You've got me in hysterics here referencing Get Smart. I love that series.

I havn't seen any reruns lately though.

There is an unzipped Packages file on debian-multimendia mirror I am using, so I use that instead. (This is the purpose of the "|grep -v z" in script.)

but, That only tells you how long it takes to iterate through the loop to get to the gzip command, not how much time is spent in each statement.

smth like:

while read inputline
do echo "input line is " $inputline

      search=3D`grep...`
      echo "search is " $search"
      if...
	echo "we got a good search"
      fi
      ...

done

so that you can see how long is actually spent on the creation of a value for $search, who long in the if comparison and so forth. You stated above that the slowdown is in the "search=3D" lines, and I'm curious to know how you determined that. =20

or did you do

time search=3D`grep...`

which could give meaningful output too.

=2E..

sorry, i meant replacing the whole operation with awk which, while a little heavy might be a better solution than instantiating a whole bunch of greps and cuts over and over. but that's just a guess. and your solution should certainly work pretty easily. and i see nothing that would cause it to take a full second per iteration. my brief testing (granted a much more powerful system) scrolled the output right by... faster than I could hope to read. There was definitely no noticeable delay anywhere in the process.

no. we feed the mails send to reportspam to the db manualy, so that can't happen.

I have a V1456VQH-X pnp ISA card that I only use for sending and receiving faxes. It worked in Sarge but I have not been able to get it to work in my Lenny/Sid box. I reinstalled sarge on a different partition and the modem still works so it is not a hardware issue. I believe it is a kernel issue since it works with kernel2.4 and not with kernel 2.6. Although it works in 2.4 (sarge) I have not been able to find any log messages or dmesg output to tell me exactly what the kernel is doing iwth it. All I know is that minicom with /dev/ttyS1 returns OK when I type AT. I also went to an old partition with etch i(2.6.2.6.18-3-k7 #1 SMP Mon Dec 4 17:23:11 UTC 2006 i686 GNU/Linux) and it also doesn't seem to work. dmsg returns the following:
> isapnp: Scanning for PnP cards...
> isapnp: Card '56K PnP DATA FAX VOICE Modem'
> isapnp: 1 Plug & Play card detected total
> So it does seem like the kernel finds it. When I go to /sys/devices/pnp1/01:01/name I find "56K PnP DATA FAX VOICE Modem" and the file /sys/devices/pnp1/01:01/01:01.00/resources has "state = disabled" After "echo AUTO > resources" the file resources contains: state = disabled io 0x2e8-0x2ef irq 5 When I try running scanModem from linuxant it tells me that I need some proprietary driver from them but, as I said, the card worked in sarge. I don't know whether there was a decision to stop supporting some devices or this is a bug or I am just not configuring things right. (If it is a configuration issue that would also indicate a documentation bug.) I would like to post a bug but am not sure to which package it would go. I guess to the linux-image2.6 package. Any guidance would be appreciated.
