populate variable from remote result
Hi there

i am trying to pass the result of a remote command into a variable into my script

ie
Code:
#!/bin/sh

var = `ssh remote_box 'uname'`
echo $var

but all i get back is

Code:
./script.sh[3]: var:  not found


However when i add a -x to put it into diag mode i get the following

Code:
+ ssh remote_server uname
+ var = SunOS
./script[3]: var:  not found
+ echo

so it looks like the variable var is actually being populated but i cant echo it


does anybody know what im doing wrong here?

Cheers
Gary

LEARN ABOUT OPENSOLARIS

dtappsession

dtappsession(1) 						   User Commands						   dtappsession(1)

NAME

       dtappsession - start a new Application Manager session

SYNOPSIS

       /usr/dt/bin/dtappsession  [hostname]

DESCRIPTION

       dtappsession  is  a specialized version of the Xsession shell script. It is an alternative to using the CDE remote login that allows you to
       access a remote host without logging out of your current CDE session. dtappsession starts a new instance of the CDE Application Manager	in
       its  own  ToolTalkTM  session.  It can be used to remotely display the Application Manager back to your local display after logging in to a
       remote host with the rlogin(1) command.

       A new, independent instance of ttsession(1) starts a simple session management window. This window displays the title

	 remote_hostname: Remote Administration

       where remote_hostname is the system that is being accessed. The window also displays an Exit button. Clicking Exit terminates the  ToolTalk
       session and all windows that are part of the session.

       The  Application  Manager that is displayed can be used to start remote CDE actions to run in this session. Exiting the Application Manager
       does not terminate the session, and it is not recommended. Clicking Exit is the recommended way to end the session. To avoid confusing  the
       remote CDE applications with local ones, it is recommended that a new CDE workspace be created for clients in the remote session.

       The hostname is not needed when the DISPLAY environment variable is set to the local hostname on the remote host.

       On  a  system  that  is configured with Trusted Extensions, dtappsession can be used for remote administration by administrative roles that
       have the ability to log in to the remote host.

       dtappsession does not require any privilege, and it does not need to run on a system that  is  configured  with	Trusted  Extensions.  When
       installed  in  /usr/dt/bin  on a Solaris system, along with the startApp.ds file, dtappsession can be used to administer the remote Solaris
       system from a local system that is configured with Trusted Extensions. However, in this case, the CDE workspace that  is  used  for  remote
       display must be a normal workspace, rather than a role workspace.

EXAMPLES

       Example 1 Remote Login and dtappsession

       After creating a new CDE workspace, type the following in a terminal window:

	 # rlogin remote_hostname
	 password: /*type the remote password*/

	 # dtappsession local_hostname /* on the remote host */

FILES

       /usr/dt/bin/startApp.ds	  dt Korn shell script for session manager window

       +-----------------------------+-----------------------------+

BUGS

       X11/CDE	applications  that  do	not register with the ToolTalk session manager will not exit automatically when the session is terminated.
       Such applications must be explicitly terminated.
