This doesn't work, because:
$ printf linkedintrouble | openssl sha1
(stdin)= 3ac85868a20c977661a12f770f0d116f87c74831
The leading '(stdin)=' messes the pattern being fed to 'grep'.
Yes, I've read http://partmaps.org/era/unix/award.html#cat http://partmaps.org/era/unix/award.html#cat . The output of sha1sum already contains a trailing '-' which is something I wanted to feed into 'grep' using command substitution, so that 'grep' can now just accept the input stream from 'stdin'. Now, how do you feed the input to grep via 'stdin' if you don't want to use 'cat'?
- spal 14y agoBTW, the commands involving 'openssl' can be fixed in this manner. $ printf linkedintrouble | openssl sha1 | cut -c10- | grep -f - combo_not.txt 3ac85868a20c977661a12f770f0d116f87c74831
- uselessuseof 14y agodoes your grep have an -f option? printf linkedintrouble |sha1sum |sed 's/ .*//' |grep -f - combo_not.txt
- spal 14y agoIf you look where we started ( http://news.ycombinator.com/item?id=4076559 http://news.ycombinator.com/item?id=4076559 ), I'm not trying to feed the regex pattern to grep via stdin, but I'm trying to feed the input stream to be searched for the pattern to grep via stdin.
