The command "setsid ${program}" is used to start a program in a new session and detach it from the current terminal session.
Here's how it works:
-
"setsid" is a command that creates a new session and sets the current process as its leader. This ensures that the program runs in its own session and is not affected by the current terminal session or any signals that may be sent to it.
-
"${program}" is a placeholder for the name or path of the program you want to start. You need to replace "${program}" with the actual name or path of the program you want to run.
By using "setsid" before starting the program, you ensure that the program is detached from the current terminal session, meaning it will continue to run even if you close the terminal or log out. It also prevents any signals or input/output redirection from affecting the program.
This command is commonly used when you want to run a program in the background, without any association with the current terminal session.
