#!/usr/bin/env sh

# Description: Fuzzy find executables in $PATH and launch an application.
#              stdin, stdout, stderr are suppressed so CLI utilities exit silently.
#              Works as an independent app launcher.
#
#              Requires fzy.
#
#              Usage: nlaunch [delay]
#                     delay is in seconds, if omitted nlaunch waits for 1 sec
#
# Shell: POSIX compliant
