Hello newbie_01,

You could add the variable directly into the .profile as follows, I tried in bash and it worked successfully for me.
Off course use a new session for server after adding this to .profile to make alias effective.
Code:
X=`df -k /tmp | awk 'NR==1 {CNV=1024*1024;GBYTES="GBytes";FMT="%-35s %-10s %-10s %-10s %10s %-s\n"; printf FMT, $1, GBYTES, $3, $4, $5, $6; next} {printf FMT,$1,$2/CNV,$3/CNV,$4/CNV,$5,$6}'`
export X;

In a new session for server as follows I got value.
Code:
echo $X
Filesystem GBytes Used Available Use% Mounted tmpfs 0.5 0.000367655 0.493422 1% /tmp

EDIT: You could use $ also for the command to put it into the alias name as follows.
Code:
X=$(df -k /tmp | awk 'NR==1 {CNV=1024*1024;GBYTES="GBytes";FMT="%-35s %-10s %-10s %-10s %10s %-s\n"; printf FMT, $1, GBYTES, $3, $4, $5, $6; next} {printf FMT,$1,$2/CNV,$3/CNV,$4/CNV,$5,$6}')
export X;

Thanks,
R. Singh

overview.fmt

OVERVIEW.FMT(5) 						File Formats Manual						   OVERVIEW.FMT(5)

NAME

       overview.fmt - format of news overview database

DESCRIPTION

       The file <pathetc in inn.conf>/overview.fmt specifies the organization of the news overview database.  Blank lines and lines beginning with
       a number sign (``#'') are ignored.  The order of lines in this file is important; it determines the order in which the fields  will  appear
       in the database.

       Most  lines  will  consist  of  an article header name, optionally followed by a colon.	A trailing set of lines can have the word ``full''
       appear after the colon; this indicates that the header should appear as well as its value.

       If this file is changed, new overview records will be constructed with the modified format.  If it is desired to update	existing  records,
       it is necessary to rebuild the existing overview database using makehistory(8) after removing all existing overview files.

       ``Xref:full'' must be included, or innd(8) and other programs which utilize overview method cannot start.

       The default file, show below, is compatible with Geoff Collyer's ``nov'' package:
	      Subject:
	      From:
	      Date:
	      Message-ID:
	      References:
	      Bytes:
	      Lines:
	      Xref:full

       Usually the only modifications which should be made to the default file are additions of new fields to the end of the file; all such fields
       should have ``full'' after the colon.  The first eight fields should remain in the same order as above.

HISTORY

       Written by Rich $alz <rsalz@uunet.uu.net> for InterNetNews.  Intended to be compatible with  the  nov  package  written	by  Geoff  Collyer
       <geoff@world.std.com>.  This is revision 1.6.6.3, dated 2002/01/05.
