hi guys,  
I’ve got issue with following:  
#########################################################  
begin

```
t.cmd('String' => "echo -e '#{buffer}' > #{data['cfgwlan']}.tmp",

```

‘Timeout’ =\> 10, ‘Match’ =\> “#{data[‘match’]}”)

rescue TimeoutError, Timeout::Error =\> e  
myLogger.error("#{ **FILE** } #{ **LINE** } Exception:  
#{e.backtrace.join()}")  
end #begin  
#########################################################  
buffer - is a string  
data[‘cfgwlan’] - is file path with file\_name  
t - is telnet object and works correctly with other commands.

But in this case t.cmd causes Timeout::Error exception all the time but  
data[‘cfgwlan’] is each time is overwritten correctly. Looks like that  
after  
echo -e ‘#{buffer}’ \> #{data[‘cfgwlan’]}.tmp none of prompt has been  
appearing and the command ends on timeout.

What is wrong with it?

Any help would be helpful.  
Thanks in advance.  
MT

buffer=“$( sleep 20 )”

are things in buffer complex enough to cause that kind of problem?  
You really need to tell us what is in buffer when it blocks I am afraid.

My stupid fault. In place of “#{data[‘match’]}”… should be Regexp  
object not string. This is why it didn’t work. Now it is ok.
