How do you create the list of files to check? You could use "find $DIR -type f" to list regular files only.

Yes. Exactly. The capability you ask for is already present.

One can easily exclude dirs from the source. Either trivially with find, or filtering like: LANG=C xargs -d'\n' -r stat -L -c "%F:%n" < ${ALLFILES} | # decorate sed '/^directory:/d; s/^[^:]*://' | # filter and undecorate xargs -d'\n' md5sum # process cheers, Pádraig.

ALLFILES is indirectly made using find $DIR, but I can't use -type f during that find. The primary usage of that list is to create a tar using --files-from and when a directory is empty, you need to include the directory name directly. > Yes. Exactly. The capability you ask for is already present. > > Please try this: > > find . -type f -exec md5sum {} + > > Replace '.' above with a directory if you wish it to find files in a > different directory. > > Bob This does not work too in my case. I didn't want to calculate md5 for each file found in my chroot. I care only for a shorter list of files to be include in a tar. The only change I find is derived from the slow version, but instead of running md5sum each time, adding true file names to a list that md5sum will only use at the end: rm /tmp/ALLFILES* time (for myfile in ${ALLFILES} | sed -e 's/^dev.*//' -e 's/^sys.*//'); do if [ -f /${myfile} ]; then echo /$myfile >>/tmp/ALLFILES; fi; done; xargs md5sum < /tmp/ALLFILES >/tmp/ALLFILES.md5) real 0m1.967s user 0m1.368s sys 0m0.604s This is approximatly 100% slower than the fast version but does not need hiding errors (from directory message and program status). That's fast enought for my need and divide by 5 the time from the first slow version.

Exactly. The capability you ask for is already present. Do you suppose we can convince GNU grep's maintainer to follow this philosphy? $ mkdir d $ touch d/foo $ grep foo * $ It opens and reads, gets EISDIR, and intentionally skips printing it. Grr.

Too late. GNU grep already has --recursive. I think adding --recursive to grep was a mistake. It then requires most of 'find' to be added to it too. (--include*, --exclude*) > $ mkdir d > $ touch d/foo > $ grep foo * > $ > > It opens and reads, gets EISDIR, and intentionally skips printing it. Grr. All silently. For most cases I think your example would have been a a case of programming error. It would be better to make those cases noisy. The above seems to be a bug since it violates the documented action of 'read' for directories. It appears to be skipping by default. Even when --directories=read is specified. > But wait, there's a -d option with 3 alternatives for what to do with > directories! ...and none of choices is "just print the EISDIR so I'll know > if I accidentally grepped a directory". And the problems just go on and on.
