Hi all, I'd like to request a new --pipeout feature for shaXXXsum to allow on-the-fly checking of files. It should be possible to request shaXXXsum to pass stdin data to stdout.
I'd like to do s.th. like this to avoid reading files twice from network or storing them locally: $ set -o pipefail $ cat network_path/big.img.gz | sha256sum --pipeout -c cs.sha256 | gzip -d | dd of=/dev/sdx --pipeout should imply --quiet of course and just return nonzero on fails. It did a test implmentation for sha256 case. Seems this can be implemented easily. Maybe my implementation is not bullet proof however. Questions to the maintainers: . Is such a feature desirable/acceptable? . If so, can --pipeout be used or should there be a better option name? . Should there be a single letter option?
