求助：ubuntu路径问题

[jim166783]

sudo gedit ~/.bashrc

在最后一行 添加
export PATH=/usr/local/arm/3.4.1/bin

我使用如上命令设置环境变量后，使用sudo dir等命令都不行了

Command 'sudo' is available in '/usr/bin/sudo'
The command could not be located because '/usr/bin' is not included in the PATH environment variable.
bash: sudo：找不到命令

Command 'dir' is available in '/bin/dir'
The command could not be located because '/bin' is not included in the PATH environment variable.
bash: dir：找不到命令

好像“export PATH=/usr/local/arm/3.4.1/bin”把原来的路径给覆盖掉了

请问如何加上“export PATH=/usr/local/arm/3.4.1/bin”而不影响sudo dir等功能呢

在原来的PATH后面加上下面一行

代码： 全选

export PATH=$PATH:/usr/local/arm/3.4.1/bin

不覆盖过去的

或者干脆直接把你想添加的路径填入原来的PATH后面

用这代码:
export PATH=$PATH:/usr/local/arm/3.4.1/bin

可以用了，非常感谢 greatgarlic
