md5deep -jn flag #378

Closed stanley3384 closed 6 years ago

Please take a look at my terminal experiments.  After a bit of

experimenting I changed the flags "rwXj4" to "-j4 -r -w -X". Putting the flags in a different order also failed "-r -w -X -j4". I'm running md5deep version 4.2. I'm only reporting this to you as I'm not sure if it's normal or a wee bit un-Linux/UNIX. Regards Ian.

md5deep -trj4 My_Education > hash

md5deep -j4 -r -w -X hash My_Education 3d74b19e05b8894061ad0e99218f1f74 /home/stan/My_Education/gcc/SDL/SDL_DisplayBitmap/image.bmp does NOT match // As expected, md5 sum tampered

md5deep -rwXj4 hash My_Education md5deep: j4: No such file or directory md5deep: Unable to load any matching files. Try md5deep -h for more information. // Failed, not expected

It took me a minute, but I figured out what's going on here. The -X flag requires a filename immediately following the argument. In the order you have them:

$ md5deep -rwXj4

the system is attempting to use j4 as the filename for the -X argument; hence the error you see "j4: No such file or directory." Any of these variations should work:

$ md5deep -j4 -wrX hash My_Education $ md5deep -wrXhash -j4 My_Education
