Assigning file attributes to variables
Hi,

I'm trying to assign the permissions, owner and group of a file to seperate variables, but using

ls -l filename | awk '{print $1 "\t" $3 "\t" $4}'

gives the owner as tom.ja instead of tom.james
Is there any way to expand it so i get the full name, or is there an easier way to get them into variables?

Also, i'm processing the permissions into a table ie Owner has READ and EXECUTE permissions, Group has... etc. I was thinking to use a shift to deal with each permission, is there any way to now seperate each permission? ie.
-rwxr-x-r-- into
- r w x r - x - r - -
it doesn't have to be whitespace, but just so i can process each one.


Thanks

Oliver

Before I even attempt this, is it possible to grep for a pattern, maybe a partial sentence like "go to page 3", assign that to a variable and then use awk or something to pull out the 3 and assign it to a variable? So first I would have Gotopg = "go to page 3" then page = 3 (9 Replies)

nischmod

nischmod(1)							   User Commands						       nischmod(1)

NAME

       nischmod - change access rights on a NIS+ object

SYNOPSIS

       nischmod [-AfLP] mode name...

DESCRIPTION

       nischmod  changes  the  access rights (mode) of the NIS+ objects or entries specified by  name to mode. Entries are specified using indexed
       names (see nismatch(1)). Only principals with modify access to an object may change its mode.

       mode has the following form:

	      rights [, rights]...

       rights has the form:

       [ who ] op permission [ op permission ]...

       who is a combination of:

       n	Nobody's permissions.

       o	Owner's permissions.

       g	Group's permissions.

       w	World's permissions.

       a	All, or  owg.

		If  who is omitted, the default is  a.

       op is one of:

       +	       To grant the  permission.

       -	       To revoke the  permission.

       =	       To set the permissions explicitly.

       permission is any combination of:

       r	Read.

       m	Modify.

       c	Create.

       d	Destroy.

       Unlike the system chmod(1) command, this command does not accept an octal notation.

OPTIONS

       The following options are supported:

       -A	Modify all entries in all tables in the concatenation path that match the search criteria specified in name. This  option  implies
		the -P switch.

       -f	Force the operation and fail silently if it does not succeed.

       -L	Follow links and change the permission of the linked object or entries rather than the permission of the link itself.

       -P	Follow	the  concatenation path within a named table. This option is only applicable when either name is an indexed name or the -L
		switch is also specified and the named object is a link pointing to an entry.

EXAMPLES

       Example 1: Using the nischmod Command

       This example gives everyone read access to an object. (that is, access for owner, group, and all).

       example% nischmod a+r object

       This example denies create and modify privileges to  group and unauthenticated clients (nobody).

       example% nischmod gn-cm object

       In this example, a complex set of permissions are set for an object.

       example% nischmod o=rmcd,g=rm,w=rc,n=r object

       This example sets the permissions of an entry in the password table so that the group owner can modify them.

       example% nischmod g+m '[uid=55],passwd.org_dir'

       The next example changes the permissions of a linked object.

       example% nischmod -L w+mr linkname

ENVIRONMENT VARIABLES

       NIS_PATH 		       If this variable is set, and the NIS+ name is  not  fully  qualified,  each  directory  specified  will	be
				       searched until the object is found (see	nisdefaults(1)).

EXIT STATUS

       The following exit values are returned:

       0	Successful operation.

       1	Operation failed.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Availability		     |SUNWnisu			   |
       +-----------------------------+-----------------------------+

SEE ALSO

       chmod(1), nis+(1), nischgrp(1), nischown(1), nisdefaults(1), nismatch(1), nis_objects(3NSL), attributes(5)

NOTES

       NIS+  might  not  be  supported in future releases of the SolarisTM Operating Environment. Tools to aid the migration from NIS+ to LDAP are
       available in the Solaris 9 operating environment. For more information, visit http://www.sun.com/directory/nisplus/transition.html.
