Basic

Given a sample.yaml file of:

b:
  c: 2

then

yaml sample.yaml b.c

will output the value of '2'.

Handling '.' in the yaml key

Given a sample.yaml file of:

b.x:
  c: 2

then

yaml sample.yaml \"b.x\".c

will output the value of '2'.

Arrays

You can give an index to access a specific element: e.g.: given a sample file of

b:
  e:
    - name: fred
      value: 3
    - name: sam
      value: 4

then

yaml sample.yaml b.e[1].name

will output 'sam'

Updating yaml

Given a sample.yaml file of:

b:
  c: 2

then

yaml w sample.yaml b.c cat
