I am trying to figure out a way to ssh to remote server and check if file exists, and if it doesn't I want to leave the script with an exit status of 5.
I have the following that I am attempting to use, but it is not returning anything:
I know that the
Quote:
ssh $SOURCE_SERV "ls -l $SOURCE_LOC/$FILENAME"
works, as when I do this manually, the results are returned to the screen.
Does anyone have any suggestions or am I just going about this in completely the wrong way? We are running AIX 5.3 if that matters.

ssh-agent
ssh-agent(1) User Commands ssh-agent(1)NAME
ssh-agent - authentication agent
SYNOPSIS
ssh-agent [-a bind_address] [-c | -s ] [-d]
[command [args]...]
ssh-agent [-c | -s] -k
DESCRIPTION
ssh-agent is a program to hold private keys used for public key authentication (RSA, DSA). ssh-agent is often started at the beginning of a
login session. All other windows or programs are started as clients to the ssh-agent program. Through use of environment variables, the
agent can be located and automatically used for authentication when logging in to other machines using ssh(1). See the System Administra-
tion Guide: Security Services.
If a command line is given, this is executed as a subprocess of the agent. When the command dies, so does the agent.
The agent initially does not have any private keys. Keys are added using ssh-add(1), which sends the identity to the agent. Several identi-
ties can be stored in the agent; the agent can automatically use any of these identities. Use the -l option in ssh-add(1) to display the
identities currently held by the agent.
The agent is run in the user's local host. Authentication data need not be stored on any other machine, and authentication passphrases
never go over the network. However, if the connection to the agent is forwarded over SSH remote logins, the user can use the privileges
given by the identities anywhere in the network in a secure way.
There are two main ways to get an agent setup. Either you let the agent start a new subcommand into which some environment variables are
exported, or you let the agent print the needed shell commands (either sh(1) or csh(1) syntax can be generated) which can be evalled in the
calling shell. Later, use ssh(1) to look at these variables and use them to establish a connection to the agent.
A unix-domain socket is created (/tmp/ssh-XXXXXXXX/agent.pid) and the name of this socket is stored in the SSH_AUTH_SOCK environment vari-
able. The socket is made accessible only to the current user. This method is easily abused by root or another instance of the same user.
The SSH_AGENT_PID environment variable holds the agent's PID.
The agent exits automatically when the command given on the command line terminates.
OPTIONS
The following options are supported:
-a bind_address Binds the agent to the unix-domain socket bind_address. The default is /tmp/ssh-XXXXXXXX/agent.pid.
-c Generates C-shell commands on stdout. This is the default if SHELL indicates that it is a csh style of shell.
-d Debug mode. When this option is specified, ssh-agent will not fork.
-k Kills the current agent (given by the SSH_AGENT_PID environment variable).
-s Generates Bourne shell commands on stdout. This is the default if SHELL does not indicate that it is a csh style of
shell.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
1 An error occurred.
FILES
/tmp/ssh-XXXXXXXX/agent.pid
Unix-domain sockets used to contain the connection to the authentication agent. These sockets should only be readable by the owner. The
sockets are removed when the agent exits.
