Dec 28, 2021 at 20:48 comment added Arets Paeglis Thank you! That seems to answer more of my questions than I was able to figure out so far. However, I notice that, when running cat test.xml | sed "s/>[+]\([0-9][0-9]*\)<\/value>/>+$(echo \\1)<\/value>/g" (without piping the result to sha1sum), it seems to process the backreference correctly and outputs not the constant string "\\1" but the actual matched values, unmodified. What could be the case here?
