Here is a breakdown of some of the information provided in each line of /proc/meminfo: To view the “/proc/meminfo” file, open a terminal and type:.The first few lines provide summary information about memory usage, while the remaining lines provide more detailed information about specific areas of memory. Each line in the file represents a different aspect of memory usage. The /proc/meminfo file provides detailed information about memory usage on the Linux system. This method again relies on the terminal to display the memory usage. Method 3: Using the “cat” /proc/meminfo Command and finally, the command that is being executed.time each task or process has been running for.overall memory usage by each task in percentage.CPU usage by each process in percentage.S which is for displaying the process state.There are even more details that are displayed in the processes area details such as PID, USER group the processes belong to, Process priority, Process niceness, and Memory usage by processes that can be further divided into: In addition to displaying the overall memory utilization, htop also displays CPU utilization by each core, the swap space, the number of tasks that are running currently, and load average by the tasks that are running in the 1-minute, 5 minute and 15-minute time period, and the total uptime of the machine. Htop displays a real-time updated list of processes that presently running which is ordered by the CPU usage that is being consumed by each of the processes. Once “htop” is installed, open a terminal and type: htop Htop
