In Unix-like operating systems, unlink is a system call and a command line utility to delete files. The program directly interfaces the system call, which removes the file name and (but not on GNU systems) directories like rm and rmdir. [1] If the file name was the last hard link to the file, the file itself is deleted as soon as no program has ...
Using rd/rmdir and two directories with the same name and different case sensitivities exist, one of which contains valid data and/or programs, and the other contains incriminating materials and/or malware. If rd/rmdir gets executed without regard to case sensitivity and Windows chooses the legitimate folder to delete, the only folder left is ...

Recursive selection - loads files in directory and in subdirectories. Undo an operation. Wide use of regular expressions: when selecting items, for search/replace, etc.. Reading of metadata such as ID3 and Exif tags, or creation/modification/last access time. Change length of names. Change case in various ways.
Only the oldest backups can be removed, with rdiff-backup --remove-older-than <date> <backup directory>. The ability to delete the oldest versions of specific files (or directories) is scheduled to appear in version 2.2. When deleting old versions, <date> takes the same arguments as when restoring files or directories (see above).
A classic example of recursion is the definition of the factorial function, given here in Python code: def factorial ( n ): if n > 0 : return n * factorial ( n - 1 ) else : return 1 The function calls itself recursively on a smaller version of the input (n - 1) and multiplies the result of the recursive call by n , until reaching the base case ...
Since the same files and directories can now be encountered through multiple paths, applications which traverse reentrant or recursive structures naively may give incorrect or incoherent results, or may never terminate. Worse, if recursively deleting, such programs may attempt to delete a parent of the directory it is currently traversing.
Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. [32] Python is dynamically type-checked and garbage-collected. It supports multiple programming paradigms, including structured (particularly procedural), object-oriented and functional ...
