请教PATH设置问题

wang771

我在/etc/profile加了一行
PATH=$PATH:/usr/local/j2sdk1.4.2/bin:/usr/local/j2sdk1.4.2/jre/bin
重新登陆后没有生效，请指点，谢谢。详细设置如下：
[root@t800 root]# cat /etc/profile
# /etc/profile

# System wide environment and startup programs, for login setup
# Functions and aliases go in /etc/bashrc


# Path manipulation
if [ `id -u` = 0 ] && ! echo $PATH | /bin/grep -q "/sbin" ; then
    PATH=/sbinPATH
fi

if [ `id -u` = 0 ] && ! echo $PATH | /bin/grep -q "/usr/sbin" ; then
    PATH=/usr/sbinPATH
fi

if [ `id -u` = 0 ] && ! echo $PATH | /bin/grep -q "/usr/local/sbin" ; then
    PATH=/usr/local/sbinPATH
fi

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

PATH=$PATH:/usr/local/j2sdk1.4.2/bin:/usr/local/j2sdk1.4.2/jre/bin

export PATH=$PATH:/usr/local/j2sdk1.4.2/bin:/usr/local/j2sdk1.4.2/jre/bin

wang771

谢谢。单独运行export  PATH:/usr/local/j2sdk1.4.2/bin:/usr/local/j2sdk1.4.2/jre/bin可以，
但加在/etc/profile里还是不行

sakulagi

不会吧，把这句写道/etc/profile里没有作用？
