adding `--exclude` option? about rhash HOT 8 CLOSED

Does the --accept option is really not enough? I need a reason to add the feature.

Also some things shall be resolved.

1. The --exclude option can be implimented like --accept in very dumb way - it will take a list of comma delimited file suffixes (extensions). RHash currently doesn't supports file masks or regex'es for simplicity and portability reasons.
2. If a user specify both --accept and --exlude options than the exlude should apply after accept.
3. RHash has separate --accept-crc option for the --check mode, so it look that somebody will ask for an --exclude-crc.

@rhash I have an unknown number of files/folders to traverse and they are outside of my control on how they were updated, but I do have only 1 file that I know for sure that I want to exclude. So I think there's a valid use case for it.

Ok, it's a good reason. I've put the feature request into the todo list.

Just to note, it's better to ask for features on the sourceforge project page to keep them in one place.

The --exclude option is now supported in Rhash v1.3.3.

@rhash thanks man, will test it out!

I just tested this and it works in v1.3.3, but it's not in the --help yet, just a friendly tip:

$ rhash --version && rhash --help |grep ex
RHash v1.3.3
  -V, --version Print program version and exit.

Is there any way to get --exclude to allow excluding listed directories? When hashing in recursive mode sometimes there may be certain time-consuming but irrelevant subdirectories you'd like to ignore. Thanks.

@newhoa the --exclude option works only for files, for excluding directories you should apply shell script magic using find/grep/xargs e.t.c.
