# read
> BASH builtin for retrieving data from standard input
- Store data that you type from the keyboard:
`read {{variable}}`
- Store each of the next lines you enter as values of an array:
`read -a {{array}}
- Enable backspace and GNU readline hotkeys when entering input with read:
`read -e {{variable}}
- Specify the number of maximum characters to be read:
`read -n {{character_count}} {{variable}}
- Use a specific character as a delimiter instead of a new line:
`read -d {{delimiter}} {{variable}}
