how many lines of source in linux now?

cd /usr/src/linux 

2.4.17 kernel

find . -name *.[c,h] | xargs wc -l | grep total > /tmp/totallines.txt

Not sure why multiple totals, but

produces:

 368651 total
  93937 total
  92969 total
  60153 total
 103396 total
  54820 total
 584749 total
 559389 total
 533140 total
 527104 total
 330005 total
 201343 total
 209730 total

so maybe 3.5 million lines in entire linux kernel

15k lines for /usr/src/linux/kernel
200k for net
278k for fs
400k include  (machine arch. specific in here too)
500k for arch
2 million lines for drivers

bulk of kernel is arch + drivers

note:
	multiple archs well supported; e.g., sparc, arm, x86, mips, alpha
