Extracting glibc info in #Linux to see if is greater or equal with 2.7

Related to previous announcement:If you are on ubuntu and your ubuntu release is greater than Hardy (8.04) you are safe , on other distributions you can determine this way the glibc version
You must run the /lib/libc.so.6 and it will return the glibc version
in the first row.
In ubuntu or any debian based distro

/lib/libc.so.6 | head -n 1
GNU C Library (Ubuntu EGLIBC 2.13-0ubuntu1) stable release version
2.13, by Roland McGrath et al.

in this case glibc is 2.13
and is builded from eglibc sources

another option is dpkg interrogation

dpkg -l libc6

on rpm based distros

rpm -q glibc

ps: other alternative ways
