Put document

Description

This command allows you to modify data at a given selector.

It generally works in the same way as put, but allows you to write entire documents with a single command.

Note that put document will completely overwrite any existing data at the given selector.

Usage

dasel put document -f <file> -d <document-parser> <selector> <document>

Flag

Description

<document>

The document you want to put, as a marshaled/encoded string.

This is required.

-d, <document-parser>

Specify the parser to use when reading the document value.

If no value is provided, the read parser is used.

See supported file types.

-f, --file

Specify the file to query. This is required unless you are piping in data.

If piping in data you can optionally pass -f stdin/-f -.

-o, --out

Specify the output file. If present, results will be written to the given file. If not present, results will be written to the input file (or stdout if none given).

To force output to be written to stdout, pass -o stdoutor-o -.

-r, --read

Specify the parser to use when reading the input data.

This is required if you are piping in data, otherwise dasel will use the given file extension to guess which parser to use.

See supported file types.

-w, --write

Specify the parser to use when writing the output data.

If not provided dasel will attempt to use the --out and --read flags to determine which parser to use.

See supported file types.

-p, --parser

Shorthand for -r <value> -w <value>

-m, --multiple

Tells dasel to put multiple items.

See multiple.

-s, --selector, <selector>

Specify the selector to use. See selectors for more information.

If no selector flag is given, dasel assumes the first argument given is the selector.

This is required.

-c, --compact

This tells dasel to output compact data where possible. E.g. not pretty printing JSON.

--merge-input-documents

See merge input documents.

Example

Put YAML document into JSON

echo '{"people":[]}' | dasel put document -p json -d yaml '.people.[]' 'name: Tom
colours:
- red
- green
- blue'
{
"people": [
{
"colours": [
"red",
"green",
"blue"
],
"name": "Tom"
}
]
}
