Remote command in variable using ssh
Hi, I've an issue in a shell script:

I'm opening an ssh connection to a remote server, then I want to store the result of a ls command in a variable, but it doesn't work: the ls is done on the local machine.
Code:
ssh user@server << EOF
 ls # works as expected (ls is done remotely)
 test=`ls` # the ls is done locally and not remotely
EOF

Note: I have to use EOF, because they are several others commands done during the ssh.

any solution for this problem ?

ssh-argv0

SSH-ARGV0(1)                                                BSD General Commands Manual                                               SSH-ARGV0(1)

NAME

     ssh-argv0 -- replaces the old ssh command-name as hostname handling

SYNOPSIS

     hostname | user@hostname [-l login_name] [command]

     hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name]
     [-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command]

DESCRIPTION

     ssh-argv0 replaces the old ssh command-name as hostname handling.  If you link to this script with a hostname then executing the link is
     equivalent to having executed ssh with that hostname as an argument.  All other arguments are passed to ssh and will be processed normally.

OPTIONS

     See ssh(1).

FILES

     See ssh(1).
