pidof

If you need an efficient program that can quickly provide you with the PID number of a specific process name, then pidof is the tool you've been looking for. This small program functions similarly to using grep, as it returns all matches for the given process name. Even if there are multiple processes with the same name, pidof will list all possible matches.

Installing the program is a straightforward process. You can either use "sudo ./installer" from the directory or copy the pidof program file to the desired location. Additionally, you can install the man page if you wish to do so.

If you wish to customize the installation path, you can achieve this using the installer. You simply need to give the installer the path where you want to install the program as an argument. For example, if you want to install pidof to /usr, you can enter "sudo ./installer /usr" to install it to that location instead of the default /usr/local path. Overall, pidof is a useful program that is easy to use and install.
