Combines the power of lastpass cli and fzf to offer an interactive fuzzy finding password experience on the command line. Lists all lastpass passwords and pipes into FZF to search by name. Once selected, the script copies desired password to the system clipboard.

lpass-tool.sh

#!/bin/bash

lpass_data=$(lpass ls)
if [[ "$lpass_data" == "" ]]; then
    echo 'Error: You are likely not logged into lastpass, attempting to login'
    exit 1
fi

chosen_element=$(echo "$lpass_data" | fzf)

if [[ "$!" -eq 0 ]]; then
    chosen_element_id=$(echo "$chosen_element" | egrep -o 'id: [0-9]+' | awk '{ print $2; }')
    echo "Chose id: $chosen_element_id"
    lpass show --password --clip "$chosen_element_id"
else
    echo 'Cancelled operation...'
fi

Made some tweaks

#!/bin/sh

if echo 'n' | lpass logout 2>&1 | grep -qv "you sure"; then
    echo 'Not logged in. Enter lastpass username:'
    read username
    lpass login "$username"
    if [ ! "$?" -eq 0 ]; then
      echo "Failed to login" >&2
      exit $?
    fi
fi

chosen_element="$(lpass ls | fzf)"

if [ "$?" -eq 0 ]; then
    chosen_element_id="$(echo "$chosen_element" | egrep -o 'id: [0-9]+' | awk '{ print $2; }')"
    echo "Chose id: $chosen_element_id"
    lpass show --password "$chosen_element_id" | xclip -selection clipboard
else
    echo 'Cancelled operation...'
fi
