在我的.bashrc文件中，默认存在以下行:

# Alias definitions.
# You may want to put all your additions into a separate file like
# ~/.bash_aliases, instead of adding them here directly.
# See /usr/share/doc/bash-doc/examples in the bash-doc package.

if [ -f ~/.bash_aliases ]; then
    . ~/.bash_aliases
fi

因此，在我的平台中.bash_aliases是默认情况下用于别名的文件(也是我使用的文件)。我不是OS X用户，但我猜如果你打开你的.bashrc文件，你就能识别出平台中常用的别名文件是什么。

苹果将默认shell转换为zsh，因此配置文件包含~/。Zshenv和~/.zshrc。这就像~/。Bashrc，但zsh。只需编辑文件并添加您需要的内容;每次打开一个新的终端窗口时，都应该引用它:

纳米~ - zshenv。 别名py = python)

然后按ctrl+x, y，然后输入保存。

该文件似乎无论在什么情况下(登录、非登录或脚本)都要执行，因此似乎比~/更好。zshrc中。

高海拔及更早

默认shell是bash，您可以编辑文件~/。Bash_profile和添加别名:

纳米~ / . bash_profile 别名py = python

然后按ctrl+x, y, enter保存。有关这些配置的更多信息，请参阅这篇文章。在~/中使用别名设置会更好一些。Bashrc，然后source ~/。~/.bash_profile中的Bashrc。在~ /。Bash_profile看起来就像这样:

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

在root - ex用户下创建bash_profile

/user/username/.bash_profile

打开的文件

vim ~ / . bash_profile

添加别名为ex.(保存并退出)

alias mydir="cd ~/Documents/dirname/anotherdir"

在新终端中输入mydir -它应该会打开

/user/username/Documents/dirname/anotherdir

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.
