Running script commands after SSH

Question

I need to write a script that will SSH into a remote host, then run certain commands on that remote host, then exit. If I just do

ssh $host

#some command

the script will SSH in, wait until I manually exit, then run the commands.

How do I run those commands on the remote host?

You can also use fabric (fabfile.org)

ssh $host 'command1; command2; command3'

or if you have just one command:

ssh $host command1

or if you have many commands (a script file):

cat file | ssh $host sh

how would we modify the third option if there are arguments that need to be passed?

I want to run a command when ssh successfully and still keep the connection so that I can do the other task, but with this solution, the connection auto close

@TrungNguyen: you can do something like: ssh [email protected] -t 'cd /some/where; bash -l', but you can't do it directly

This can be used too, if you have multiple servers.

for ((i=1; i <= 10; i++))
do
echo $i
ssh host$i << EOF
cd /somedir
command1;
command2;
EOF
done
