Say I have too programs a and b that I can run with ./a and ./b.
Is it possible to diff their outputs without first writing to temporary files?

Use
<(command)to pass one command’s output to another program as if it were a file name. Bash pipes the program’s output to a pipe and passes a file name like/dev/fd/63to the outer command.Similarly you can use
>(command)if you want to pipe something into a command.This is called “Process Substitution” in Bash’s man page.
