The GNU C Library (glibc) is a collection of standard C library functions used by many applications on Linux and other Unix-like systems. The glibc version is important because it can affect the compatibility of applications with the system and with each other. Checking the glibc version can be useful for troubleshooting problems with applications or for ensuring that a system is up to date.
There are several ways to check the glibc version on a Linux system. One common way is to use the `ldd` command, which prints information about the shared libraries that are required by a program. To use `ldd` to check the glibc version, run the following command:
ldd --version
This will print the version of glibc that is installed on the system. Another way to check the glibc version is to use the `getconf` command, which prints the value of a configuration variable. To use `getconf` to check the glibc version, run the following command:
getconf GNU_LIBC_VERSION
This will print the version of glibc that is used by the system’s C compiler.
