If you type ls **, or ls *.txt, the ls command itself never sees the * characters it only sees an expanded list of files matching the pattern, just as if you had typed the entire list on the command line.īy using the double asterisk ( **), you are using a glob to list files on a filesystem. It's important to keep in mind that wildcards are expanded by the shell, not by the ls command. In recent versions of bash the 'globstar' shell option is disabled by default. If followed by a '/', two adjacent '*'s will match only

Match all files and zero or more directories and subdirectories. 'globstar' shell option is enabled, and '*' is used in a filenameĮxpansion context, two adjacent '*'s used as a single pattern will Matches any string, including the null string. You should look at the wildcard matching rules for your shell to know for sure what your shell is doing. txt files no matter what subdirectory they are in with **/*.txt, whereas *.txt only matches those in the current directory. **'s real power comes when you use it in more specific patterns. (In both cases 'dot files', those with names starting with. If you do not have such a shell, ** will likely be equivalent to *, because 'matching zero or more characters followed by zero or more characters' is the same as just 'matching zero or more characters'.īut if you do have such a shell, ** will match all files and directories in the current directory and subdirectories, whereas * only matches files and directories in the current directory. For example, installing and enabling the DoubleCommand application allows the user to use the Backslash, Capslock or numeric keypad ↵ Enter keys as a forward delete key.You're most likely seeing a special feature of some shells that allow wildcard filename patterns to match across directory boundaries, as opposed to a single *, which is a wildcard that matches only within a directory.

In other GUI contexts, the Undo function can often reverse a deletion.Īs many Apple keyboards lack a dedicated key for the forward delete function, Mac users wishing to have a dedicated forward delete key can reassign the forward-delete function to a different key using various third-party applications, such as DoubleCommand, Karabiner or PowerKey. In GUI applications where the Delete key is enabled, especially in file browsers, pressing it does not necessarily immediately delete the selected object, but often a confirmation dialog box will appear to allow the user to cancel the deletion, or the object may instead be silently moved to a ' trash folder' or equivalent, so that it can be recovered later. The delete key, on many modern motherboards, also functions to open the BIOS setup screen when pressed after starting the computer. On Unix-like systems, the delete key is usually mapped to ESC

On Apple Keyboards, both the forward delete key and the delete (backspace) key have the same effect when pressed while an object is selected. The delete key often works as a generic command to remove a selected object, such as an image embedded in a document. The key is also used by many GUI applications to request deletion of the currently-selected object, for example a file in a file browser or a block of text in a word processor. When struck on a computer keyboard during text or command editing, the delete key ( Delete or Del), known less ambiguously as forward delete, discards the character ahead of the cursor's position, moving all following characters one position 'back' towards the freed letterspace. On some compact keyboards (for example, the 60-key Happy Hacking Keyboard), the Delete key replaces the conventional Backspace key, and the Backspace function is achieved by holding the Fn key and pressing Delete. The Delete key is typically smaller and less-conveniently located than the Backspace key, and on keyboards where space is limited, for example those omitting the numeric keypad or virtual keyboards on mobile devices, it is often omitted altogether. On a MacBook, the forward delete function can be achieved using the Fn+ ← Backspace key combination or simply Control+ D. On this row of smaller keys, the position of the Delete key is positioned at or near the right-hand end. Many laptops add rows of smaller keys above the Function key line to add keys on a non-standard size keyboard. In other cases, the Delete key is in its original IBM notebook position of above and to the right of the Backspace key. However, sometimes the key labelled Delete performs the Backspace function instead, for example on some Apple keyboards. A dedicated symbol for 'delete' exists as U+2326 ⌦ but its use as a keyboard label is not universal.

The key appears on English-language IBM-compatible PC keyboards labeled as Delete or Del, sometimes accompanied by a crossed-out right-arrow symbol.
