Question

I have a wired problem. I tried to concatenate two strings. If I do this with @Client.ip I get a string with a new line. @Client.ip is a string.

I used this:

order= "net rpc shutdown #{ip} --user=administrator%***! --timeout=100 --force -C 'bla'"

or this

order= "net rpc shutdown "+ @client.ip + " --user=administrator%*** --timeout=100 --force -C 'bla'"

The result is this:

net rpc shutdown 178.213.111.69
  --user=administrator%*** --timeout=100 --force -C 'bla'

If I write the ip manually and concatenate it then, it works fine and everything is in one line …. Why is that happening? Has someone an idea? 🙂 I need this string in one line to use the system(-) command.

It sounds like @client.ip has a newline at the end of it. Try striping it out

order= "net rpc shutdown #{@client.ip.rstrip} --user=administrator%*** --timeout=100 --force -C 'bla'"

String#rstrip will remove any whitespace at the end of the string.
