Finding the glibc version

[WitchCraft]

How to find out which version of glibc is running on your machine:

Go to console and type:

/lib/libc.so.6

You will get:

all:~# /lib/libc.so.6
GNU C Library (EGLIBC) stable release version 2.9, by Roland McGrath et al.

all:~#

Or you can do it via the package-managers:

On Debian:

sudo aptitude show libc6

or

sudo apt-cache show libc6

And on RedHat/Fedora:

rpm -q glibc

which should output something like

glibc-2.3.3-27.1
