# Detection based on filename is rather complicated as there are many
# different file extensions and special filenames in use.
# This expressions aims to capture them all while not matching
# filenames that coincidentally contain the same substring.
#
# File extensions:
# * .sh
# * .bash
# * .ash
# * .ebuild (Gentoo ebuild format)
#
# Special filenames:
# * .bashrc, .bash_aliases, .bash_functions .bash_profile
# * profile, .profile (/etc/profile or ~/.profile)
# * Pkgfile
# * pkgmk.conf
# * rc.conf
# * PKGBUILD (Arch Linux build scripts)
# * APKBUILD
#
# Fix command (fc) files:
# * bash-fc. (followed by a random string)
