Write
Write may refer to any of the following:
1. When referring to data or a storage device, writing is the process of taking information and moving it to an alternate location. For example, saving data onto a diskette is the same as writing information to a diskette.
Almost all forms of media are writable, which means any information can be written to it. However, if a disk is write protected, or you don't have permission to write to the media, you will receive a write error when attempting to write information to that disk.
2. Linux command, see the write command page for further information.
3. In general, write is a term may that describes the action of typing text. For example, when you type text into a search engine, such as Google, you are "writing" in your search query.
4. When dealing with permissions or security, write is a setting that gives the user or the computer the ability to write to a file. For example, if a file is set as read-only the computer does not have the write privilege and would not be able to edit or make changes to a file.
In MS-DOS and the Windows command line, a file can be made read-only by using the attrib command. In Linux, the write attribute can be adjusted using the chmod command.
