Ask Ubuntu General Room

See, I am not asking for others to help me with self control actively. i only ask in extreme cases. and yes, terdon is right - if customer wants it, give it to them. Worst case is that they won't come back. I,however, will. And i don't hold grudges

Journeyman Geek

@Serg it goes against what suspensions are for tho

terdon

@Serg Actually, if we're being serious, I wouldn't suspend someone if they only wanted to get suspended to stop spending too much time here. I'd just tell them to grow up.

I don't want to have to go through the various clicks needed to suspend someone just because they can't manage to turn off their computer.

Serg

@JourneymanGeek yes, i know. I had this discussion with Oli before

@terdon it's a bit more complicated than just turning off computer

but anyhow . . .

this needs a kick askubuntu.com/q/827807/295286

If you don't want to come here, stop coming here. I admit that I would prefer you kept coming here so we can enjoy your great contributions, but if you don't have the time, stop doing it.

Serg

I enjoy coming here, in all honesty.

Like i said, it's a combination of things, plus fallout from previous days

one thing for sure: today will be interesting. I'll see how well i know this material. Today I've an exam im control systems

D&A communication will be a problem, but I'll survive, not the first time

And luckly we're doing a lab today in datacomm class. so yay, more wireshark

i might start doing wireshark questions soon too

Journeyman Geek

heh. I leave my PC on all day, and just respond to pings ;p

Seth

@edwinksl just installed it!

jokerdino

me too

Serg

wishbi was living close to campus. commuting every damn morning is painful sometimes

Seth

1:11 PM

Me too just installed it or me too leaves my computer on?

Serg

all of the above

jokerdino

@Seth both

I installed Alo.

Seth

Cool! Let me try to add you..

Well that's lame. Looks like you can only add people by phone number?

jokerdino

Yes

Seth

That will make this a lot less used...

jokerdino

1:20 PM

Also yes.

Serg

i wonder if Starbucks is open . . . .but then again, i can't bring drinks into lab

Serg

TLDR

lim f(yawn) as t -> infinity = infinity

maybe i should get another coffee

all my attempts to quit everything don't work out too well

cl-netbox

Hello everybody ! :)

Serg

1:40 PM

hi

cl-netbox

@Serg Hey my friend - how are you doin' ? :)

Serg

cl-netbox

@Serg not very nice to read this ... :(

@Serg solution : go to bed ... now ! :)

@Serg good luck for best success ! :)

@Serg so not everything is bad ... :D

Rinzwind

boxy don't pm serg 5 times :(

people got kicked from chat for doing that

cl-netbox

@Rinzwind hmmm ... okay :)

@Rinzwind really ? what a great reason :(

Rinzwind

1:55 PM

It is. It is very annying getting 5 sounds quickly in a row

Serg

i personally don't mind :)

@cl-netbox can't go to bed now, i have class in 5 mins. I have 4 hour break after that so maybe I'll sleep for 2 hours but i can't right now

jokerdino

@Rinzwind Noted.

Rinzwind

@jokerdino that I missed an o? :X

jokerdino

One easy trick to annoy Rinzwind. You wouldn't have expected it!

I'm tempted to star that >:p

Byte Commander

following your example ;-)

blade19899

if command that compares date, and delete files that are 24 hours older then the current date... no find!

That is harder than I thaught!

Byte Commander

Even with "find" it's still complicated enough... I have no idea what exactly "find"'s definition of time is.

blade19899

@ByteCommander Yeah, fudge me.

Byte Commander

wait, I think I almost have something

test "$((86400+$(date -r="$file"+%s)))" -lt "$(date +%s)" && rm -- "$file"

@blade19899 something like that? ^

You can easily transform it into an if statement if you want to.

blade19899

2:47 PM

@ByteCommander Show me how xD

Byte Commander

file="~/testfile
if test "$((86400+$(date -r="$file"+%s)))" -lt "$(date +%s)" ; then
    rm -- "$file"
fi

You can also say if [ ... ] ; then or if [[ ... ]] ; then instead of if test ... ; then, but I personally prefer the version with as few brackets as possible. Not sure if there is any notable difference.

Rinzwind

can I block users in chat?

blade19899

You are missing a " in there? syntax coloring shows me that

terdon

@blade19899 You mean find -mtime 1 -delete?

