How to count the number of lines of code?
You can do it simply by combining a few Linux tools. Suppose you are in a root directory that contains many recursive subdirectories and have Haskell (.hs) source files.
$ find . -name "*.hs" -exec wc \{\} \; | cut -c 1-8 | awk 'BEGIN {sum=0} {sum=sum+$0} END {print sum}'
END.
