Install Jq on Ubuntu 22.04 LTS
Step 1. First, before you start installing any package on your Ubuntu server, we always recommend making sure that all system packages are updated.
sudo apt update sudo apt upgrade sudo apt install build-essential libpcap-dev libpcre3-dev libnet1-dev zlib1g-dev luajit hwloc libdnet-dev libdumbnet-dev bison flex liblzma-dev openssl libssl-dev pkg-config libhwloc-dev cmake cpputest libsqlite3-dev uuid-dev libcmocka-dev libnetfilter-queue-dev libmnl-dev autotools-dev libluajit-5.1-dev libunwind-dev libfl-dev
Step 2. Install Jq on Ubuntu.
Snort installation is quite easy and straightforward since the Jq package is accessible in the repositories of the majority of Linux distributions. Now You can follow the steps given below for installing Jq:
sudo apt install jq
When the installation is finished, check Jq version:
jq --version
Step 3. Testing Jq on Ubuntu.
Let’s say we have JSON data stored in the test.json file:
echo '{"status":"success","data":[{"name":"Meilana","age":25},{"name":"Maria","age":29}]}' > test.json
The Jq tool supports various filters that can be applied to JSON data. For example, the dot . filter prints unchanged but nicely formatted JSON:
jq '.' test.json
Output:
{
"status": "success",
"data": [
{
"name": "Meilana",
"age": 25
},
{
"name": "Maria",
"age": 29
}
]
}
We can retrieve a particular field of a JSON object or an element of a JSON array as follows:
jq '.data[1].name' test.json
Output:
"Meilana"
