freezing output Posted by erickio (erickio), 27 December 2004 I have a tcl/expect script that sends a "show ip route" command to a router. The output that is displayed from this command is around 800 to 100 lines. I don't understand what the source of the problem would be, but about half the time while the screen is displaying the output, my script freezes, and doesn't start again. I don't know if this is an issue with the size of the buffer being too small, or what else it could be. if you need any code examples i can show. tiaPosted by admin (Graham Ellis), 27 December 2004 Potentially a timing problem or something - use log_user to trace the output and see where it hangs.Yes - a code sameple would help - otherwise we're guessing - see the "posting FAQ" at http://www.wellho.net/forum/Assistance/Posting-FAQ.html Posted by erickio (erickio), 27 December 2004 instead of using log_user to trace the output i used it to mask the output. and it seems to work fine now (im getting a diff problem now), but in terms of hanging while displaying the information, my script works. i think the reason it was hanging is that too much information was being displayed and it was making my script crash.------ #sid is the spawn_id #shop is the show command output global sid shop set shop "" send -i $sid "show ip route\n" expect { -i $sid "*\n" {append shop $expect_out(buffer) exp_continue } -i $sid "#" {} } send -i $sid "exit\n" This page is a thread posted to the opentalk forum
