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

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?

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

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！

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。

我只是打开zshrc与sublime，并编辑它。

subl .zshrc

在sublime上加上这个:

alias blah="/usr/bin/blah"

在terminal中执行如下命令:

source ~/.zshrc

完成了。
