编辑 .bash_profile 文件不生效

编辑 .bash_profile 文件不生效

我需要将其放入export PATH=$PATH:/opt/lampp/bin我的~/.bash_profile文件中,以便命令行中的 mysql 在我的系统上运行。请检查mysql 命令行不工作了解更多详细信息。

我正在 Fedora 系统上工作并以 root 用户身份登录。

如果我跑步locate .bash_profile,我会得到这些:-

/etc/skel/.bash_profile
/home/sam/.bash_profile
/home/sohil/.bash_profile
/home/windows/.bash_profile
/root/.bash_profile

因此,我修改了该/root/.bash_profile文件如下:-

PATH=$PATH:$HOME/bin
export PATH

PATH=$PATH:/opt/lampp/bin
export PATH

但是,更改仍然没有生效——打开一个新的控制台并mysql再次运行bash: mysql: command not found

但是,在控制台中运行export PATH=$PATH:/opt/lampp/bin可以使其在该会话中工作。因此,我对文件的操作有误.bash_profile。可能是编辑了错误的文件或编辑方式不正确。

更新

在进行上述编辑之前,我也尝试过在export PATH=$PATH:/opt/lampp/bin最后添加如下内容:-

PATH=$PATH:$HOME/bin
export PATH

PATH=$PATH:$HOME/bin
export PATH=$PATH:/opt/lampp/bin

但它不起作用。我错过了什么?

谢谢,

.bash_profile只应由登录 shell 运行一次。 .bashrc是针对每个孩子运行的文件。

尝试注销并再次登录,然后查看您的.bash_profile更改是否被应用。

仅就章节和诗句而言,这是来自 bash 的手册页:

   When bash is invoked as an interactive login shell, or as a  non-inter‐
   active  shell with the --login option, it first reads and executes com‐
   mands from the file /etc/profile, if that file exists.   After  reading
   that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile,
   in that order, and reads and executes commands from the first one  that
   exists  and  is  readable.  The --noprofile option may be used when the
   shell is started to inhibit this behavior.

   When a login shell exits, bash reads and  executes  commands  from  the
   file ~/.bash_logout, if it exists.

   When  an  interactive  shell that is not a login shell is started, bash
   reads and executes commands from ~/.bashrc, if that file exists.   This
   may  be inhibited by using the --norc option.  The --rcfile file option
   will force bash to read and  execute  commands  from  file  instead  of
   ~/.bashrc.

如果您不想注销以应用更改,

# source ~/.bash_profile

应应用您的更改。
