Automatic Shutdown

Name: Anonymous 2008-04-26 6:53

I need to find a way to shut down my Linux PC (Ubuntu 8.04 Server) after it has up & downloaded 100MB.
Anyone has any idea on how to do this?

if [ $RX -ge 104857600 -o $TX -ge 104857600 ]
then
    init 0
fi


Put it in root's crontab.

Use shutdown -h now.

Ok, thanks.

However if that's the case on a particular system, chances are that the output of ifconfig is also quite different, which breaks the grep/sed stuff as well.

EMACS question: how the hell do I set faces? Say I've been provided with a hl-line-face, how to set it to "red"? (setq 'hl-line-face "red") gives me a type error.

This was not meant as a working script for you to kopipe but rather an idea how to do it and some hints on how to build your own script.

Ok, I currently have this:

#!/bin/bash
RX=`ifconfig eth0 | grep "RX bytes" | sed -e "s/\s*RX bytes:\([0-9]*\).*/\1/g"`
TX=`ifconfig eth0 | grep "TX bytes" | sed -e "s/.*TX bytes:\([0-9]*\).*/\1/g"`
echo $RX
echo $TX

When I try this:
Total=$RX+$TX
echo $Total

It gives me this error:
: command not found4: [Here is the $RX]

So I need to change the variable to an integer, can someone please tell me how to do this?

Works for me, just pasted into terminal. Something's out of date with your system if $((...)) doesn't work for arithmetic.

opteron:~ # RX=`ifconfig eth0 | grep "RX bytes" | sed -e "s/\s*RX bytes:\([0-9]*\).*/\1/g"`
opteron:~ # TX=`ifconfig eth0 | grep "TX bytes" | sed -e "s/.*TX bytes:\([0-9]*\).*/\1/g"`
opteron:~ # echo RX: $RX
RX: 35568898031
opteron:~ # echo TX: $TX
TX: 32304412269
opteron:~ # Total=$(($RX + $TX))
opteron:~ # echo Total: $Total
Total: 67873310300

Now that I think about it, it make be putting a double quotes on your RX and TX variables. This may not show up when calling echo since it removes double quotes. However, $((...)) probably can't deal with quoted numbers.

Change
echo RX: $RX
to
set | grep RX
and similarly for TX, then tell us the output.

When I was a kid, I contrived an ingenious contraption with Lego TECHNIC. Using the basic motor, it converted the rotation into repeated up and down thrust that was applied to the `A' button on the Game Boy ADVANCE, which happened to be bound to the procedure swing-whip in the Castlevania game. Making use of my bogus ploy, I could banish multitudes of undead every night and earn experience with little or none effort.

Anyway, OP, I suggest doing something like that.
