I can't quite follow this request, nor do I understand its relation to the title "Ssh newbie", but if you have a file name stub in a variable that, in real filenames, is followed by two digits, which in turn you want incremented, try
Code:
$ HN=$(ls $stub[0-9][0-9] | tail -1)
$ printf -vFN "$stub%02d" $((${HN##*[^0-9]} + 1))

$FN now has the filename with the number incremented by one.

NAME
knife-ssh - Run a command or interactive session on multiple remote hosts SYNOPSIS
knife ssh QUERY COMMAND (options) -a, --attribute ATTR The attribute to use for opening the connection - default is fqdn -C, --concurrency NUM The number of concurrent connections -m, --manual-list QUERY is a space separated list of servers -P, --ssh-password PASSWORD The ssh password -x, --ssh-user USERNAME The ssh username -i, --identity-file IDENTITY_FILE The SSH identity file used for authentication -p, --ssh-port PORT The ssh port --[no-]host-key-verify Verify host key, enabled by default. DESCRIPTION
The ssh sub-command opens an ssh session to each of the nodes in the search results of the QUERY. This sub-command requires that the net-ssh-multi and highline Ruby libraries are installed. On Debian systems, these are the libnet-ssh-multi-ruby and libhighline-ruby pack- ages. They can also be installed as RubyGems (net-ssh-multi and highline, respectively). TERMINAL MULTIPLEXING AND TERMINAL TAB SUPPORT
knife ssh integrates with several terminal multiplexer programs to provide a more convenient means of managing multiple ssh sessions. When the COMMAND option matches one of these, knife ssh will create multiple interactive ssh sessions running locally in the terminal multi- plexer instead of invoking the command on the remote host. The available multiplexers are: interactive A built-in multiplexer. interactive supports running commands on a subset of the connected hosts in parallel screen(1) Runs ssh interactively inside screen. ~/.screenrc will be sourced if it exists. tmux(1) Runs ssh interactively inside tmux. macterm (Mac OS X only) Opens a Terminal.app window and creates a tab for each ssh session. You must install the rb-appscript gem before you can use this option. SEE ALSO
