rip calendar attachments from an email (in ruby)

See here for context.

I did this for undees

#!/usr/local/bin/ruby
$: << '/home/username/usr/local/lib/ruby/site_ruby/1.8'
require 'tmail'

s = $stdin.read
mail = TMail::Mail.parse s
mail.parts.each do |part|
  if 'text/calendar' == part.content_type
    t = part.body
    t.gsub!(/=[\r\n]+/, '')
    t.gsub!(/=(\w\w)/) {$1.hex.chr}
    
    outPath = '/home/username/path/to/Calendar.ics'
    File.open outPath, 'w' do |f|
      f.write t
    end
    File.chmod 0664, outPath    
  end
end
to email ruby calendar by jason on May 29, 2005

Clearing out a bunch of spam with spoofed emails that were bounced back to some poor guy with a catchall email

We don't really want to delete them all just in case.

cd /usr/local/scratch/
mkdir junk
find /var/spool/postfix -exec grep "somediscernible-feature.com" '{}' \; | awk '{print($3)}' | xargs -J X mv X ./junk/


The "find" produces

Binary file /var/spool/postfix/active/D/D8832E38 matches
Binary file /var/spool/postfix/active/D/D78EC1C72 matches
Binary file /var/spool/postfix/active/D/D593D279D matches
Binary file /var/spool/postfix/active/D/D0EB32833 matches


The awk

/var/spool/postfix/active/D/D8832E38
/var/spool/postfix/active/D/D78EC1C72
/var/spool/postfix/active/D/D593D279D
/var/spool/postfix/active/D/D0EB32833


And then the mv, moves it.
