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 (default: 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
