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


Required parameters:

-o file - file to write the trace data to Execution control settings:
-t msec - timeout for each run (none)
-m megs - memory limit for child process (75 MB)
-Q - use binary-only instrumentation (QEMU mode)
-U - use Unicorn-based instrumentation (Unicorn mode)
-W - use qemu-based instrumentation with Wine (Wine mode)
(Not necessary, here for consistency with other afl-* tools) Other settings:
-i dir - process all files in this directory, must be combined with -o.
With -C, -o is a file, without -C it must be a directory
and each bitmap will be written there individually.
-C - collect coverage, writes all edges to -o and gives a summary
Must be combined with -i.
-q - sink program's output and don't show messages
-e - show edge coverage only, ignore hit counts
-r - show real tuple values instead of AFL filter values
-c - allow core dumps This tool displays raw tuple data captured by AFL instrumentation. For additional help, consult docs/ Environment variables used: LD_BIND_LAZY: do not set LD_BIND_NOW env var for target AFL_CMIN_CRASHES_ONLY: (cmin_mode) only write tuples for crashing inputs AFL_CMIN_ALLOW_ANY: (cmin_mode) write tuples for crashing inputs also AFL_DEBUG: enable extra developer output AFL_MAP_SIZE: the shared memory size for that target. must be >= the size
the target was compiled for AFL_PRELOAD: LD_PRELOAD / DYLD_INSERT_LIBRARIES settings for target AFL_FORKSRV_INIT_TMOUT: time spent waiting for forkserver during startup (in milliseconds) AFL_QUIET: do not print extra informational output
