open

(1)
To prepare to read or write a file. This usually involves checking whether the file already exists and that the user has the necessary authorisation to read or write it. The result of a successful open is usually some kind of capability (e.g. a Unix file descriptor) - a token that the user passes back to the system in order to access the file without further checks and finally to close the file.

open

(1) To engage a file for reading and writing. Technically, an app is "run" and the data file is "opened." For example, after a word processing application is "loaded and run," a document is "opened" for editing or printing. Then, the document is "closed," and the app is "exited." Apps are also said to be "opened" and "closed."

In the case of a script or batch file, "open" can mean "open" for editing or "open and run." The difference is significant. Opening a batch file to edit its contents causes no action until the user makes changes, whereas opening and running a batch file causes instructions to be executed. Contrast with close.

(2) To "run" a program (application). "Open" is increasingly used to mean "load and run."

(3) With regard to a switch, open is "off." See switch.

(4) Made to operate or function compatibly with other products. See open architecture, open system and open source.
