如果你在~/中加入blah="/usr/bin/blah"。Bashrc，然后您可以在登录shell中使用$blah作为输入/usr/bin/blah的替代

在OS X上，你需要使用~/.bash_profile。这是因为默认终端。应用程序为每个新窗口打开一个登录shell。

查看更多关于不同的配置文件以及何时使用它们的信息: .bashrc， .bash_profile和.environment之间有什么区别?

和在OSX这里:关于.bash_profile， .bashrc，别名应该写在哪里?

要创建永久别名快捷方式，请将其放在.bash_profile文件中，并将.bashrc文件指向.bash_profile文件。遵循以下步骤(我正在创建一个名为bnode的别名命令来在ES6代码上运行babel transpiler):

Go to terminal command prompt and type “cd” (this will take you to the home directory. Note: even though your programming files may be located on your “D: drive”, your “.bash” files may be located on your “C: drive” ) To see the location of the home directory, type “pwd” (this will show you the home directory path and where the .bash files are probably located) To see all dot "." files in the home directory, type “ls -la” (this will show ALL files including hidden dot "." files) You will see 2 files: “.bash_profile” and “.bashrc” Open .bashrc file in VS Code Editor or your IDE and enter “source ~/.bash_profile” in first line (to point .bashrc file to .bash_profile) Open .bash_profile file in VS Code Editor and enter “alias bnode='./node_modules/.bin/babel-node'” (to create permanent bnode shortcut to execute as bash command) Save and close both files Now open the file you want to execute (index.js) and open in terminal command prompt and run file by using command “bnode index.js” Now your index.js file will execute but before creating bnode alias in .bash_profile file you would get the error "bash: bnode command not found" and it would not recognize and give errors on some ES6 code.

我希望这能有所帮助!好运！

您可以在启动脚本文件中添加别名或函数。通常是主目录下的.bashrc、.bash_login或.profile文件。

由于这些文件是隐藏的，您必须执行ls -a命令来列出它们。如果你没有，你可以创建一个。

如果我没记错的话，当我买了我的Mac时，.bash_login文件并不在那里。我必须为自己创建它，这样我就可以把提示信息、别名、函数等放在里面。

如果你想创建一个，以下是步骤:

启动终端 输入cd ~/进入主文件夹 输入touch .bash_profile创建新文件。 使用您喜欢的编辑器编辑.bash_profile(或者您可以键入open -e .bash_profile在TextEdit中打开它。 输入. .bash_profile重新加载.bash_profile并更新您添加的任何别名。

回家吧 打开. bashrc 在文件底部创建别名 别名alias_name='要做的命令' 例如:alias cdDesktop='cd /Desktop' 保存文件 源. bashrc 源~ / . bashrc 打开终端(Ctrl+Alt+T)，输入cdDesktop并按enter

macOS Catalina用户:

步骤1:创建或更新.zshrc文件

vi ~/.zshrc

步骤2:添加别名行

alias blah="/usr/bin/blah"

步骤3:源.zshrc

source ~/.zshrc 

步骤4:通过在命令提示符上输入alias来检查您的别名

alias
