pidof: List a single process ID with given name.
$ pidof -s ${bash}
try on your machine
The command "pidof -s ${bash}" is used to find the process ID (PID) of the running instance of the "bash" shell. Here's a breakdown of the command:
- "pidof" is a command that is used to find the PID of a running process.
- "-s" is an option for "pidof" that is used to only display the PID if there is a single instance of the process running. It ensures that only one PID is returned, rather than listing multiple PIDs if there are multiple instances of the process running.
- "${bash}" is a variable that represents the name of the process we want to find the PID for. In this case, it is the "bash" shell.
So, when the "pidof -s ${bash}" command is executed, it searches for the PID of the running instance of the "bash" shell, and if found, returns the PID. If there are multiple instances of the "bash" shell running, it will not return anything.

never run a command you are not sure if it is safe.
