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

您可能希望在主目录中编辑.bashrc文件。

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

我认为这是正确的方式:

1)去终点站。开放的~ / . bashrc。如果不存在则添加

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

2)打开~/.bash_aliases。如果不存在:touch ~/。打开~/.bash_aliases &&

3)增加新的别名 -编辑.bash_aliases文件并重启终端或打印source ~/.bash_aliases - print echo "alias clr='clear'" >> ~/。Bash_aliases && source ~/。Bash_aliases你的别名是别名clr='clear'。

4)添加行源~/。bash_alias到~/。bash_profile文件。它需要在终端的每个init中加载别名。

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！

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
