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