Arronical

The missing " is in the 'file=' line.

terdon

2:53 PM

Or do you need to not use find for some reason?

Rinzwind

for the next week terdon is on ignore (...)

terdon

Sorry, couldn't resist.

And I really shouldn't have. I really don't like needless pinging. Still, you have to admit you asked for that one :)

Byte Commander

@blade19899 Oops, sorry. Yeah, it's missing at the end of the first line.

terdon

@ByteCommander You also don't want the =, use -r file or --reference=file

Byte Commander

Meh... :-/

terdon

2:57 PM

$ date -r=file
date: '=file': No such file or directory

Byte Commander

file="~/testfile"
if test "$((86400+$(date --reference="$file"+%s)))" -lt "$(date +%s)" ; then
    rm -- "$file"
fi

blade19899

> date: =/root/testfile+%s: No such file or directory
./test.sh: line 12: 86400+: syntax error: operand expected (error token is "+")

Byte Commander

yah yah... you're right

terdon

@blade19899 That's because of the =, try his edited version.

But why aren't you using find for this?

Byte Commander

He said not to use find. For whatever reason.

blade19899

2:58 PM

@terdon What does the date format need to be in testfile?

terdon

If you're on a non-GNU system, the date won't work either.

@blade19899 There's no date there. That's your target file.

blade19899

@terdon Don't have findas an option on that server. Can get a list of files, and their timestamps

terdon

@blade19899 What OS? You need GNU date for the other solution too, I think

blade19899

@terdon Linux CentOS 7.2

Byte Commander

And hasn't find a very special definition of when something is older than a day and when not? I believe to have read something strange in the manual there...

terdon

2:59 PM

@blade19899 Then why don't you have find?

@ByteCommander Yeah. It counts in 24h.

   -atime n
          File  was  last  accessed n*24 hours ago.  When find figures out
          how many 24-hour periods ago the file  was  last  accessed,  any
          fractional part is ignored, so to match -atime +1, a file has to
          have been accessed at least two days ago.

blade19899

@terdon It's a project I was tasked with, the server we have files on, need to be monitored. Meaning the deleting 24 hours and older files need to be removed.

terdon

@blade19899 OK, but I still don't understand why you don't want to use find. CentOS has find and find is the right tool for the job.

Stack Exchange

We are aware of issues on Stack Overflow right now. We are investigating.

Byte Commander

o.O

blade19899

@terdon yeah, but the files are not on CentOS, but on an external server, which is only allowed to use some basic tools like ls, which is why I can get the dates for those files.

grooveplex

3:03 PM

How can a program use 119% CPU?

Byte Commander

multi-core system.

grooveplex

So it maxes out one core and uses 19% of another core?

Byte Commander

Or 59.5% on two cores...

Rinzwind

@grooveplex with a loadbalancer it would be 2x 59.5 on 2

@ByteCommander >:)

grooveplex

okay thanks

Rinzwind

3:05 PM

bad user detected askubuntu.com/questions/827862/…

Byte Commander

@grooveplex Are you checking it in top?

You can turn Irix mode off by pressing I (Shift + i)

Then it shows total the percentage of all cores, instead of 100% representing one core.

terdon

@blade19899 Ah! Now it starts making more sense. But do not use ls|!

Why not post a question on U&L giving all the details and we can figure something out?

grooveplex

@ByteCommander time :O

Byte Commander

@Rinzwind placed some rude comment flags and a downgoat...

When noobs ask something but still think they know better than any expert answering them... Tsk tsk.

Stack Exchange

Stack Overflow appears to be stable again. We are keeping an eye on it.

@ByteCommander another one: askubuntu.com/questions/827856/… (not about ubuntu, nor about a service provided by Canonical)

Serg

3:39 PM

welp, that was uneventful wireshark lab

our university firewall blocks everything so we got same info for all nslookup queries

grooveplex

@Serg .......

:(

that must have been boring

Serg

eh, at least we don't have to write a report for this one

what's interesting though is that windows caches dns queries, Linux doesn't . dnsmasq does but I'll have to ask a question where is that cache stored

at least I'm happy that in this class we do something close to what i enjoy

i.e. computer stuffs

Byte Commander

next lesson would be to trick the firewall...

Serg

:D

they have no man pages shipped with it

try dart -h or dart --help

also why dart man dart ?

man dart is usually the way it's done
