ATTRIB is a small command line application that allows you to view and edit file attributes.For each event ATTRIB returns an appropriate exit code which can be used in "if errorlevel" statements in batch files: 0 completion successful; /? option used. 1 error to change attribute(s) of file(s). 2 no matching file(s) found for target(s). 3 error open file(s), pointed in /@ option(s). 4 error(s) in command line.Higher errorlevels should absorb lower errorlevels (for example, if there are errors to change attributes and no matching targets for other argument, then 2 will be returned).
