# This file is immediately parsed and sourced by GDM's login manager upon GUI login.
# When login is through an interactive login shell, it is parsed after `/etc/profile`,
# provided the files `~/.bash_profile`, `.bash_login` do NOT exist.
#
# Our PATH segments are defined here, because `~/.bash_profile` actually sources this
# `~/.profile`.  This is recommended because when defining environmental variables only
# in `~/.bash_profile` only the `bash` shell has access to them.

# PATH
# #########
# Notes of caution:
# Do not add path segments in front of PATH as the order of priority for sourcing
# executable files in PATH is from left to right.  Misplacing new PATH segments at
# the beginning of PATH would radically modify the picking order when looking for
# executable files.
# This is also meant as a good practice as an attacker could potentially replace
# an innocuous looking cmd by something else in front of the PATH env var.
# Use $HOME/ instead of ~/ in PATH for portability
