where did the output go?

Posted by jaymzter (jaymzter), 22 February 2008
I have a script that logs me into a system. It then reads in commands from a file on the local disk, and sends it to the remote system.

At this point I need to capture the output of the command to file. In testing, all output is visible on the terminal, but when I set log_file, everything is recorded *except* the output of the command.

Code:
log_file -noappend script.out
load_cmd $runcmd #builds contents of ossi_list below
foreach element $ossi_list {
send -- $element\n
}
log_file #nothing captured..


Any help would be appreciated

Are you sending the commands as a series without expecting a reply?  I suspect that your Tcl program is teminating before the commands are actually completed and so no output has been received back.   A similar thing happens if you start off an FTP get but don;'t expect the nexct prompt - you get an empty file or just the first few bytes as the parent of the runniing process is killed.

Adding an expect for the returned prompt got logging working. Thanks!
