>From "ls -l" command. -rwxrwxrwx
First character, the dash in this case, identifies the kind of file (in Unix everything is a file). The next three are the owner's permissions. The next three are the group's permissions. The next three are the world's permissions. r=read w=write x=execute These mean different things for plain files and directories. For directory: r=you can list the contents of the directory w=you can change the contents of the directory; i.e. create, delete, and rename files. x=you can cd into the directory or one of its subdirectories. More generically speaking, the directory can be part of a path in a command. So, for a user to be able to delete files, the user needs AT LEAST write and execute permission. If the user does not have read permission, then the user can still manipulate files in the directory, but they can't list what's in the directory; so the user will be working blind. This is (or was) used by some software services to put patches, etc. on a FTP box and allow anonymous connections. Unless you knew the name of the file you were supposed to get, you couldn't get the file; and the software support had to tell you name of the file. chmod 755 on a directory sets the permissions to: drwxr-xr-x which means only the owner can modify the contents of the directory. chmod 777; or chmod a+rwx; or chmod ugo+rwx will set permission to: drwxrwxrwx In general, sys admins don't like to see this. I hope this little discussion increases your appreciation for the loveliness of non-MS OS. > -----Original Message----- > > anyone whom could help me with a unix command how to > give permission to delete files from a special directory? > > I am trying to use chmod command but it doesnt work with chmod 755 > It says permission denied then. > -- Please see the official ORACLE-L FAQ: http://www.orafaq.net -- Author: Stephen Lee INET: [EMAIL PROTECTED] Fat City Network Services -- 858-538-5051 http://www.fatcity.com San Diego, California -- Mailing list and web hosting services --------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB ORACLE-L (or the name of mailing list you want to be removed from).
