Given an input.txt that represents a linked list a -> b -> c -> d -> e as a series of nodes with next pointers:

a>b
b>c
c>d
d>e

Reverse the linked list such that the output reads:

ben-ng

#!/usr/bin/env bash

# Where input.txt is:
# a>b
# b>c
# c>d
# d>e

paste -d '>' <(< input.txt | cut -d'>' -f2 | tac) <(< input.txt | cut -d'>' -f1 | tac)

ben-ng

#!/usr/bin/env bash
