Speaking of pipes, what would be a good way to branch pipes for some work and then join them back again in order? Running: ls | pee "./cruncher" "./muncher" will produce output from both ./cruncher and ./muncher in a mixed order. But often it would be more useful to synchronize the output so that all of ./cruncher output comes first and then ./muncher output. You could redirect ./cruncher and ./muncher output to individual named pipes and then pipe a 'cat cruncherpipe muncherpipe' to follow that: mkfifo cout mout ls | pee "./cruncher >cout" "./muncher >mout" | cat cout mout But that requires the manual precreation of the named pipes which isn't very clean. Using <(./cruncher) on the command line would automatically create an output pipe but doesn't allow redirecting the pipeline to each of the subcommands. Any brilliant ideas?
