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 -- Posted via http://www.ruby-forum.com/.

You can pass commands to the shell directly using back ticks `s -l > dirlisting.txt` or the %x expansion %x{echo "me, me, me..."} Regards, Jim -- Posted via http://www.ruby-forum.com/.

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. } -Greg --Greg
Thanks for the tips, they work like a charm. Does anyone know why the search functionality doesn't work? -- Posted via http://www.ruby-forum.com/.

Dir["*"].each {|f| File.symlink? f and puts f} .... Cheers robert
