向.bashrc添加了别名，但没有结果

Question

我在主目录中的.bashrc中添加了别名（alias homedir ='cd / export / home / file / myNmae'），然后重新启动了会话。 当我运行别名时，它说“ homedir：找不到命令”。

请指教。

Answer 1

这是因为.bashrc并非每次都源，仅适用于交互式非登录shell .bashrc。

从bash手册页。

When bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from  the  file  /etc/pro-
   file,  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 files ~/.bash_logout and /etc/bash.bash_logout, if the files 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.

我找到了解决方案-我将其添加到.profile文件中并重新启动了会话-
