Hi , this is funny Linux trick. if you give string, it will give banner text effect depending on the string.
For example:
if your string value is hackers, then it will generate the following :

Requirements:
- Linux
- Internet
- Open the Terminal
- Type
sudo apt-get install sysvbanner - It will install the banner
- Now type
banner HACKERS
Change HACKERS with any string(like HELLO,YOURNAME…..)
