How to suppress Rails console/irb outputs

I was testing some DB entries in our production server in Rails Console where almost all the commands were producing a huge number of lines of output and causing the ssh channel to hang.

Is there a way to suppress the console/irb screenfuls?

Solution 1:

You can append ; nil to your statements.

Example:

users = User.all; nil

irb prints the return value of the last executed statement; thus in this case it'll print only nil since nil is the last executed valid statement.

Solution 2:

In search of a solution how to silence the irb/console output, I also found an answer at austinruby.com:

silence irb:

conf.return_format = ""

default output:

conf.return_format = "=> %s\n"

limit to eg 512 chars:

conf.return_format = "=> limited output\n %.512s\n"
