sloccount

TLDR

Count lines in directory

$ sloccount [src/]

Count with details

$ sloccount --details [src/]

Duplicate file handling

$ sloccount --duplicates [src/]

Wide output format

$ sloccount --wide [src/]

Add effort estimates

$ sloccount --effort [1.0] [2.5] [src/]

SYNOPSIS

sloccount [options] directories...

sloccount counts physical source lines of code (SLOC) in software projects. It recognizes many programming languages and provides effort and cost estimates using the COCOMO model.
The tool helps measure project size, estimate development effort, and track codebase growth.

PARAMETERS

--details

Show per-file details.

--duplicates

Count duplicate files.

--crossdups

Count cross-directory duplicates.

--wide

Wide output format.

--effort a b

COCOMO effort parameters.

--schedule a b

COCOMO schedule parameters.

--personcost cost

Annual person cost.

--overhead rate

Overhead rate.

--datadir dir

Data directory.

--addlang lang

Add language.

CAVEATS

COCOMO estimates are rough approximations. Language detection may miss some. Large projects slow to analyze. Generated code may skew counts.

HISTORY

SLOCCount was created by David A. Wheeler to accurately count source lines. It applies software economics models to estimate development effort, helping with project planning and comparisons.
