careful. it seems to work since you are sitting on it. read further on expand_path...

eg,

irb(main):009:0> puts `pwd`
/home/botp
=> nil
irb(main):010:0> Dir.foreach("/home/botp") do |temp|
irb(main):011:1*    p "#{temp} #{File.expand_path temp}"
irb(main):012:1>    p File.directory? "#{File.expand_path temp}"
irb(main):013:1> end
(irb):12: warning: parenthesize argument(s) for future version
". /home/botp"
true
".. /home"
true
".w3m /home/botp/.w3m"
true
"installer /home/botp/installer"
true
"mbox /home/botp/mbox"
false
"mail /home/botp/mail"
true
....

irb(main):009:0> puts `pwd`
/etc
=> nil
irb(main):010:0> Dir.foreach("/home/botp") do |temp|
irb(main):011:1*    p "#{temp} #{File.expand_path temp}"
irb(main):012:1>    p File.directory? "#{File.expand_path temp}"
irb(main):013:1> end
(irb):12: warning: parenthesize argument(s) for future version
". /etc"
true
".. /"
true
".w3m /etc/.w3m"
false
"installer /etc/installer"
false
"mbox /etc/mbox"
false
"mail /etc/mail"
false

maybe we may want foreach to optionally pass also the path, like so

   Dir.foreach("/home/botp") do |temp,path|
       p File.expand_path(temp,path)
   end

of course, there is Dir.glob :)
