Linux – Find out library version

linuxUbuntuversion

I want to find out what version of a C library is installed in my system (Ubuntu 12.04). In particular, I'm interested in libnuma. What is the proper way to do it?

cd /usr/lib
ls -l libnuma*
-rw-r--r-- 1 root root 70312 Feb  8  2012 libnuma.a
lrwxrwxrwx 1 root root    12 Feb  8  2012 libnuma.so -> libnuma.so.1
-rw-r--r-- 1 root root 43976 Feb  8  2012 libnuma.so.1

Best Answer

I would use dpkg -l | grep libnuma1 to get the version.

As an example, I have ran dpkg -l on xterm and you can see that I'm running versoin 278-4 of xterm.

# dpkg -l | grep xterm
