- Store each of the next lines you enter as values of an array:
|
||||
|
||||
`read -a {{array}}`
|
||||

- Specify the number of maximum characters to be read:
|
||||

||||
`read -n {{character_count}} {{variable}}`
|
||||
|

- Assign multiple values to multiple variables:
|
||||
|
||||
`{{echo "The name is Bond"}} | read {{_ variable1 _ variable2}}`
|
||||
|
||||

||||
|
||||
`read -r {{variable}}`
|
||||
|
||||
- Read `stdin` or file and perform an action on every line:
|
||||
- Display a prompt before the input:
|
||||
|
||||
`read -p "{{Enter your input here: }}" {{variable}}`
|
||||
|
||||
- Do not echo typed characters (silent mode):
|
||||
|
||||
`read -s {{variable}}`
|
||||
|
||||
- Read `stdin` and perform an action on every line:
|
||||
|
||||
