CodePudding user response：

It's easier with awk or perl

$ cat file.yml
for:
  bar1:
    key1: value1
  bar2:
    key2: value2
bar:
  foo:
    foobar:
      key3: value3
      key4: value4

$ perl -pe 'BEGIN { @new = qw<one two three> } s/^ {4,6}\S : \K. /shift @new/e if @new' file.yml
for:
  bar1:
    key1: one
  bar2:
    key2: two
bar:
  foo:
    foobar:
      key3: three
      key4: value4

CodePudding user response：

You could just do the obvious thing and use directories.

mkdir -p bar1/key1
echo "hello" > ./bar1/key1/value1

Editing and replacing value1 is extremely easy with that structure.
