.. (dot-dot) is a special notation used in computing and programming to represent a relative path. It is typically used to refer to the parent directory of the current working directory. Relative Path When navigating a file system, the current working directory (CWD) is the starting point for all file and directory operations. A relative path is a path that specifies the location of a file or directory relative to the CWD. Dot-Dot Notation The .. notation represents the parent directory of the CWD. For example, if the CWD is /home/user/documents, then /home/user is the parent directory. Usage Dot-dot notation can be used in various commands and scripts to navigate the file system: * cd ..: Change directory to the parent directory. * ls -d ../: List the contents of the parent directory. * mkdir ../newdir: Create a new directory in the parent directory. Absolute Path An absolute path starts from the root directory (/) and specifies the exact location of a file or directory. It does not use .. notation. For example, /home/user/documents is an absolute path. Linux and Windows In both Linux and Windows operating systems, .. notation is used to refer to the parent directory. However, the path separators differ: * Linux uses forward slash (/) as the path separator (e.g., /home/user/documents). * Windows uses backslash () as the path separator (e.g., C:homeuserdocuments). Shortcuts In certain contexts, .. notation can be used as a shortcut to refer to the current directory (.): * **cd ..;: Change directory to the parent directory. * **ls -d .: List the contents of the current directory. * **mkdir ./: Create a new directory in the current directory. Note: .. notation should not be confused with the wildcard character *, which represents any number of characters in a file or directory name…. (Ellipsis)
... (Ellipsis) Ellipsis, denoted by the three dots “…”, is a punctuation mark used in writing to indicate the omission of words or phrases. It serves various purposes: Omission of Text: * To condense long passages by removing unnecessary details without altering the meaning. * To create a sense of intrigue or suspense by leaving out crucial information. * To indicate a trailing off or unfinished thought. Example: “He opened the door and stepped inside… The darkness enveloped him like a suffocating blanket.” Pause or Hesitation: * To convey a pause in speech or thought. * To indicate a gradual transition or shift in tone. * To express uncertainty or doubt. Example: “I’m not sure… maybe I should tell him the truth.” Emphasis and Climax: * To emphasize the significance of a word or phrase. * To build anticipation or suspense leading up to a climax. * To suggest an unspoken or implied meaning. Example: “He knows… he knows everything.” Other Uses: * To represent a series of dots or periods. * To indicate a fade-out or gradual decrease in sound or volume. * To denote an interval or range of time or numbers. Example: “The temperature hovered around… 70 degrees Fahrenheit.” Usage Guidelines: * Use ellipsis sparingly to avoid ambiguity or confusion. * Enclose the omission in three dots, with no spaces between them. * Use conservative spacing around the ellipsis (one space before and after). * Avoid using ellipsis before or after quotation marks, unless intended for emphasis.
