Examples

This first example has a result of [ "b!=d" ]:

> json {"a":"b", "b": {"c":"d"}} | format {a}!={b.c}

The result of the next command is [ "only select >2<" ]:

> json {"b": {"c":[0,1,2,3]}} | format only select >{b.c[2]}<

The following command results in [ "only select >2<" ]:

> json {"b": {"c":[0,1,2,3]}} | format only select >{b.c[2]}<

And the below example has a result of [ "null:null:null" ]:

> json {} | format {a}:{b.c.d}:{foo.bla[23].test}

This command writes the result of search all in JSON format to a file named out.json:

> search all | format --json | write out.json
