   vi ~/.bashrc
   
   PATH=$PATH:$HOME/bin 加上你的路径 ， PATH=$PATH:$HOME/bin:/opt/mplayer/bin
   
   需要logout 再 login ，
   
   env | grep mplayer 查看有没有你的路径

   照楼的朋友方法可以了。export PATH=$PATH:/opt/mplayer/bin
   但不知在bashrc这个用户主目录里面哪里加，谢谢！

   在export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE INPUTRC
   的前面加上
   PATH=$PATH:/opt/mplayer/bin

   看到过LINUXredhat 9 书是介绍是用这个命令 env PATH=&PATH:/opt/mplayer/bin
   fedora中应该不行的。
   还有修改profile文件：.bashrc文件
   请问在里面什么地方修改，上面，下面，中间。
   
   # /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 [ "$2" = "after" ] ; then
   PATH=$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
   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

   好也

9. adminchen 于 2009-06-10 09:09:33发表:

   自己已经解决了。
   export PATH=$PATH:/opt/mplayer/bin

10. linsi 于 2009-06-10 09:06:12发表:

    改变 PATH 后要将它 export 到环境变量中以供其它地方调用：
    [root@localhost ~]# export PATH=$PATH:/opt/mplayer/bin
