打开终端并运行Shell脚本（CentOS）后出现Bash错误 [英] Bash error after opening Terminal and running shell scripts (CentOS)

问题描述

每次我在CentOS 6.4中打开终端时，都会出现错误：

  bash：usr / local / bin：否这样的文件或目录
  

我检查了.bashrc和.bash_profile来查看是否有任何行参考usr / local / bin，但未找到任何内容。当我切换到root或运行shell脚本时，也会出现相同的错误。

就像在usr前面添加反斜线一样简单吗？像这样-

  / usr / local / bin 
  

虽然还是不知道错误发生在哪里。任何帮助深表感谢。谢谢！

解决方案

这很奇怪，因为centos 6.4系统上的普通bash目录是/ bin / bash，但是我建议您需要检查以下内容：

  echo $ SHELL 
  

它应该拉出您的SHELL环境变量，以向您显示您正在使用的Shell，通常看起来像这样：

SHELL = / bin / bash

如果不同，例如：

SHELL = usr / local / bin / bash

然后我将检查您的passwd文件，以确保您的用户默认shell指向正确的位置。

用户名：x：601：601 :: / home /用户名： / bin / bash

我也建议您检查您的位置外壳实际上生活了

 其中bash 
 / bin / bash 
   pre> 
 
 
并确保所有内容都指向正确的位置。 
 
Every time I open Terminal in CentOS 6.4, I get the error:
bash: usr/local/bin: No such file or directory
I've checked .bashrc and .bash_profile to see if there are any lines that reference usr/local/bin, but haven't found anything. The same error also appears when I switch to root, or run a shell script. 

Is it as simple as adding a backslash in front of usr? Like so--
/usr/local/bin
Still don't know where the error is happening though. Any help is much appreciated. Thanks!
解决方案
This is strange as the normal bash directory on a centos 6.4 system is /bin/bash, however I would advise you to check the following:
echo $SHELL
It should pull your SHELL environment variable to show you where what shell you are using, normally it looks like this:

SHELL=/bin/bash

If it's different say for example:

SHELL=usr/local/bin/bash

then I would check your passwd file to make sure your users default shell is pointing to the right place.

username:x:601:601::/home/username:/bin/bash

Also I would suggest check where you shell actually lives
which bash
/bin/bash
And make sure everything is pointing to the correct location.
