You will need to send the b.sh to the remote host and make it executable. Use sftp for this. You could add this to your script so if you have several servers, an update to b.sh gets copied out each time.

To get a log file back, again an sftp get would be appropriate.

The sftp should be quite straightforward if ssh is already set up as a password-less connection.

You will end up with something like this logic:-
  • Setup generate environment on local server
  • For each server in list:-
    • Send script with sftp setting the execute on
    • Use ssh to run script remotely and generate log file
    • Retrieve log file with sftp
    • Determine if b.sh needs to flag an error and take action
  • Loop with next server in list
As an alternate, you might also consider:-
  • Setup generate environment on local server
  • For each server in list:-
    • Send script with sftp setting the execute on
    • Use ssh to run script remotely and generate log file
    • Retrieve log file with sftp to a file-name based on the server
  • Loop with next server in list
  • Process all logs to report as appropriate

Do either of these give you something to build on?

NAME

       sftp-server - SFTP server subsystem

SYNOPSIS

       /usr/lib/ssh/sftp-server

DESCRIPTION

       sftp-server implements the server side of the SSH File Transfer Protocol as defined in the IETF draft-ietf-secsh-filexfer.

       sftp-server is a subsystem for sshd(1M) and must not be run directly. There are no options or config settings.

       To enable the sftp-server subsystem for sshd add the following to /etc/ssh/sshd_config:

       Subsystem   sftp     /usr/lib/ssh/sftp-server

       See sshd_config(4) for a description of the format and contents of that file.

       There is no relationship between the protocol used by sftp-server and the FTP protocol (RFC 959) provided by in.ftpd.

EXIT STATUS

       The following exit values are returned:

       0        Successful completion.

       >0       An error occurred.
