If you mean configured interfaces, a simple "ifconfig" shows you all, even
together with virtual
interfaces, or alternatively you can see the configured physical NICs with "cat
/proc/net/dev".
If you mean "total of physically installed interfaces, which may not be
configured",
the answer is more complicated: the initialization of autodetected NICs will
show up in the kernel
bootstrap output (you could get it with "dmesg"). On most bus systems you can
even get NICs which
are not autoconfigured through an attached hardware scan (e.g. "lspci" shows
you all attached hard-
ware on a pci bus). On older bus systems (notably ISA with old non-pnp NICs)
there is often no way
to detect them when they are not configured.
Hope that helps,
