我在.bashrc文件中添加了Hcatalog的导出语句，最终搞砸了我的.basrc文件。现在即使我在我的cmd中打开bashrc文件并删除这两个导出语句，我仍然无法运行任何命令。
我当前的bashrc文件：

我遇到的错误是：
hadoop namenode -format
hadoop:command not found
有谁可以帮我解决这个问题。 TIA。

有很多错误。一半的陈述，一些评论一些刚刚消失。出口已经转移到了生产线的末端。
我认为你应该重置文件：cp -f /etc/skel/.bashrc ~/

编辑您的bashrc文件，删除＆＃34;之后的所有内容＃sources /etc/bash.bashrc)."并添加以下行。
if [ -f /etc/bash_completion ] && ! shopt -oq posix; then
. /etc/bash_completion fi
export JAVA_HOME=/usr/lib/jvm/java-6-openjdk-amd64
export HADOOP_PREFIX=/home/itelligence/hadoop-1.2.0

发布此重启你的bashrc文件
source .bashrc
如果问题仍然存在
在终端中键入以下内容，
/bin/cp /etc/skel/.bashrc ~/
它将用新的替换你腐败的〜/ .bashrc。之后你需要提供〜/ .bashrc，以便立即进行更改，写入终端，
source ~/.bashrc
