How To Parse JSON String Via Command Line On Linux

If you often deal with JSON-formatted texts from the command line or in shell scripts, you may wonder if there is any command-line utility which can parse JSON string. A command-line JSON parser can be handy when you test or debug JSON web services. You can feed JSON-formatted responses from web services into the command-line JSON parser, thereby easily inspecting otherwise hard-to-read JSON responses or extracting individual objects from them. In this tutorial, I will describe how to parse JSON string from the command line. On Linux, there is a command-line JSON processor called jq which does exactly that. Using jq, you can parse, filter, map, and transform JSON-structured data effortlessly. You can simply download its binary (available for 32-bit and 64-bit system separately) as follows. On 32-bit system, replace the above wget command with the following. The jq binary is also available for Windows and OS X platforms, and its full source code is released under the MIT license. The following examples illustrate how to parse JSON-structured data with jq. If you want to parse JSON string inside your program (e.g., written in Python or Perl), you can refer to these Python and Perl tutorials. If what you are interested in is to check if a given JSON string conforms to JSON schema, this tutorial may be useful.
This is one of the main uses of Google Maps JSON files. By customizing the appearance of the map, you can make it blend seamlessly with the rest of your website, enhancing the overall user experience. What are some common issues that can occur when working with Google Maps JSON files? Some common issues that can occur when working with Google Maps JSON files include syntax errors in the JSON file, problems with the Google Maps JavaScript API, and issues with the way the map is displayed on the webpage. These issues can usually be resolved by checking the JSON file for errors, ensuring that the API is being used correctly, and adjusting the CSS of the webpage. How can I troubleshoot problems with my Google Maps JSON file? Troubleshooting problems with your Google Maps JSON file can involve several steps. First, check the JSON file for syntax errors. Next, ensure that the Google Maps JavaScript API is being used correctly.
This feature is obsolete in GNU make, because the general feature of rule chaining (see Chains of Implicit Rules) allows one pattern rule for installing members in an archive (see Implicit Rule for Archive Member Targets) to be sufficient. The arrangement of lines and backslash/newline combinations in recipes is retained when the recipes are printed, so they appear as they do in the makefile, except for the stripping of initial whitespace. The following features were inspired by various other versions of make. In some cases it is unclear exactly which versions inspired which others. Pattern rules using ‘%’. This has been implemented in several versions of make. We’re not sure who invented it first, but it’s been spread around a bit. See Defining and Redefining Pattern Rules. Rule chaining and implicit intermediate files. This was implemented by Stu Feldman in his version of make for AT&T Eighth Edition Research Unix, and later by Andrew Hume of AT&T Bell Labs in his mk program (where he terms it “transitive closure”).
Note this is not the same as recursion (counted by the MAKELEVEL variable). You should not set, modify, or export this variable. When make starts it will check whether stdout and stderr will show their output on a terminal. TERMERR, respectively, to the name of the terminal device (or true if this cannot be determined). If set these variables will be marked for export. These variables will not be changed by make and they will not be modified if already set. If you invoke a sub-make and redirect its stdout or stderr it is your responsibility to reset or unexport these variables as well, if your makefiles rely on them. The first character of the value of this variable is used as the character make assumes is introducing a recipe line. If the variable is empty (as it is by default) that character is the standard tab character. The value of .RECIPEPREFIX can be changed multiple times; once set it stays in effect for all rules parsed until it is modified.
