How to define a variable in a BASH script by using a JSON file online?
Hello,
I would like to modify an existing script of mine that uses a manually defined "MCVERSION" variable and make it define that variable instead based on this JSON file stored online: https://s3.amazonaws.com/Minecraft.D.../versions.json
Within that JSON, I 'm looking for this information:
I want $MCVERSION to equal the "latest/release" value above (in this case, MCVERSION=1.7.2). I'm perfectly OK with pulling the JSON file down locally first via "wget" command. In fact, I'd prefer that so I can reference it if needed if my script fails (in case they change their JSON file format).
Here is my script (not that it matters too much for this example, I doubt).
Currently, the script results in creating this file:
/home/mcmaps/.minecraft/versions/1.7.2/1.7.2.jar
The goal is to do that without ever having to manually modify the MCVERSION variable in this script.

Hi, Unix Gurus,
In our existing file, there is a script like
#!/bin/sh
step=${1:-0}
cur_step=10

My question is what's "${1:-0}" mean? I know it defines a variable but I don't know what's (1:-0) mean?
:wall:
Thanks in advance. (2 Replies)

test::json
Test::JSON(3pm) User Contributed Perl Documentation Test::JSON(3pm)NAME
Test::JSON - Test JSON data
VERSION
Version 0.11
SYNOPSIS
use Test::JSON;
is_valid_json $json, '... json is well formed';
is_json $json, $expected_json, '... and it matches what we expected';
EXPORT
o is_valid_json
o is_json
DESCRIPTION
JavaScript Object Notation (JSON) is a lightweight data interchange format. Test::JSON makes it easy to verify that you have built valid
JSON and that it matches your expected output.
See <http://www.json.org/> for more information.
TESTS
is_valid_json
is_valid_json $json, '... json is well formed';
Test passes if the string passed is valid JSON.
is_json
is_json $json, $expected_json, '... and it matches what we expected';
Test passes if the two JSON strings are valid JSON and evaluate to the same data structure.
Test::Differences is used to provide easy diagnostics of why the JSON structures did not match. For example:
Failed test '... and identical JSON should match'
in t/10testjson.t at line 14.
