SLOCCount (pronounced "sloc-count") is a suite of programs for counting physical source lines of code (SLOC) in potentially large software systems (thus, SLOCCount is a "software metrics tool" or "software measurement tool"). SLOCCount can count physical SLOC for a wide number of languages; listed alphabetically, they are: Ada, Assembly, awk, Bourne shell, C, C++, C shell, Expect, Fortran, Java, lex/flex, LISP (including Scheme), Modula3, Objective-C, Pascal, Perl, PHP, Python, sed, TCL, and Yacc. SLOCCount can automatically determine if a file is a source code file or not, and if so, which language it's written in. As a result, you can analyze large systems completely automatically. SLOCCount also includes some report-generating tools to collect the data generated and present it in several different formats.
