/etc/profile设置的都是全局环境变量吗

tuza

为什么我在/etc/profile里设置的变量只能有一个用户好使，其它用户甚至root都用不了？
下面是我的profile:
# /etc/profile -*- Mode: shell-script -*-
# (c) MandrakeSoft, Chmouel Boudjnah <chmouel@mandrakesoft.com>

#set postgresql
POSTGRES_HOME=/usr/local/pgsql
PATH=$PATHPOSTGRES_HOME/bin

#Set java
JAVA_HOME=/usr/java/j2sdk1.4.1_01
PATH=$PATHJAVA_HOME/jre/bin
PATH=$PATHJAVA_HOME/bin

loginsh=1

# Users generally won't see annoyng core files
[ "$UID" = "0" ] && ulimit -S -c 1000000 > /dev/null 2>&1

if ! echo ${PATH} |grep -q /usr/X11R6/bin ; then
    PATH="$PATH:/usr/X11R6/bin"
fi

if [ "$UID" -ge 500 ] && ! echo ${PATH} |grep -q /usr/games ; then
    export PATH=$PATH:/usr/games
fi

umask 022

USER=`id -un`
LOGNAME=$USER
MAIL="/var/spool/mail/$USER"
HISTCONTROL=ignoredups
HOSTNAME=`/bin/hostname`
HISTSIZE=1000

if [ -z "$INPUTRC" -a ! -f "$HOME/.inputrc" ]; then
    INPUTRC=/etc/inputrc
fi

# some old programs still use it (eg: "man"), and it is also
# required for level1 compliance for LI18NUX2000
NLSPATH=/usr/share/locale/%l/%N

export PATH PS1 USER LOGNAME MAIL HOSTNAME INPUTRC NLSPATH
export HISTCONTROL HISTSIZE
export POSTGRES_HOME
export JAVA_HOME

for i in /etc/profile.d/*.sh ; do
        if [ -x $i ]; then
                . $i
        fi
done

unset i
