Look in your ~/.bashrc and, if you've not changed anything, you'll see....
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
And then look in /etc/bashrc and you'll see....
if ! shopt -q login_shell ; then # We're not a login shell
# Need to redefine pathmunge, it get's undefined at the end of /etc/profile
pathmunge () {
case ":${PATH}:" in
*:"$1":*)
;;
*)
if [ "$2" = "after" ] ; then
PATH=$PATH:$1
else
PATH=$1:$PATH
fi
esac
}
So, it depends on if your shell is a login shell or not.
Also, other bits in $PATH are set via scripts in /etc/profile.d/ .
