Shell script to check whether directory exists on remote server

[sudhirav]

Hi All,

I am new to scripting, would like to have a script that tests whether a directory exists on remote host & display the message accordingly. The remote hostname can be provided by means of file containing list of hostnames. Can use rsh for connecting to remote host.

I tried with couple of scripts by searching google but didn't get desired result. Please help me, below is my efforts, $file contains list of hostnames.

for i in $file
do
if ( [ `rsh $i test -d /tmp/.X*` ] || [ `rsh $i test -d /scratch/.X*` ] )
then
echo "directory exist"
else
exit 0;
fi
done

Thanks in advance, appreciate all the efforts.

I would use ssh instead of rsh - rsh is unsecured and very old.

localhost#ssh user@remote "[ -d /tmp ]"
localhost#echo $?
localhost#ssh user@remote "[ -d /xyz ]"
localhost#echo $?

I agree ssh is more secure than rsh, would like to test the condition whether directory exists on remote server & also display message accordingly if it exists, the condition has to be run inside a loop as the number of hosts to be tested are many & hostnames are passed as $file in the script.

Thanks for the help.

Can you create passwordless ssh login ?

for i in {1..10};
do
ssh user@client$i "[ -d /xyz ]"
if [$? -eq 0]
then
echo "exists"
fi
done

Try "pdsh" thats more powerful than rsh or ssh.
