I am trying to read from a file for the list of servers and then
instruct the script to login on these servers and run a command to
check one text file.

So far its done the below way...

cat server-list | \
while read line
do
echo "------------------------------------------------" >>test.out
echo " HOST : $line" >>test.out
echo "_____________________________________________ ___" >>test.out
rsh $line cat /home/basks.tbl|awk '{ print $1 }' >>test.out
done

The problem seems to be that script does not work !!! :-)

Any ideas around using cat wiht the while loop in a better way ?

why recreate what is already provided to you?

man dsh

>> man dsh
dsh is part of csm (or pssp if you still run it) and not everyone has
csm right ?

Depends what your error is ..

>> Any ideas around using cat wiht the while loop in a better way ?

for host in $(cat server-list)
do
rsh ${host} "awk '{print $1}' /home/basks.tbl" >> test.out
done

Any good to you ?

....
The dsh is provided from the csm.dsh package which is available since
AIX 5.3 ( Maybe even AIX 5.2 ) and i believe its even installed by
default.

But it will still need configuring even if the fileset is installed !

and do we even know what level of code the OP is running was my
point ...

But we still don't know what type or error you get.
So all I can do is guessing. Maybe
-n Specifies that the rsh command should not read from standard input.
is the option you are missing. The rsh line then will be
rsh $line -n cat /home/basks.tbl|awk '{ print $1 }' >>test.out

One thing that you should be aware of when using either dsh, or
rsh is where your variables are getting interpreted, and where your
commands are actually being run.

For example, In your original example:

rsh $line cat /home/basks.tbl|awk '{ print $1 }' >>test.out

The cat is done on the remote node, the awk is done on the local node.
The entire /home/basks.tbl is being sent across the network.

What Mark had suggested is better, in a way...

rsh ${host} "awk '{print $1}' /home/basks.tbl"

The awk runs on the remote node, but the "$1" gets interpreted by
the local shell, and is replaced with a blank. This would mean that
the
whole file would be returned.
(To check the interpretations, use set -x and try the command
individually)

This would work better:
rsh ${host} "awk '{print \$1}' /home/basks.tbl"

Not understanding where the commands are being executed, and how the
variables
are interpreted will cause confusion about your data returned, but it
won't cause
the rsh to fail.

So, as Thomas has hinted, more information about what is actually
failing will probably
give you more help on how to fix it.

Hope this Helps
