# Description: Pick files and pipe the line-separated list to another utility
#
# Shell: bash
# Author: Arun Prakash Jana
#
# Usage:
# Copy this file in your $PATH, make it executable and preferably name it to picker.
# Run commands like:
# ls -l `picker`
# cd `picker`
# or, in fish shell:
# ls -l (picker)
# cd (picker)
#
# NOTE: This use case is limited to picking files, other functionality may not work as expected.
