Bash device to allow selecting files for file management in a more interactive way
# Interactive File Management Utilities by hibi
#
# This source file will let you select individual files and copy and move them
# around much like a graphical file manager would. Intended to be used with
# `source` in your bashrc.
#
# Usage:
# Fsel name1 [name2 [...]] - selects files and folders
# Funsel [name1 [name2 [...]]] - unselects files and folders, or all
# Fcp [destination] - copies the files here or to destination
# Fmv [destination] - moves the files here or to destination
# Flsel - lists the current selection
#
# NOTE: This file was made for bash. It is untested in other shells.
# File Select
#
# Selects files by one or more paths or globs, and store their paths into a
# temporary buffer (`_FMG_PATH_BUF`). The previous selection is not cleared, so
# you can select files from different directories. See `Funsel` to clear the
# selection.
function Fsel() {

# just the filename (or basename), or a glob. If no arguments are provided, then
