Determining the amount of RAM (Random Access Memory) installed on a Solaris system is a crucial task for system administrators and users alike. RAM plays a vital role in a computer’s performance, affecting the speed and efficiency with which it can process data and run applications. In Solaris, there are several methods to check the RAM size, each providing slightly different information.
One of the simplest ways to check the RAM size in Solaris is to use the ‘prtconf’ command. This command displays detailed information about the system’s hardware configuration, including the amount of physical memory installed. To use ‘prtconf’, simply open a terminal window and type the following command:
prtconf | grep Memory
The output of this command will include a line similar to the following:
Memory size: 16 GB
This line indicates that the system has 16 GB of RAM installed.
Another method of checking the RAM size in Solaris is to use the ‘vmstat’ command. This command provides real-time statistics about the system’s memory usage, including the total amount of physical memory and the amount of memory that is currently being used. To use ‘vmstat’, simply open a terminal window and type the following command:
vmstat
The output of this command will include several lines of information, including the following line:
total memory: 16384 pages = 16 GB
This line indicates that the system has a total of 16 GB of RAM installed.
Knowing how to check the RAM size in Solaris is an important skill for system administrators and users. This information can be used to troubleshoot performance issues, plan for future hardware upgrades, and ensure that the system has sufficient resources to run the applications that are required.

3. grep
The ‘grep’ command is a versatile tool that can be used to filter the output of other commands, such as ‘prtconf’ and ‘vmstat’, to display only the information that is relevant to RAM size. This can be useful when you want to quickly and easily find the RAM size without having to parse through a large amount of output.
For example, to use ‘grep’ to filter the output of ‘prtconf’ to display only the line that contains the RAM size, you would use the following command:
prtconf | grep Memory
This command would produce the following output:
Memory size: 16 GB
Similarly, to use ‘grep’ to filter the output of ‘vmstat’ to display only the line that contains the total amount of physical memory, you would use the following command:
vmstat | grep total memory
This command would produce the following output:
total memory: 16384 pages = 16 GB
By using ‘grep’ to filter the output of other commands, you can quickly and easily find the information that you need without having to parse through a large amount of data. This can be useful for a variety of tasks, including troubleshooting, performance monitoring, and capacity planning.
