stdin and stdout are just special files for a process. mkfifo makes a special file like this with an arbitrarily name. you can use it for commands that don't support reading from stdin.
it would be something like:
mkfifo apipe
crunch params > apipe && hydra -P apipe
if you want to wait until crunch is done, or
crunch params > apipe & hydra -P apipe
if you want to start processing right away. if you start processing right away, you need a way to make one consume as fast as the other outputs, or gracefully handling bad reads
I want merge (union) output from two different commands, and pipe them to a single command.
A silly example:
Commands I want to merge the output:
cat wordlist.txt
ls ~/folder/*
into:
wc -l
In this example, if wordlist.txt contains 5 lines and 3 files, I want wc -l to return 8.
$cat wordl...
