Sample command line

cfv -C -t sha1 -rr -v -L -f checksum.sha1
  • -C
    • Create (as opposed to test)
  • -t sha1
    • Type to create: sha1
  • -rr
    • "Recursive mode 2. In create mode make a single file with deep listing in it. Both recursive modes are equivilant for test mode." As opposed to creating a separate file for each subdir, with -r.
  • -v
    • Verbose (maybe remove and replace with a quiet option)
  • -L
    • "Don't follow directory symlinks in recursive mode." Because there shouldn't be any, and I don't want to follow even if there are.
  • -f checksum.sha1
    • Output filename to create.

Validateable with cfv, of course, and...

sha1sum -c checksum.sha1

(tested the single file deep recursive mode)

cfv has died with python2.7. So this seems to be the way to do it natively with sha1sum...

shopt -s globstar && sha1sum -b ** > checksum.sha1
