我需要运行Postgres数据库并为此目的创建一个别名。具体工作思路如下:

$ nano ~/.bash_profile 

# in the bash_profile, insert the following texts:

alias pgst="pg_ctl -D /usr/local/var/postgres start"
alias pgsp="pg_ctl -D /usr/local/var/postgres stop"


$ source ~/.bash_profile 

### This will start the Postgres server 
$ pgst

### This will stop the Postgres server 
$ pgsp

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

脚本和程序的配置文件是~/。bashrc和使用Terminal时加载的配置文件是~/.bash_login。

我认为最好的方法是把所有东西都放在~/.bashrc中。

对于您的特定问题，只需输入(这将覆盖任何现有的~/.bashrc):

echo "alias blah=\"/usr/bin/blah\"" >>~/.bashrc

输入终端和~/。Bashrc文件将与您的新别名一起创建。之后，只需编辑文件，添加新的别名，函数，设置等。

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！

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:
