ruby -e and global variables

Show all headers | View raw

I'm trying to assign a global variable when using ruby -e
`ruby -e "$a=3"`
-e:1: syntax error, unexpected '='

So it seems I can't assign global variables when using ruby -e
What I wanted is to assign $stdout = StringIO.new
so I capture the output
