NAME

       afl-cmin

SYNOPSIS

       afl-cmin [ options ] -- /path/to/target_app [ ... ]

OPTIONS

       Required parameters:
         -i dir        - input directory with starting corpus
         -o dir        - output directory for minimized files

       Execution control settings:
         -T tasks      - how many parallel tasks to run (default: 1, all=nproc)
         -f file       - location read by the fuzzed program (stdin)
         -m megs       - memory limit for child process ( MB)
         -t msec       - run time limit for child process (default: 5000)
         -O            - use binary-only instrumentation (FRIDA mode)
         -Q            - use binary-only instrumentation (QEMU mode)
         -U            - use unicorn-based instrumentation (unicorn mode)
         -X            - use Nyx mode

       Minimization settings:
         -A            - allow crashes and timeouts (not recommended)
         -C            - keep crashing inputs, reject everything else
         -e            - solve for edge coverage only, ignore hit counts

       For additional tips, please consult README.md

       Environment variables used:
       AFL_CRASH_EXITCODE: optional child exit code to be interpreted as crash
       AFL_FORKSRV_INIT_TMOUT: time the fuzzer waits for the forkserver to come up
       AFL_KEEP_TRACES: leave the temporary <out_dir>/.traces directory
       AFL_KILL_SIGNAL: Signal delivered to child processes on timeout (default: SIGKILL)
       AFL_FORK_SERVER_KILL_SIGNAL: Signal delivered to fork server processes on
          termination (default: SIGTERM). If this is not set and AFL_KILL_SIGNAL is
          set, this will be set to the same value as AFL_KILL_SIGNAL.
       AFL_NO_FORKSRV: run target via execve instead of using the forkserver
       AFL_CMIN_ALLOW_ANY: write tuples for crashing inputs also
       AFL_PATH: path for the afl-showmap binary if not found anywhere in PATH
       AFL_PRINT_FILENAMES: If set, the filename currently processed will be printed to stdout
       AFL_SKIP_BIN_CHECK: skip afl instrumentation checks for target binary
