Use: "write [yaml_file] [path_expression] [value]",
|
||
|
|
Aliases: []string{"w"},
|
||
|
|
Short: "yq w [--inplace/-i] [--script/-s script_file] [--doc/-d index] sample.yaml a.b.c newValue",
|
||
|
|
Example: `
|
||
|
|
yq write things.yaml 'a.b.c' true
|
||
|
|
yq write things.yaml 'a.*.c' true
|
||
|
|
yq write things.yaml 'a.**' true
|
||
|
|
yq write things.yaml 'a.(child.subchild==co*).c' true
|
||
|
|
yq write things.yaml 'a.b.c' --tag '!!str' true # force 'true' to be interpreted as a string instead of bool
|
||
|
|
yq write things.yaml 'a.b.c' --tag '!!float' 3
|
||
|
|
yq write --inplace -- things.yaml 'a.b.c' '--cat' # need to use '--' to stop processing arguments as flags
|
||
|
|
yq w -i things.yaml 'a.b.c' cat
|
||
|
|
yq w -i -s update_script.yaml things.yaml
|
||
|
|
yq w things.yaml 'a.b.d[+]' foo # appends a new node to the 'd' array
|
||
|
|
yq w --doc 2 things.yaml 'a.b.d[+]' foo # updates the 3rd document of the yaml file
|
||
|
|
`,
|
||
|
|
Long: `Updates the yaml file w.r.t the given path and value.
|
||
|
|
Outputs to STDOUT unless the inplace flag is used, in which case the file is updated instead.
|
||
|
|
|
||
|
|
Append value to array adds the value to the end of array.

Update Scripts:

Note that you can give an update script to perform more sophisticated update. Update script

format is list of update commands (update or delete) like so:

path: b.c

#great

things: frog # wow!
|

|
|
- command: delete

path: b.d
