Use ps -o pri . Specify the process id with -p 1337 . Or, use -e to list all processes. If you have a cut-down Linux distribution where ps and top does not give you priority information, you can parse the stat file of proc for your process ID to get the priority information.

What is process priority in Linux?
Priority value — The priority value is the process’s actual priority which is used by the Linux kernel to schedule a task. In Linux system priorities are 0 to 139 in which 0 to 99 for real-time and 100 to 139 for users. Nice value — Nice values are user-space values that we can use to control the priority of a process.
What is the default priority of a process?
The nice value of a process can have a range between -20 (highest priority) to +19 (lowest priority); by default, its value is 0. If the nice value of a process is lower, it gets a higher priority, which means the CPU will execute that process more often.
Which command is used to set the priority of process?
nice command is used to start a process with specified nice value, which renice command is used to alter priority of running process.

What is process priority?
The higher the priority, the more processor time allocated to the application. In Windows, the priority levels range from 0 (lowest priority) to 31 (highest priority). Priorities are applied to threads by combining the priority class of the process with the priority level of the thread.
What are the types of processes in Linux?
There are two types of Linux process, normal and real time. Real time processes have a higher priority than all of the other processes. If there is a real time process ready to run, it will always run first. Real time processes may have two types of policy, round robin and first in first out.
What is PS EF command in Linux?
This command is used to find the PID (Process ID, Unique number of the process) of the process. Each process will have the unique number which is called as PID of the process.
What is PR in top command?
From the top and htop outputs above, you’ll notice that there is a column called PR and PRI receptively which shows the priority of a process. This, therefore, means that: NI – is the nice value, which is a user-space concept, while. PR or PRI – is the process’s actual priority, as seen by the Linux kernel.
Which processes have the highest priority?
A process’ priority can range between 0 (lowest priority) and 127 (highest priority). User mode processes run at lower priorities (lower values) than system mode processes. A user mode process can have a priority of 0 to 65, whereas a system mode process has a priority of 66 to 95.
What is Process Priority in Windows?
Windows shares processor resources between all running processes based upon their priority level. If a process (application) has a higher priority level, it gets more processor resources for better performance compared to a process having lower priority.
Which type of processes are a high priority processes?
The processes with higher priority should be carried out first, whereas jobs with equal priorities are carried out on a round-robin or FCFS basis. Priority depends upon memory requirements, time requirements, etc.
How can we change process priority?
Change the priority of a process
- Go to the Processes tab and click on the process you want to have a different priority.
- Right-click the process, and use the Change Priority menu to assign the process a higher or lower priority.
How do I change the priority of a process?
- Start Task Manager (Right Click on the Start Bar and select Task Manager)
- Click on the Processes tab.
- Right Click on the required process and select “Set Priority”
- You can then select a different priority.
- Close Task Manager.
What is the use of Nice () command?
Description. The nice command lets you run a command at a priority lower than the command’s normal priority. The Command parameter is the name of any executable file on the system. If you do not specify an Increment value the nice command defaults to an increment of 10.
