Look in /etc/profile for the last 'PATH=' entry; after that add
Code:
PATH="${PATH}:/usr/local/firefox"
log out, log back in (/etc/profile is only read once at login) and you'll be good to go.
The section you're looking for is somewhere after something that will look like this:
Code:
# Set the default system $PATH:
PATH="/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/usr/games"
# For root users, ensure that /usr/local/sbin, /usr/sbin, and /sbin are in
# the $PATH. Some means of connection don't add these by default (sshd comes
# to mind).
if [ "`id -u`" = "0" ]; then
echo $PATH | grep /usr/local/sbin 1> /dev/null 2> /dev/null
if [ ! $? = 0 ]; then
PATH=/usr/local/sbin:/usr/sbin:/sbin:$PATH
fi
fi
# Set the additional $PATH:
PATH="${PATH}:/usr/local/seamonkey"
PATH="${PATH}:/usr/local/firefox"
PATH="${PATH}:/usr/local/thunderbird"
