You can affect how jq reads and writes its input and output
using some command-line options:
* `--version`/`-V`:
* `--null-input` / `-n`:
Output the jq version and exit with zero.
Don't read any input at all. Instead, the filter is run once
using `null` as the input. This is useful when using jq as a
simple calculator or to construct JSON data from scratch.
* `--seq`:
Use the `application/json-seq` MIME type scheme for separating
JSON texts in jq's input and output. This means that an ASCII
RS (record separator) character is printed before each value on
output and an ASCII LF (line feed) is printed after every
output. Input JSON texts that fail to parse are ignored (but
warned about), discarding all subsequent input until the next
RS. This mode also parses the output of jq without the `--seq`
option.
* `--stream`:
Parse the input in streaming fashion, outputting arrays of path
and leaf values (scalars and empty arrays or empty objects).
For example, `"a"` becomes `[[],"a"]`, and `[[],"a",["b"]]`
becomes `[[0],[]]`, `[[1],"a"]`, and `[[2,0],"b"]`.
This is useful for processing very large inputs. Use this in
conjunction with filtering and the `reduce` and `foreach` syntax
to reduce large inputs incrementally.
* `--slurp`/`-s`:
Instead of running the filter for each JSON object in the
input, read the entire input stream into a large array and run
the filter just once.
* `--raw-input`/`-R`:
* `--raw-input` / `-R`:
Don't parse the input as JSON. Instead, each line of text is
passed to the filter as a string. If combined with `--slurp`,
then the entire input is passed to the filter as a single long
string.
* `--null-input`/`-n`:
* `--slurp` / `-s`:
Don't read any input at all! Instead, the filter is run once

* `--tab`:

* `--indent n`:
Use the given number of spaces (no more than 7) for indentation.
* `--color-output` / `-C` and `--monochrome-output` / `-M`:
By default, jq outputs colored JSON if writing to a
terminal. You can force it to produce color even if writing to
a pipe or a file using `-C`, and disable color with `-M`.
Colors can be configured with the `JQ_COLORS` environment
variable (see below).
* `--ascii-output` / `-a`:
jq usually outputs non-ASCII Unicode codepoints as UTF-8, even
if the input specified them as escape sequences (like
"\u03bc"). Using this option, you can force jq to produce pure
ASCII output with every non-ASCII character replaced with the
equivalent escape sequence.
* `--unbuffered`:
Flush the output after each JSON object is printed (useful if
you're piping a slow data source into jq and piping jq's
output elsewhere).
* `--sort-keys` / `-S`:
Output the fields of each object with the keys in sorted order.
