dd has other drawbacks, from printing a status summary that is completely useless in this case to the fact that it controls the block size in a way that might not be what we want. Tu perform a redirection and only a redirection with root privileges, there is the execline infrastructure: sudo /usr/lib/execline/bin/redirfd -w 1 /output/file cat See https://skarnet.org/software/execline/redirfd.html for details.
