The command "wait ${pid}" is used to wait for a specific process to finish executing before proceeding with the next set of commands in a script or program.
- "wait" is a shell command that waits for one or more processes to complete their execution.
- "${pid}" is a placeholder that represents the process ID (PID) of the process you want to wait for. The PID is a unique identifier assigned to every running process in a system.
By using this command, the script or program will pause until the specified process with the given PID has completed. This is useful if you need to ensure that certain tasks or dependencies are completed before continuing the execution.
