Question

On a bash console, if I do this:

cd mydir
ls -l > mydir.txt

The > operator captures the standard input and redirects it to a file; so I get the listing of files in mydir.txt instead of in the standard output.

Is there any way to do something similar on the rails console?

I’ve got a ruby statement that generates lots of prints (~8k lines) and I’d like to be able to see it completely, but the console only “remembers” the last 1024 lines or so. So I thought about redirecting to a file – If anyone knows a better option, I’m all ears.

You can use override $stdout to redirect the console output:

$stdout = File.new('console.out', 'w')

You may also need to call this once:

$stdout.sync = true

To restore:

$stdout = STDOUT
