# afl-cmin(1)

corpus minimization tool for American Fuzzy Lop (afl)

## NAME

**afl-cmin** - corpus minimization tool for American Fuzzy Lop (afl)

## SYNOPSIS

**afl-cmin** \[options\] -- */path/to/fuzzed/app* \[params\]

## DESCRIPTION

**afl-cmin** tries to find the smallest subset of files in the input directory that still trigger the full range of instrumentation data points seen in the starting corpus.

If a large corpus of data is available for screening, **afl-cmin** can be used to reject redundant files, ideally, with an aggressive timeout (set by **-t**).

Note that the tool doesn't modify the files themselves. For that, you want **afl-tmin**.

## OPTIONS

Run **afl-cmin** without any arguments to see a complete list of options.
