Solaris is a discontinued UNIX operating system developed by Sun Microsystems. It was first released in 1992 and was the primary operating system for Sun’s SPARC workstations and servers. Solaris was also ported to x86-based systems in 2005.
There are several ways to check the version of Solaris that is installed on a system. One way is to use the uname command. The uname command prints information about the system’s hardware and software, including the operating system version.
$ uname -vSunOS 5.10 Generic_142900-29 sun4u sparc SUNW,Ultra-250
Another way to check the version of Solaris is to use the head command to display the first few lines of the `/etc/release` file. The `/etc/release` file contains information about the operating system version, as well as the system’s hostname and IP address.
$ head /etc/releaseSolaris 10 10/09 s10x_u9wos_09 Copyright (c) 1983-2010 Oracle and/or its affiliates. All rights reserved.
The version of Solaris that is installed on a system can also be found in the system’s firmware. To access the firmware, you will need to reboot the system and press the appropriate key to enter the firmware settings.

2. /etc/release file
The /etc/release file is a crucial component of Solaris systems, providing valuable information about the installed Solaris version, system hostname, and IP address. Understanding the connection between the /etc/release file and “how to check the version of Solaris” is essential for effective system management and maintenance.
-
Facet 1: System Identification
The /etc/release file serves as a primary source of system identification. It contains a concise yet informative description of the Solaris version installed on the system, including the major and minor version numbers, as well as any additional release information. This information is critical for system administrators to identify the specific Solaris version running on their systems, which is essential for tasks such as software compatibility checks, security patch management, and troubleshooting.
-
Facet 2: Hostname and IP Address Lookup
In addition to Solaris version information, the /etc/release file also contains the system’s hostname and IP address. The hostname is a unique identifier assigned to the system within a network, while the IP address is the numerical representation of the system’s network location. Having this information readily available in the /etc/release file simplifies system identification and network configuration tasks for administrators.
-
Facet 3: Version Verification
The /etc/release file acts as a reliable source for verifying the Solaris version installed on a system. Unlike the uname command, which provides general system information, the /etc/release file specifically focuses on Solaris version details, making it an ideal reference for system administrators to confirm the exact version of Solaris running on their systems. This is particularly useful in scenarios where multiple Solaris versions may be deployed across an organization, and accurate version identification is crucial for maintaining consistency and compatibility.
-
Facet 4: Historical Record
The /etc/release file serves as a historical record of the Solaris version installed on a system. By examining the /etc/release file, system administrators can trace the evolution of Solaris versions on a particular system, including any upgrades or downgrades that may have occurred over time. This information can be valuable for auditing purposes, system documentation, and understanding the system’s configuration history.
In summary, the /etc/release file plays a vital role in “how to check the version of Solaris” by providing detailed and reliable information about the Solaris version, system hostname, and IP address. Understanding the facets of the /etc/release file empowers system administrators with the knowledge necessary for effective system management, maintenance, and troubleshooting.
3. Firmware
The system firmware is a crucial component in understanding “how to check the version of Solaris.” Firmware, also known as BIOS (Basic Input/Output System), is responsible for initializing and configuring the system hardware during the boot process. It contains essential information about the system, including the version of Solaris installed.
Accessing the firmware to check the Solaris version is particularly useful in situations where the operating system is not accessible or corrupted. By entering the firmware settings during system startup, administrators can view the Solaris version, along with other hardware and configuration details. This information can be vital for troubleshooting boot issues, hardware compatibility, and system recovery.
To access the firmware, the specific key or key combination depends on the system manufacturer and model. Common keys used to enter the firmware settings include F2, F10, F12, or DEL. Once in the firmware settings, administrators can navigate to the appropriate section to find the Solaris version information.
In summary, understanding the connection between the system’s firmware and “how to check the version of Solaris” provides administrators with an alternative method to obtain the Solaris version, especially when the operating system is inaccessible. This knowledge is essential for system maintenance, troubleshooting, and ensuring the system is running the intended version of Solaris.
