john:tldr:3bb50

This command is using the "john" program to display password hashes and their associated usernames for a specified list of users.

Here is a breakdown of the command:

• "john" is the name of the program that is being executed. It is commonly used for password cracking and hash analysis.
• "--show" is an option/command-line flag that tells the "john" program to display the cracked passwords in a human-readable format.
• "--users=${user_ids}" is another option that specifies the user IDs for which password hashes should be displayed. The "${user_ids}" is a variable placeholder that needs to be replaced with the actual user IDs you want to analyze.
• "${path-to-hashes}" and "${path-to-other-hashes}" are also variables that represent the paths to the files containing password hashes. The "* " part implies that the specified paths can be multiple files or a wildcard pattern representing multiple files.

To use this command effectively, you would replace "${user_ids}" with the desired user IDs and "${path-to-hashes}" and "${path-to-other-hashes}" with the actual paths to the files containing the password hashes you want to analyze.
