Full Discussion: unabel to ssh from script.
Top Forums UNIX for Advanced & Expert Users unabel to ssh from script. Post 302244729 by jsw371 on Wednesday 8th of October 2008 01:31:03 PM

If I change my shell script from:
$ cat ssh_test.ksh
#!/bin/ksh
ssh -v -v -v remote_server << EOT
date
EOT
if [ $? -ne 0 ]
then
echo failed
exit 1
fi
exit 0


to:

$ cat ssh_test.ksh
#!/bin/ksh
ssh -v -v -v remote_server date
if [ $? -ne 0 ]
then
echo failed
exit 1
fi
exit 0

it works. I was hoping to be able to use the <<EOT....EOT syntax because I want to expand this script to be able to use if statements and several commands. I was hoping not to have to put a script on each remote server. Over 100 remote servers I need to connect to.

Is there something obvious that I am missing?
