What is an alternative to MSPaint in the Linux world, I googled it and every time it's "oh just use GIMP!" I don't want a massive loving photoshop suite to just crop or drop a colored box over stuff.

Every time, GIMP.

Hmm no good, it seg faults every time I try using the square block so I can censor out something.

Strange how the program with less features is the most troublesome to find when it comes to image manipulation.

How can I temporarily prevent my monitors from entering power saving mode? I run moc (cli music player) and set the output device to a TV over HDMI. This is in my bash.rc which I use when I want to play music on the TV.

Bash code:

function mtv() {
    mocp --music-dir $(pwd) --theme black_theme --set-option ALSADevice=tv
}

Ideally I'd like something I can just run with that command that will temporarily prevent screen sleep. I don't want to make permanent changes since this is literally the only situation I don't want the monitors to enter power saving mode.

Is this possible?

One way to do this is to do what mplayer does, have the capability to run an arbitrary "heartbeat" command every once in a while to simulate activity. It doesn't look like moc has this option but it does let you run an arbitrary command when the song changes so you can just use that (assuming your songs are shorter than your screensaver timeout of course). An example of something to run might be

code:

xscreensaver-command -deactivate >/dev/null

There other ways to go about doing this depending on how fancy you want to get, cron immediately comes to mind for example.

Xik: Mar 10, 2011; Dinosaur Gum

I did some quick reading, I don't have xscreensaver installed so that is not responsible for managing DPMS. Xorg auto detects and enables it apparently. I guess the default has been fine so I've never bothered to learn about configuring it.

Reading the wiki, I think I can use setterm to set blank and powerdown off for a particular virtual terminal. So if I shove something like:

code:

setterm -blank 0 -powerdown 0

into the bash function I use to call moc it should do it. Then when I exit moc and close that virtual terminal it should go back to normal power saving. I'm guessing so anyway, I don't really have any idea what I'm doing and am just going by what the man page seems to say... I'll give it a go and see what happens.

edit: Or I could just do what evol says... thanks!

double edit: I think I'll just need to modify the dpms setting since I don't have a screensaver.

The AUR can be a great resource and I'm a fan of pkgbuilds for stuff I would otherwise have to manually manage. If you're just discovering it though you should read about the security implications of installing stuff from the AUR.

I really like Mint 16, but keep in mind 16 is only supported through July. 17 is coming out at the end of May and will be a lts release, based on the just-released Ubuntu lts.

So I wrote this cool sed expression:

sed -e 's/$^.*tracker_$$.*$$:.*$$:.*$/\2/'

For this string:

tracker_ip-10-85-57-55.ec2.internal:localhost/127.0.0.1:49191

To get this:

ip-10-85-57-55.ec2.internal

But it doesn't work for this:

tracker_ip-10-21-199-91.ec2.internal:45454

I'm assuming it's because I have it looking for two occurrences of : as if I remove the second one then it comes out right. In my head it's supposed to give me everything between tracker_ and the first occurrence of : but my head is bad at regex.

Regexes are greedy by default: each component will attempt to match the largest possible chunk. So if your regex has only one part with the colon, it tends to match everything until the last available colon unless something else stops it from doing that.

You already got an awk-based solution, but for the sake of regex practice, here's mine:

code:


sed -e 's/^.*tracker_\([^:]*\):.*$/\1/'

Translation:
From the beginning of a line, there is some un-interesting stuff that ends with "tracker_", then the (first) interesting part begins. The interesting part can contain any characters other than a colon. When a colon is seen, the interesting part is over and anything after that (including the colon) until the end of line is non-interesting again. Now, replace it all with just the interesting part #1.

You might have some other requirements, but this is what I would write to get just the part you described with your examples.

This is the point where you drop sed and go to something that can do pcres.

code:

echo -n tracker_ip-10-85-57-55.ec2.internal:localhost/127.0.0.1:49191 | perl -lpe '$_ =~ s/^tracker_(ip-.*?):.*/$1/;'
echo -n tracker_ip-10-21-199-91.ec2.internal:45454 | perl -lpe '$_ =~ s/^tracker_(ip-.*?):.*/$1/;'

echo -n tracker_ip-10-85-57-55.ec2.internal:localhost/127.0.0.1:49191 |python -c "import re, sys; print(re.sub(r'^tracker_(ip-.*?):.*', r'\1', sys.stdin.read()))"
echo -n tracker_ip-10-21-199-91.ec2.internal:45454 | python -c "import re, sys; print(re.sub(r'^tracker_(ip-.*?):.*', r'\1', sys.stdin.read()))"

echo tracker_ip-10-21-199-91.ec2.internal:45454 | ruby -e "puts STDIN.read.downcase.gsub(/^tracker_(ip-.*?):.*/, '\1')

I mean, you can do it with sed/POSIX regexps. But you end up doing pretty ugly things.

code:

sed -e 's/^.*tracker_\([^:]*\).*/\1/'

Which says "from the beginning of the string, eat everything until you encounter the last instance of tracker_ (non-greedy matching is a good reason to dump sed), then start a new capture group. Take the group of all characters except a colon and match, then suck up the rest of our string and put the capture in".

This works because . is a set of all characters, basically, and [^:]* says "remove colon from the list of characters you're willing to match, then match zero or more occurrences", which stops it dead at the first colon it finds but lets it match everything else. And this way, you can approximate non-greedy matching in sed. But it's a hack. And it gets unwieldy really fast when you get more complicated regexps. Learn PCREs and use whatever language they use in your environment.

E: beaten to it by telcoM :corsair:

Hot drat, you guys know your stuff. I was going to use awk but didn't want to rely on FS as I'm extracting a hostname/IP from the string and there's a chance the hostname will contain a _. From there I decided to use sed because I knew it could do regex, then things got a little messy because I suck at it.

I'm trying to rely on system tools as much as possible since I'm writing a script that will be shared with lots of external parties, I'm basically using printf, sed, ssh, and scp throughout the script. I considered switching to Perl but I barely know how to use it and last time I went on #perl everyone yelled at me for calling shell commands.

Complete Linux newbie, so bear with me (and forgive me for not reading all 400+ pages of the thread).

I'm a former part-time small office computer janitor who has done a tiny bit of work in *nix systems before, so let's assume I'm barely capable.

I've got a 6 year old Dell Vostro (running XP pro) that runs just fine, but it's pretty bogged down with modern era software. All I want to be able to do with it is web browse (with the requisite multi-media plugins so that pandora/youtube/etc still work) and run open office, or even just use Google Docs. I've always wanted to play with a Linux machine, so this seems like a pretty good excuse to start.

Is Lubuntu a good choice for this? If not, should I install something else? The laptop reports linked in the OP have Vostro 1000s running Ubuntu (7.10 and 8.10) and Kubuntu 8.04, but I'd rather run something lightweight but new.
