In addition to the many standard Unix tools Be has included in /boot/beos/bin, there are also a couple of custom tools that make it easy to view and change a file’s attributes.

To view a file’s attributes from the Terminal, type listattr filename.

However, this will only show you the byte size, name, and type of the attributes. It won’t show you its value (contents). To see contents, use the Tracker Add-On AttributeViewer. To add attributes to a file type addattr fieldname value filename

For example: addattr huey duey foobar will add an attribute named “huey” with a value of “duey” to a file called foobar. To remove attributes, use: rmattr fieldname filename. You can get more details on usage by typing addattr –help .
