Quick sed replacemnt

[yitzhakbg]

I need a quicky which I can't do in sed and I did it very clumsily.
I need to filter the following file, changing the class name's first
letter to upper case.
For example, rewrite the file with the word "organizationsController"
changed to "OrganizationsController".
Thanks.

Here's a sample file:

#
# A skeletal controller
#
class organizationsController < ApplicationController
active_scaffold rganization
# layout "activescaffold"
end

Sorry, You didn't understand. The class name can be anything. Whatever
it is, I want the first changed to upper case. If you can show me how
to do it in Sed, that's fine. I found it messy and tried writing a
Ruby script. It also came out a little messy. Can you help me?

Take your pick:

class String
def upcase_first_letter_1
new_str = self.dup
new_str[ 0 ] = new_str[ 0..0 ].upcase
new_str
end
def upcase_first_letter_2
self.sub( /./ ){ |c| c.upcase }
end
def upcase_first_letter_3
self.sub( /[a-z]/i ){ |c| c.upcase }
end
end

%w| orgController _orgController |.each{ |n|
p n.upcase_first_letter_1,
n.upcase_first_letter_2,
n.upcase_first_letter_3
}
#=> "OrgController"
#=> "OrgController"
#=> "OrgController"
#=> "_orgController"
#=> "_orgController"
#=> "_OrgController"

Thank you, but you still didn't get it. organizationscontroller is
only an example. It could be anything else

perl -pi -e 's/^class ([a-z])/"class ".uc($1)/ge' filename.rb

works.. there is a nicer way to do the upper casing in a Perl s// but
I forget what, but this works ;-)

I remembered the nicer way to do it

perl -pi -e 's/^class ([a-z])/class \u\1/g' filename.rb

ruby -pe 'gsub(/organizationsController/){|x|x.capitalize}'
ruby -pe 'gsub(/\borganizationsController\b/){|x|x.capitalize}'

__Sorry__! String#capitalize will destroy the camel case
spelling.

Here's another one:

ruby -i -pe 'gsub(/\bo(?=rganizationsController\b)/){|x|x.upcase}'
