john:tldr:95eae

This command is using the John the Ripper password cracking tool to crack passwords. Here is the breakdown of the command:

• john is the executable command for John the Ripper.
• --wordlist=${path-to-wordlist-txt} specifies the wordlist file to be used for password cracking. ${path-to-wordlist-txt} is a placeholder that needs to be replaced with the actual path to the wordlist file in your system. The wordlist file contains a list of possible passwords that are tried one by one until a match is found.
• ${path-to-hashes-txt} is the path to the file containing the password hashes that need to be cracked. This file is usually obtained by extracting password hashes from a system or database.

In summary, this command tells John the Ripper to use a specified wordlist file and password hashes file for attempting to crack passwords. The wordlist file provides a list of possible passwords, while the password hashes file contains the encrypted password representations that need to be cracked.
