A little dmenu script I made to handle ssh connections

ssh-dmenu

#!/bin/bash

# get hostnames from ~/.ssh/known_hosts
ssh_host="$(awk -F "[ ,]+" '{print $1}'  ~/.ssh/known_hosts | tr -d '[]' | uniq | sort -n | dmenu)"
# split hostnames into array { hostname, port }
mapfile -t params < <(echo "$ssh_host" | awk -F ":" '{print $1} {if ($2) print $2}')

if [ -n "$ssh_host"  ]; then
    # If array size is two then second parameter is port number
    if [ ${#params[@]} -eq 2 ]; then
        $TERMINAL -e ssh "${params[0]}" -p "${params[1]}"
    else
        $TERMINAL -e ssh "${params[0]}"
    fi
fi
