Usage ​

NOTE

Using both --line and --list at the same time seems to not work.

Read file line by line in loop:

fish
while read --line keyvalue
  export $keyvalue
end <~/.local/environment

Read the output of a command line by line:

fish
cmd | while read --line line
    echo $line
end

Read input from the user using a customized prompt:

fish
read --prompt-str 'Are you sure? [y/N] '
