qrencode: Convert input from pipe to a QR code and print it in terminal.
$ echo ${string} | qrencode -t ansiutf8
try on your machine

This command generates a QR code from the value stored in the variable "string" and displays it in the terminal.

Here's a breakdown of the command:

  1. echo ${string}: This part of the command prints the value of the variable "string" to the standard output. The ${string} syntax is used to access the value of the variable.
  2. |: This is a pipe symbol, which is used to redirect the output of the previous command as the input for the next command.
  3. qrencode -t ansiutf8: The piped output from the previous command is passed to the qrencode command. qrencode is a utility used to generate QR codes. The -t ansiutf8 flag specifies the output format as ANSI with UTF-8 encoding, which means the QR code will be displayed as ASCII characters in the terminal.

So, all together, this command prints the value of the "string" variable and then generates the corresponding QR code, displaying it in the terminal using ASCII characters.
