有点难度的问题，超强系统错误

ChinaID

RHEL AS4, su到root，打入某个命令，如reboot，系统回答说bash: reboot: command not found，只好转到/usr/sbin目录下，再./reboot才可以正常执行。希望各位达人指教，已经搜遍google与baidu，无解。

下面是/etc/profile的内容：

# /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 "(^| $1($| " ; then
           if [ "$2" = "after" ] ; then
              PATH=$PATH1
           else
              PATH=$1PATH
           fi
        fi
}

# Path manipulation
if [ `id -u` = 0 ]; then
        pathmunge /sbin
        pathmunge /usr/sbin
        pathmunge /usr/local/sbin
fi

pathmunge /usr/X11R6/bin after


# No core files by default
ulimit -S -c 0 > /dev/null 2>&1

USER="`id -un`"
LOGNAME=$USER
MAIL="/var/spool/mail/$USER"

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

下面是~/.bashrc的内容:

# .bashrc

# User specific aliases and functions

alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'


# Source global definitions
if [ -f /etc/bashrc ]; then
        . /etc/bashrc
fi

谢谢楼上的达人。原来要在su -而不是su --，因为经常在BSD下做事，今天居然把LINUX的忘记了
