Aliases

Aliases in your terminal make shortcuts a lot easier when you're typing, use them properly

• Setting #1 : default text editor alias since my editor of choice is BBEdit:

alias bbedit "open -a bbedit"

then in the terminal type

bbedit FILE_NAME

Aliases within your .bashrc file is just endlessly useful. This stackOverflow answer gets a lot of it right.

Shebang

This is a command that you often see at the top of the command but you never know what it does. This is used for every single type of Unix-like dydyem and is used to interpet an executable file. It is usually starting with #!/ and leads to somewhere else.

Example:

#!/usr/bin/env sh 
Hello World! 

& you run the executable after touch creating one by:

chmod +x name_of_the_file
