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 {{new_delimiter}} {{variable}}
