linux:process:check:running
Check if a given process is running.
$ ps aux | grep ${process_name}
try on your machine
This command is used to search for a process by its name. Here's a breakdown of the different parts of the command:
ps
: This command displays information about running processes on the system.aux
: This option tellsps
to display all processes owned by any user and show additional details about the processes.|
: This symbol is called a pipe character and it is used to redirect the output of one command as the input to another command.grep
: This command is used to search for a specific pattern in the input and print any matching lines.${process_name}
: This is a variable that represents the name of the process you want to search for.
So when you run the command ps aux | grep ${process_name}
, it will display a list of all running processes on the system with additional details like the process ID, CPU usage, and memory usage. The output is then piped to the grep
command which searches for lines that contain the ${process_name}
variable and prints them out. This allows you to quickly find a specific process and see its details without having to manually search through the entire list of processes.

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