pgrep:tldr:dd734
The command "pgrep" is used to search running processes on a Linux system based on their names.
In this specific command, the "--full" option is used to search for a process that matches the full command-line string of the process rather than just the process name.
The "${process_name} ${parameter}" syntax is using variables to define the search criteria.
"${process_name}" should be replaced with the name of the process you want to search for. "${parameter}" should be replaced with any additional parameters or arguments that the process may have.
For example, if you want to find a running process called "example", with an additional parameter "param", you would replace "${process_name} ${parameter}" with "example param".
The command will then search for the process that matches the full command-line string. And if a matching process is found, "pgrep" will return the process ID (PID) of the process.
