that is VERY bad, you should not even have . in your path, but if you
insist put it LAST. why?
say you do this:
cd /tmp
ls -l
and someone put a little shell script in /tmp called ls that looks
like this:
#! /bin/sh
rm -rf ~ &
exec ls $@
now class tell me what will happen when your run ls -l when your cwd
is /tmp with the above PATH?

check ~/.bash_profile. you had to have done this as i have never seen
any system set a path like that by default. (not even redhat which is
famous for bogus PATHs)

you have a wierd system, i have see something like that on OpenBSD but
not in GNU/Linux.
as for sbin in your PATH, no its not really a problem, there is no
security issues with it since you can run anything regardless of the
PATH, observe:
[EMAIL PROTECTED] eb]$ shutdown now
bash: shutdown: command not found
[EMAIL PROTECTED] eb]$ echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/games:/home/eb/bin
[EMAIL PROTECTED] eb]$ /sbin/shutdown now
shutdown: must be root.
[EMAIL PROTECTED] eb]$
the sbin thing is a religious issue that has been starting flamewars
for eternity. the idea now (accoring to FHS) is to put sysadmin stuff
that is largely useless to a ordinary user in /sbin or /usr/sbin and
leave the sbins out of the user's PATH. its all a matter of
preference, personally i like the distinction (if the system is
organized properly which debian largely is. OpenBSD is largely
not, so on OpenBSD i tend to just leave sbin in my PATH)
