Automatically Set Ownership to www-data Using incron If you want to ensure that any file or folder created inside /var/www/html is automatically owned by www-data , you can use incron . Incron works similarly to cron, but instead of running based on time schedules, it monitors filesystem events such as: File or directory creation File modifications Attribute changes File deletions Step 1 — Install incron Install incron using: sudo apt-get install incron Step 2 — Allow Root to Use incron By default, not all users are allowed to use incron. You must explicitly grant permission. Open the file: sudo vim /etc/incron.allow Add the following line: root Save and exit. Step 3 — Configure incrontab Edit the incrontab for root: sudo incrontab -u root -e Add this line: /var/www/html IN_CREATE /bin/chown -R www-data:www-data /var/www/html/ Save and exit. How It Works With this configuration, whenever a new file is created inside /var/www/html , its ownership will auto...

Berikut adalah contoh bagian-bagian dari struktur file Json, dengan mengetahui bagian-bagian tersebut mempermudah untuk memahami dan memilah data. Sebelumnya sudah pernah juga menulis tentang parsing file json ini menggunakan perintah linux jq , jika tertarik ini link nya  https://nciptandani.blogspot.com/2021/11/cara-parsing-file-json-dengan-jq.html Pada dasarnya file json terdiri dari key dan value, key berupa string. Satu object file Json bisa terdiri dari berbagai tipe data, seperti string, object, array, int, null, boolean sebagai value nya.   https://docs.exivity.com/data-pipelines/extract/parslets Cara membaca file Json di Python https://pynative.com/python-json-load-and-loads-to-parse-json/ https://www.freecodecamp.org/news/python-read-json-file-how-to-load-json-from-a-file-and-parse-dumps/ https://python.plainenglish.io/data-extraction-parse-a-3-nested-json-object-23cb978b66ad File Json berikut terdiri dari key competitors terdapat value berupa array yang berisi usern...

File json banyak ditemui dalam kegiatan sehari-hari baik programmer, system/network engineer, dll. File Json mempunyai struktur, pada tutorial ini hanya akan membahas bagaimana memparsing/mengurai file Json, misalnya hanya mengambil bagian data-data yang dibutuhkan saja.  Disini menggunakan command jq, sebelum menggunakan perintah ini bisa menginstall terlebih dahulu, disini menggunakan linux, #sudo apt install jq Gambar dibawah ini bagus memperlihatkan bagaimana format file json, isi file json pada dasarnya berisi data type pada umumnya. https://www.shapediver.com/blog/json-objects-explained Contoh ada file json dibawah ini: score.json {   "eventname": "Lomba Siswa",   "modulename": "Linux Project",   "competitors": [     {       "username": "competitor1",       "score": "98",       "institution": "SMK Negeri 4"     },     {       "username": "competitor2",...
