I'm new to RUBY, but am familar with other scripting languages, PHP, 
Perl, Wscript, etc.   I'd like to be able to run items from the shell 
such as ls -l > dirlisting.txt.  Just an example.  Can I do this?

I would have just used the search on these forums, but unfortuantely 
when I click Search I get "The page cannot be found".   Hope they can 
get this fixed so I won't have to ask every little question.

Thanks in advance.
-Greg

Try the Pickaxe book, the first edition is available on-line in pdf 
format.  You can pass commands to the shell directly using back ticks `s 
-l > dirlisting.txt` or the %x expansion %x{echo "me, me, me..."}

Jim

There are two ways. One way:

file_list = `ls -l`.scan(/^.*$/)[1..-1]
file_list.each { |line|
  puts "permissions for #{line[49..-1]} are #{line[1..9]}"
}

The other way:

system('ls -l > dirlisting.txt')

} Thanks in advance.

Thanks for the tips, they work like a charm.  Does anyone know why the 
search functionality doesn't work?

There are plenty of other ways.

system "ls", "-l"
system "bash", "-c", "ls -l > dirlisting.txt"
....
Dir["*"].each {|f| File.symlink? f and puts f}
....
