+<p>Note: it is important to mind the shell&#8217;s quoting rules. As a general rule it&#8217;s best to always quote (with single-quote characters) the jq program, as too many characters with special meaning to jq are also shell meta-characters. For example, <code>jq

+defined</code>. When using the Windows command shell (cmd.exe) it&#8217;s best to use double quotes around your jq program when given on the command-line (instead of the <code>-f program-file</code> option), but then double-quotes in the jq program need backslash escaping.</p>
