TOPS-20 Commands Reference Manual

END-ACCESS

Terminates your ownership rights to an accessed directory, as well as group rights borrowed from its owner.

Format

@END-ACCESS (TO DIRECTORY) dev:<directory>

where:

dev:<directory> is the directory to which you want to end access.
Default dev: your connected structure
Default <directory> the directory (on the specified structure) of the same name as your connected directory

Hints

Implicit END-ACCESS

You can access only one directory at a time on each mounted structure. Each ACCESS command ends access obtained by any previous ACCESS command for a directory on the specified structure. Therefore you do not need to give the END-ACCESS command if you access another directory on the structure, or if the structure is dismounted.

Restoring Previous Rights

END-ACCESS does not restore owner and group rights obtained by a previous ACCESS command for the specified structure. Give another ACCESS command to regain these. (Note that you must access your log-in directory to regain group rights obtained by the LOGIN command, lost by accessing another directory on the public structure.

Related Commands

Examples

  • Give up your access rights to another user's directory. 
    @END-ACCESS <HOLLAND>
  • Access another user's directory, copy a file from it, and give up your rights to it. Then give a command that depends on your own group rights. (It fails.) Access your own directory to establish these, and repeat the command, successfully this time.
