Using Linux to Easily Retrieve Process Names for Optimal System Management（linux获取进程名）
Linux is commonly known for being a reliable and secure operating system for many production-level applications such as web servers, cloud computing, and IoT solutions. It is also used by millions of users all over the world as their primary computer operating system.
Linux is an open-source platform and its source code has been studied and improved upon by countless developers all over the world, making it the most secure and customizable operating system available. One of the benefits of being able to access and customize the source code of a Linux OS is the ability to easily retrieve process names for optimal system management. This can be a useful tool for controlling which services or processes are running or for system diagnostics.
Retrieving process names for Linux-based systems can be achieved using the command line tool “ps”. This command can be used to query what processes are running or to see the key metrics for any given process. To use it to retrieve process names, you can use the options -A, -U, and -N.
The -A option will show all processes related to the current user, while the -U option will show all processes owned by a particular user. The -N option, which lists processes in numerical order, provides an easy way to determine the names of particular processes.
For example, if we wanted to look up the process name associated with a particular process ID, we could execute the following command:
ps -U -N -p
The output of this command would tell us the name of the process associated with the given PID. It would also provide other helpful information such as the process’s CPU and memory utilization, as well as the command-line arguments or parameters it was started with.
With this method, you can easily look up process names and determine how much resources a particular process is using, or how it was launched. This can be particularly helpful when troubleshooting system performance issues or when trying to determine the source of strange behavior.
In summary, the ability to access and customize the source code of a Linux OS makes it possible to easily retrieve process names for optimal system management. You can use the command-line tool “ps” with options -A, -U, and -N to query the name of a particular process as well as its resource utilization. This makes it easier to diagnose performance issues and to ensure that processes are running as they should.
