Quick SLoC counter in CLI

sloc.sh

# Counts source lines of code in current directory. Replace *.java with your source extension.
# (ignores empty lines)

find . -type f -name '*.java' -exec cat {} \; | sed '/^\s*$/d' | wc -l

# to ignore comments (in languages where comments start with #)

find . -type f -name '*.java' -exec cat {} \; | sed '/^\s*#/d;/^\s*$/d' | wc -l

Somebody should create an alias out of this: sloc *.java or sloc *.m, that would be fun!

In my system (Mac OS X 10.7.5), sed doesn't recognize \s as a command, so this doesn't work correctly. Using [ \t] instead seems to solve the issue.

In most package managers (apt, brew etc) there is sloccount package. It gives detailed stats, you better use it.
