Comparing multiple variables
Hi!

I've come up with a ksh-script that produces one or more lists of hosts.
At the and of the script, I would like to print only those hosts that exists in all the lists.

Ex.
HOSTS[1]="host1 host2 host3 host11"
HOSTS[2]="host1 host2 host4"
HOSTS[3]="host2 host11"
HOSTS[4]="host2 host5 host6 host7 host8"

This should generate a print-out of "host2" only.
How can I do this in a effective manner?

My current solution is not exact, so it would render a output of "host1 host2" as "host1" is part of string "host11".
($run contains the number of host-rows that are produced earlier)


for candidate in ${HOSTS[1]};do
HIT=true
for (( i=1;i<=$run;i++ ));do
if [ $(($i+1)) -le $run ];then
if ! [[ ${HOSTS[$i+1]} = *"$candidate"* ]];then
HIT=false
fi
fi
done
if [ x${HIT} = xtrue ];then
FINAL="$FINAL $candidate "
fi
done


Any ideas how to solve this?

ruptime

ruptime(1)						      General Commands Manual							ruptime(1)

NAME

       ruptime - Displays the status of each host on a network

SYNOPSIS

       ruptime [-ar] [-l  | -t	| -u]

       ruptime [-ar] [-l  | -t	| -u] [machinename]

       The ruptime command displays the status of each host on a local network that is running the rwhod daemon.

       If machinename is specified, only the status of that machine is displayed.

OPTIONS

       Includes all users.  Without this option, users whose sessions are idle an hour or more are not included.  Sorts the list by the load aver-
       age over 5-, 10-, and 15-minute intervals prior to a server's transmission.  The load averages are multiplied by 10 to represent the  value
       in decimal format.  Reverses the sort order.  Sorts the list by the length of uptime.  Sorts the list by the number of users.

DESCRIPTION

       The  status lines are sorted by hostname unless the -l, -t, or -u option is indicated. The status information is provided in packets broad-
       cast once every 3 minutes by each network host running rwhod. Any activity (such as the power to a host being turned on or off) that  takes
       place  between  broadcasts  is not reflected until the next broadcast. Hosts for which no status information is received for 11 minutes are
       reported as down.

EXAMPLES

       To get a status report on the hosts on the local network, enter: $ ruptime

	      Information  similar  to	the  following	 is   displayed:   host1     up   5:15, 	 4   users,    load   0.09,   0.04,   0.04
	      host2	up   7:45,	    3  users,	load  0.08,  0.07,  0.04  host3     up	 2:28,		0  users,   load  0.01, 0.02, 0.03
	      host4	up   3+01:44,  1 user,	 load 0.01, 0.02, 0.03 host7	 up   7:43,	     1 user,   load 0.06, 0.12, 0.11

	      (Output may be formatted differently on your system.)  To get a status report sorted by load average, enter: $ ruptime -l

	      Information  similar  to	the  following	 is   displayed:   host2     up   7:45, 	 3   users,    load   0.08,   0.07,   0.04
	      host1	up   5:18,	    4  users,	load  0.07,  0.07,  0.04  host7     up	 7:43,		1  user,    load  0.06, 0.12, 0.11
	      host3	up   2:28,	    0 users,  load 0.01, 0.02, 0.03 host4     up   3+01:44,  1 user,   load 0.01, 0.02, 0.03

	      (Output may be formatted differently on your system.)
