I have below JSON file and would like to update the values of these keys --resType and --LogLevel using jq.
{
"--resType": "FILE",
"--LogLevel": "INFO"
}
To do that, I am using below command.
./jq .--resType=Test config.json>test.json
But, I see an error that says
"jq: error: Test/0 is not defined at , line 1:".
"jq: 2 compile errors"

"Invalid numeric literal" error from jq trying to modify JSON with variable
(1 answer)

Here is the example json
{
"app": "K8s",
"version": "1.8",
"date": "2018-10-10"
}
In order to get the value of app, I can do this in jq as
jq '.app'
But what I want is, I want to pass the key to jq as a bash variable, i.e
bash_var="app"
jq '."${bash_var}"'
I'm getting the output as null instead of the value. What is the correct syntax to achieve this?
First, you need to port the bash variable into jq's context usign the --arg flag and access it inside the [..]
jq --arg keyvar "$bash_var" '.[$keyvar]' json

Please I am trying to pass a html string as value to the below powershell function "set-content" from azure cli but I don't think I am escaping the double quotes correctly. The value parameter only accepts strings, somehow, it does not get executed at the target machine with the double quote. I get the below error. please help!
az vm extension set --name CustomScriptExtension --vm-name MyWindowsVM -g TestsandRG --publisher Microsoft.Compute --settings '{"commandToExecute": "powershell set-Content -Path \"C:\\inetpub\\wwwroot\\Default.htm\" -Value \"<html><body><h2>Welcome to Azure!

It seems unlikely this hasn't been asked, but I can not find it anywhere.
I am trying to filter response from elasticsearch and need to reference the #timestamp field. However, jq uses # to specify formatters and I find nothing in documentation about how to escape the # character.
$ jq '.hits.hits[] | ._source.#timestamp' < debug.response.json
jq: error: syntax error, unexpected $end, expecting QQSTRING_START (Unix shell quoting issues?) at <top-level>, line 1:
.hits.hits[] | ._source.#timestamp
jq: 1 compile error
You can use the generic object index syntax, like:
.hits.hits[]._source["#timestamp"]

I have a JSON body. I would like to obtain the value of "access_token". I would like to use grep in bash. The grep I used doesn't not work.
I tried the following but it provides me a blank result.
HTTP_BODY=$(echo $HTTP_RESPONSE | grep ^"access_token":" ","experies_in$ )
I want only to obtain the access_token value, i.e.:

I have a URL
http://localhost/status?json
Which is PHP-FPM's status page, it outputs this
{
"pool":"www",
"process manager":"dynamic",
"start time":1526919087,
"start since":69780,
"accepted conn":403320,
"listen queue":0,

"listen queue len":0,
"idle processes":21,
"active processes":6,
"total processes":27,
"max active processes":200,
"max children reached":1,
"slow requests":0
}
I want to turn this JSON into an Array in Bash, so I can do a loop around it to check for stuff, I've heard JQ can parse this, but I'm unsure in BASH how I can convert it to a useable array.
Any ideas?
