Hello,

i am logging the output from the console to a file. it is giving some strange output in the logged file.

Code:

set fh [open log.txt w+]

while  $running {
           expect {
                  "\n" { puts -nonewline $fh $expect_out(buffer)
                          set h $expect_out(buffer)
                          flush $fh }
                          flush (stdout)
                          -re "->" { break }
                  eof {set running 0}
                  timeout {set running 0}
                  }
         }
close $fh

Console output:

Q: Can you tell me as to why i am getting a newline after 8: ?

Does the environment variable shown in line 8 have a \r on the end of it

I dont think so there is a \r

Sorry - I don't follow that.   The first half of your reply says "no" and the second half says "yes" to me.

Have a look at the outputs through "od -x" or "od -c" and see what characters you've actually got.

I am sorry but can you tell me as to how i should use this. Working on the windows platform.

Either FTP the output across to a Linux of Unix system, or use Cygwin.  You could also use an editor that shows you control codes, or have your Tcl script decode the bytes.  Plenty of choices!
