If you have an SSH config file, and don't want to remember all the entries (in my case, with home and work, my list is about 50 entries)

#!/bin/bash

typeset -i looper=0
typeset -A hostArray

while read comment hostName
do
    is_break=`echo $comment | cut -c 1-2`
    if [ ${is_break} == "#_" ]; then
       echo "-----------------------------------------------------------"
    else
       looper=$looper+1
       hostArray[$looper]=$hostName
       echo "${looper}) $hostName"
    fi
done <<< $(cat ~mlivolsi/.ssh/config | egrep 'Host|#_' | grep -v 'HostName' | grep -v 'StrictHostKeyChecking' | grep -v 'UserKnownHostsFile' | grep -v 'HostKeyAlgorithms' )

echo -e "===> \c"
