Final answer:
To check the library version on a Linux system, use package management commands such as dpkg or rpm for system libraries, pip show for Python libraries, or ldconfig -p to list shared libraries. Specific library version information can sometimes be found using the --version flag on the executable library file.
Step-by-step explanation:
To check the library version on a Linux system, you can use various commands depending on the type of library you're dealing with. For system libraries or libraries installed through a package manager, you can typically use dpkg -l on Debian-based systems or rpm -q on RPM-based systems to check installed libraries and their versions. If you're working with a language-specific library, like a Python library, you would use that language's package manager, such as pip show library_name for Python.
When it comes to shared libraries, a common command is ldconfig -p to list all the shared libraries available on the system. To find the version of a specific shared library, you could use the ldconfig -p | grep library_name command. Sometimes, libraries also provide version information when using --version or -version flags directly on the executable library file.
