Ruby Question
rails - Redirecting console output to a file
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.txtIs 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.
Answer
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
This will redirect all output to the file. If you want to temporarily redirect the output make sure that you store the original value of $stdout so you can change it back.
