Hi Ruby folks!

Any ideas? Output and error is below at OUT
Also I am fairly new to Ruby…coming from Perl, so what does the
w_f.sync do?
thank u!

#!/usr/bin/env ruby -w

require ‘pty’
require ‘expect’

DN = “/usr/local/bmc/controlm/ctmagt/ctm/scripts/shut-ag”
UP = “/usr/local/bmc/controlm/ctmagt/ctm/scripts/start-ag”

STDOUT.sync = true
STDERR.sync = true
$expect_verbose = true
prompt_pat = %r/^\sEnter CONTROL-M.*/m

if ARGV.empty?
$stderr.puts “A argument of -stop or -start is required, bye!”
exit 1
end

if ARGV[0] == ‘-stop’
Dir.chdir("/usr/local/bmc/controlm/ctmagt/ctm/scripts")
puts Dir.pwd
puts “\nNow shutting down controlM, please wait…\n”
PTY.spawn("#{DN}") do |w_f|
w_f.sync = true
w_f.expect(prompt_pat){ w_f.puts “ctmagt” }
w_f.expect(prompt_pat){ w_f.puts “ALL” }
end
end

OUT

ruby cntrlM_recycle.rbx -stop

/usr/local/bmc/controlm/ctmagt/ctm/scripts

Now shutting down controlM, please wait…

What platform are you on - operating system type and version, ruby type
and version?

w_f.sync do?

same as autoflush() in Perl

I even tried the passwd command code copied from this site in someone
else’s post and I get a similar error:

ruby -d cntrlM_recycle.rbx

Then it looks like the PTY library doesn’t work properly under HP-UX. If
you can make a small test case which works under Linux but fails under
HP-UX, then you can take it to ruby-core or redmine.ruby-lang.org
