The command "setsid --fork ${program}" is used to run a program in the background as a new session leader.

Explanation:

• "setsid" is a command used to run a program in a new session.
• "--fork" is an option that tells setsid to fork a new process before executing the program, effectively detaching it from the current terminal session.
• "${program}" represents the actual program you want to run. You need to replace it with the name or path of the executable you wish to execute.

When this command is executed, it creates a new session and forks a child process. The child process then executes the specified program while becoming the session leader. This means the program will run independently, even if the current shell session is terminated or closed.

By using setsid --fork, you can run a program detached from the current terminal session, allowing it to continue running even after you log out or close the terminal.
