Re: Re: Re: Re: reading output from another script

good idea with the autoflush idea, however it doesnt appear to fix it. Here are my findings:
I have a test program that dumps look-alike output to the screen for development of this script...I call it test...so I do a
./test |./monitor.pl
For testing I have it dump 9 lines, sleep for a second, then dump 9 more, and so on...when I run it through the monitor script, about every 5 seconds it dumps a big chunk to the screen. if I reduce it to dump 1 line, sleep for 1..then it takes longer...not exact numbers here, but it looks like it dumps the same number of lines in big chunks, just it takes longer to do...prob about 30 seconds or so...I changed it to dump 1 line and then sleep for 10, and guess what....the monitor script is now taking FOREVER to dump anything....if it was just a matter of the screen not being able to catch up with it, I could understand, but why, if the perl script is handling it in real time, would it take so long for the print to come out?
Its no big thing, the script they wanted me to monitor dumps so fast that it proccesses the chunk in about 5 seconds or so, so I dont NEED to have this riddle solved for me, but it is a big stumper for me and if anyone knows the answer to this new problem that would be cool ;)
