Aðgangsheimildir

All of the files on a Linux system have permissions that allow or prevent others from viewing, modifying or executing them. The superuser "root" has the ability to access any file on the system. Each file has access restrictions, user restrictions, and an owner/group association.

Allar skrár eru verndaðar þremur lögum af heimildum:

notandi

Á við notandann sem er eigandi skráarinnar

hópur

Á við hópinn sem skráin tilheyrir

annað

Á við um alla notendur

Inside each of the three sets of permissions are the actual permissions. The permissions, along with the way they apply differently to files and directories, are outlined below:

lestur

Skrár eða möppur sem eingöngu er hægt að skoða.

breyting

Skrár eða möppur sem má breyta eða eyða

keyra

Skrár sem er hægt að keyra sem forrit eða möppur sem má fara inn í.

To view and edit the permissions on files and directories, first open Konqueror in file manager mode by selecting Home Folder from the System Menu located next to the KMenu icon in the bottom left corner of your display. To display the dialog to allow permission editing, right click on a file or directory, then select Properties. The permissions are found under the Permissions tab and allow for the editing of all permission levels, if you are the owner of the file.
