新手求助..我的bash 的命令不能用了

baorui_ren

有朋友在我LINUX下安装一个软件不成功后好像留下了些问题
就是我在bash下用不了命令了. 而root的默认shell是bash,,我也无法用vi 之类的编辑命令更改ect/bashrc ..请大虾们帮帮忙...

寂寞烈火

$PATH的问题吧

请问是在哪个文件里更改呢?bashrc?我现在如果以root登录,,bash下就只能用它内带的命令,,我该用什么方法去编辑相应的文件呀??HELP

我的bashrc如下
# /etc/bashrc

# System wide functions and aliases
# Environment stuff goes in /etc/profile

# by default, we want this to get set.
# Even for non-interactive, non-login shells.
if [ "`id -gn`" = "`id -un`" -a `id -u` -gt 99 ]; then
umask 002
else
umask 022
fi

# are we an interactive shell?
if [ "$PS1" ]; then
   if [ -x /usr/bin/tput ]; then
     if [ "x`tput kbs`" != "x" ]; then # We can't do this with "dumb" terminal
       stty erase `tput kbs`
     elif [ -x /usr/bin/wc ]; then
       if [ "`tput kbs|wc -c `" -gt 0 ]; then # We can't do this with "dumb" terminal
         stty erase `tput kbs`
       fi
     fi
   fi
   case $TERM in
xterm*)
if [ -e /etc/sysconfig/bash-prompt-xterm ]; then
PROMPT_COMMAND=/etc/sysconfig/bash-prompt-xterm
