Top Forums Shell Programming and Scripting Unable to ssh and list files in local directory from remote. Post 303024017 by rbatte1 on Thursday 27th of September 2018 03:57:20 AM

If you want to write to a local file from an SSH session, you would need to pass that to STDOUT within the SSH and then redirect the output of the whole SSH to a file on your local machine, something like this:-
Code:
ssh user@server "ls /path/to/files" > /tmp/file_list

If you have multiple statements to execute, you would need to do something more like this:-
Code:
ssh user@server "ls /path/to/files
date
uname -a" > /tmp/file_list

Given that you have this in a function, you could also remove any redirection form the function and then call it capturing all the output from the function call:-
Code:
ssh user@server "ls /path/to/files" > /tmp/file_list

Do any of these options help? If you really need a good chunk of remote processing to return some sort of filtered output and there may be other output you don't want, then you might have to write a file on the remote server and then copy it back to your local machine in a separate step to interrogate it. If you have SSH keys all in place, it shouldn't be too hard.



I hope that these help.
Let me know if I've completely missed the point.

SSH-COPY-ID(1)						    BSD General Commands Manual 					    SSH-COPY-ID(1)

NAME
ssh-copy-id -- copy public keys to a remote host SYNOPSIS
ssh-copy-id [-lv] [-i keyfile] [-o option] [-p port] [user@]hostname DESCRIPTION
The ssh-copy-id utility copies public keys to a remote host's ~/.ssh/authorized_keys file (creating the file and directory, if required). The following options are available: -i file Copy the public key contained in file. This option can be specified multiple times and can be combined with the -l option. If a private key is specified and a public key is found then the public key will be used. -l Copy the keys currently held by ssh-agent(1). This is the default if the -i option was not specified. -o ssh-option Pass this option directly to ssh(1). This option can be specified multiple times. -p port Connect to the specified port on the remote host instead of the default. -v Pass -v to ssh(1). The remaining arguments are a list of remote hosts to connect to, each one optionally qualified by a user name. EXIT STATUS
The ssh-copy-id utility exits 0 on success, and >0 if an error occurs. EXAMPLES
To send a specific key to multiple hosts: $ ssh-copy-id -i /path/to/keyfile.pub user@host1 user@host2 user@host3 HISTORY
The ssh-copy-id utility was written by Eitan Adler <eadler@FreeBSD.org> as a drop-in replacement for an existing utility included with OpenSSH. BSD
