quick SSH using peco, remembers past connections, presents a filterable list. relies on SSH keys for auth.

bash.sh

sss() {

    cat ~/.connections | sort | uniq > ~/.connections_ && mv ~/.connections_ ~/.connections

    IFS=$'\n' array=($(cat ~/.connections | cut -d" " -f1 | peco --print-query))

    r1=${array[1]}
    r2=${array[2]}

    addr=""

    if [[ "$r2" == "" ]]; then

        #echo No match, using $r1
        addr=$r1

    else

        # echo match, using $r2
        addr=$r2
    fi

    user=$(cat ~/.connections | grep $addr | cut -d" " -f2)

    if [[ "$user" == "" ]]; then

        echo Enter user
        read user
    fi

    ssh -o PreferredAuthentications=publickey $user@$addr

    if [[ $? == 0 ]]; then

        echo $addr $user >> ~/.connections

    else

        echo Failed, try installing public key

        ssh-copy-id $user@$addr

        ssh -o PreferredAuthentications=publickey $user@$addr

        if [[ $? == 0 ]]; then

            echo $addr $user >> ~/.connections
        fi
