PATH variable set incorrectly?

I've noted that in order to use commands like ifconfig, I have to prefix the commands with the directory.

/etc/profile shows that the paths should be part of the PATH environment variable; any idea where the bug is?

# /etc/profile
# System wide environment and startup programs, for login setup
# Functions and aliases go in /etc/bashrc
pathmunge () {
if ! echo $PATH | /bin/egrep -q "(^|Smilie$1($|Smilie" ; then
if [ "$2" = "after" ] ; then
PATH=$PATH:$1
else
PATH=$1:$PATH
fi
fi
}
# ksh workaround
if [ -z "$EUID" -a -x /usr/bin/id ]; then
EUID=`id -u`
UID=`id -ru`
fi
# Path manipulation
if [ "$EUID" = "0" ]; then //what does this mean?
pathmunge /sbin
pathmunge /usr/sbin
pathmunge /usr/local/sbin
fi
# No core files by default
ulimit -S -c 0 > /dev/null 2>&1
if [ -x /usr/bin/id ]; then
USER="`id -un`"
LOGNAME=$USER
MAIL="/var/spool/mail/$USER"
fi
HOSTNAME=`/bin/hostname`
HISTSIZE=1000
if [ -z "$INPUTRC" -a ! -f "$HOME/.inputrc" ]; then
INPUTRC=/etc/inputrc
fi
export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE INPUTRC
for i in /etc/profile.d/*.sh ; do
if [ -r "$i" ]; then
. $i
fi
done
unset i
unset pathmunge
------------------


echo $PATH
/usr/kerberos/sbin:/usr/java/jdk1.5.0_16/bin:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/home/sinfo/bin

does not include /sbin

EUID in this script evaluates to the effective user id. Whem you sudo your change your effective id, for example.

What is in the .bashrc file or .profile file in your home directory.

You also need to check the files in this loop
Code:
for i in /etc/profile.d/*.sh ; do
if [ -r "$i" ]; then
. $i
fi

ls -l /etc/profile.d/*.sh will show you what files are executed Look for files you can read/execute.
