Ruby string escape characters

Question

I want to get the quoted string in the line below into a string exactly as-is, but I am tripping on the necessary escape sequences for Ruby. mycommand.cmd is really a wrapper for powershell.exe so I want to preserve everything between the quotes, and hold onto the escape characters that are already there.

mycommand.cmd "^|foreach-object { \"{0}=={1}\" -f $_.Name, $_.Found }"

Answer 1

Use single quotes :

ruby-1.9.3-p0 :001 > '^|foreach-object { \"{0}=={1}\" -f $.Name, $.Found }'
 => "^|foreach-object { \\\"{0}=={1}\\\" -f $.Name, $.Found }" 

The only escape characters in single quotes are : \\' and \\\\
