read

BASH builtin for retrieving data from standard input. More information: https://manned.org/read.1p.

• 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}}
   
• 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}}
   
• Do not let backslash (\) act as an escape character:
   
  read -r {{variable}}
   
• 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:
   
  while read line; do echo "$line"; done
