Redirect hardcoded program output to stdout?

Question

I'm using a program called "prodigal" that does not output to stdout - instead you have to specify an output like so:

prodigal -o outfile.txt

Instead of going to a specific file I'd like to go stdout - is there a simple way to do this?

So something like this:

prodigal -o > stdout

Thanks!

Your file system may have an entry for the current process's standard output.

prodigal -o /dev/stdout

/dev/stdout is often a link to an operating-system-specific file, such as /dev/fd/1 or /proc/self/fd/1. I suspect that most Linux distributions will have /dev/stdout, or at the very least /proc/self/fd/1.

Sorry, I owe an upvote to you, since my daily limit got exhausted. I will release this upvote tomorrow morning.

/dev/stdout is only treated specially when bash opens it, such as in redirections. Passing /dev/stdout to a command requires that there is a file system entry.
