Short: "yq d [--inplace/-i] [--doc/-d index] sample.yaml a.b.c",
Example: `
yq delete things.yaml 'a.b.c'
yq delete things.yaml 'a.*.c'
yq delete things.yaml 'a.(child.subchild==co*).c'
yq delete things.yaml 'a.**'
yq delete --inplace things.yaml 'a.b.c'
yq delete --inplace -- things.yaml '--key-starting-with-dash' # need to use '--' to stop processing arguments as flags
yq d -i things.yaml 'a.b.c'
`,
Long: `Deletes the nodes matching the given path expression from the YAML file.
Outputs to STDOUT unless the inplace flag is used, in which case the file is updated instead.
