Setting File and Directory Access Permissions

To review or change the permissions set for files and directories on Linux systems:

1. Go to Files.

   The permissions set for files and directories are shown in the Permissions column. They are represented as three sets of symbols, for example, 'rwx rwx r--'. The first set tells what the owner of the file or directory can do with it; the second tells what the user group, the file or directory belongs to, can do with the file or directory; the third set indicates what other users (the rest of the world, that is, Internet users visiting a site) can do with the file or directory. R means the permission to read the file or directory, W means the permission to write to the file or directory, and X means the permission to execute the file or look inside the directory.

2. Locate the file or directory for which you want to modify permissions and click a hyperlink in the Permissions column.
3. Modify the permissions as desired and click OK.
