1. May i know, other than C language, is there any other programming language is/are used inside Linux Kernel?!?! is there any c++, Perl, python programs are used for peculiar tasks inside Linux Kernel?!?!
Well, let's find out ? If you open up a shell/terminal and change into the top level directory of your Linux kernel source and run the command below:
find . -type f -and -printf "%f\n" | grep -io '\.[^.]*$' | sort | uniq -c | sort -rn ( Breaking this down, find all files+get the filename+pull out the file extension+sort+only keep unique ext+sort with a stats count)
For that I recommend a tool called sloccount [1]...
BTW, running it now against Linux Kernel source I got:
Totals grouped by language (dominant language first): ansic: 16675070 (97.83%) asm: 294179 (1.73%) perl: 26346 (0.15%) sh: 18781 (0.11%) python: 15642 (0.09%) cpp: 6512 (0.04%) yacc: 4586 (0.03%) lex: 2479 (0.01%) awk: 1387 (0.01%) pascal: 231 (0.00%) sed: 5 (0.00%) Total Physical Source Lines of Code (SLOC) = 17,045,218
'tokei' is _much_ faster when dealing with large code bases than sloccount. And gives a bit different view of the tree as well, I'd recommend it over sloccount these days. thanks, greg k-h
