How To Select Newest "dated" Directory?

Hi,
I have a /backup directory which contains 5 days worth of backups:
2015-03-12_03-01-07
2015-03-11_03-01-07
2015-03-10_03-01-07
2015-03-09_03-01-07
2015-03-13_03-01-07

I need to copy the content of the NEWEST backup. Ideally, I'd like to find newest backup and assign it to a variable for later use.
I know I can Code:
ls -lt

to sort directories, but how do I pick the first one and store it into a variable?

Thanks,

Hi

I am using this command to get some info about bots/spiders from my Centos server access.log file:

Code:
grep 'spider\|bot' access.log | sort -u -f >> bots.txt

Result is like this (i know pingdom is not bad):

Code:

Is there any command that can remove duplicate lines if the ip and the user-agent is the same on each line?

To get something like:

Code:
141.101.105.102 - - [28/Mar/2015:01:59:56 +0200] "GET / HTTP/1.1" 200 24194 "-" "Pingdom.com_bot_version_1.4_(http://www.pingdom.com/)"
141.101.105.158 - - [28/Mar/2015:02:09:56 +0200] "GET / HTTP/1.1" 200 24260 "-" "Pingdom.com_bot_version_1.4_(http://www.pingdom.com/)"
108.162.215.53 - - [27/Mar/2015:23:11:59 +0200] "GET /user/275904-ktlk21/ HTTP/1.1" 200 3805 "-" "Sogou web spider/4.0(+http://www.sogou.com/docs/help/webmasters.htm#07)"
108.162.215.75 - - [27/Mar/2015:23:21:31 +0200] "GET /user/74595-tery1/?tab=topics HTTP/1.1" 200 13588 "-" "Sogou web spider/4.0(+http://www.sogou.com/docs/help/webmasters.htm#07)"

Or if there is no way for this then to get only one line (even if different ip's exist for each user agent) like:

Code:
141.101.105.102 - - [28/Mar/2015:01:59:56 +0200] "GET / HTTP/1.1" 200 24194 "-" "Pingdom.com_bot_version_1.4_(http://www.pingdom.com/)"
108.162.215.53 - - [27/Mar/2015:23:11:59 +0200] "GET /user/275904-ktlk21/ HTTP/1.1" 200 3805 "-" "Sogou web spider/4.0(+http://www.sogou.com/docs/help/webmasters.htm#07)"

Process Substitution With Awk, Output Splitting Incorrectly

I have the following code to extract two dates using awk, which are then read into two awk variables new and old respectively.
Each dates on the html file pulled with curl request is in this format:
2015-04-06 09:40:37
And two are being extracted
However the strings are being split on white space within the date strings. I tried changing OFS to ',', but it was still splitting incorrectly.
Code:
read dateStrNew dateStrOld < <(curl -k -q "$curl_call" | html2text | gawk '/Newest Sequence/ { new=$3" "$4 }/Oldest Sequence/ \
 {old=$3" "$4}END {OFS=","; print new,old }')  //new = date, old = date

Both parts of the date are being assigned to each variable using $3 and $4, then the space needs to be added back in so that the string can be used afterwards with a date command.

I just can't work out what is wrong, any help would be very much appreciated! Thanks!

Bash Echo Date+string In The Same Line

I would like to print the date followed by a string (an indication of what's going on at that time) to a file. With this intention I've tried

Code:
date >> date.txt && echo "something start" >> date.txt

That gives me

Code:
Sun May 17 01:08:28 BRT 2015
something start

How to get both at the same line? Like this

Code:
Sun May 17 01:08:28 BRT 2015 something start

Need Help Understanding Luckybackup

gold finger was kind enough to share this with me a while ago:

Quote:
Do backups to either another HDD, partition, or a USB stick (if big enough to hold your data). Can use program to make an initial backup of /home/gregory; then use it to periodically update that backup by having it sync between your installed Xubuntu /home/gregory and the backup copy. The sync function will just copy over things that are new or changed, rather than copying everything all over again.

Assuming your Xubuntu filesystem is Ext4, example of doing initial backup would be something like this:

* Spare USB with large partition formatted as Ext4 and labeled "BACKUPS"
* Open luckybackup and choose "Backup" function
* "Source" = /home/gregory
* "Destination" = /media/gregory/BACKUPS (might be under /media/BACKUPS)
* Check box to not create new directories (it will just do exact copy of source)


After initial backup, either make a new task for syncing, or modify the backup task to turn it into a syncing task instead. Then use that periodically to update the backed-up /home/gregory.
I've downloaded Luckybackup and have been experimenting with it but I'm still not sure the best way to go about using it as a backup. Like in gold finger's advice, why would I check the box to not create new directories? It seems to me doing it without checking the box re-creates things just the way they are on my computer. When I check the box it just takes everything out of the folders. Seems confusing (and unnecessasry). And I have a really hard time finding the errors after a run and when I do find them I do I don't know what they mean. And so if I backup the source destination it makes an exact copy on my destination drive (with folders if I don't check the box, without if I do). Then if I do that as an ongoing thing, I will be backing up all my data with each run (which I'm assuming would be much more time consuming), whereas if I choose 'syncrhonize source and destination' it will only backup the changes in my source and usb drive (which would be my destination drive)?

Is that the idea?

And I noticed that Lucky did not want to transfer things with colons in them. Googling around somebody said that problem would be taken care of by switching to ext 3 or ext 4 for formatting the destination drive (as gold finger suggested). Is this a good idea? (I've always felt comfortabel with FAT because if I needed to plug my flash drive into Microsoft it would work (as well as with Linux).)

So the first time I use Lucky I choose "backup source inside destination" and of course the source and destination. Should I check the "Do NOT create extra directory" box? (Again, that seems off as 95% of what I'll be backing up is in folders.)

Then after I've done that, I choose the snyc option?

A lot of stuff. I know. Thanks.

PS. As a slight complication I have the data (basically the "home" folder) of my two computers (work and home) synced via Copy.com.

Ubuntu Directories

Hi there. I have Ubuntu 14.04 installed. Actually I have been doing a lot of work in this OS for about a year. The thing I cannot still comprehend is how to find files I installed. In this particular case I need glut.h for g++ compiler. So I go here, do this command;

Code:
sudo apt-get install freeglut3-dev

And find out that I already have the newest version (which I have suspected since I recall installing it).

So, the next step is to find the glut.h file and reference it with #include command. I cannot find it anywhere. This website says it has to be he

Code:
/usr/lib/x86_64-linux-gnu/libglut*

Why's the asterisk? Is it a footnote or part of the code?

I don't seem to have /usr/ directory. I cannot find it anywhere.

How does Ubuntu directory work?

Thanks, - A.

Libreoffice Cannot Find Network Printer, Offers Only (non-existent) Generic Printer

Arch linux, lxdm/lxde, recent installation, feeling I must be doing something stupid, would be glad to be guided!

I have a Brother HL-2030 printer connected to a Raspberry Pi as a print server, CUPS setup, with sharing turned on. Other machines in the household, and indeed other OS's on the machine I'm writing on, print trouble-free to this printer.

On *this* desktop machine, (with libcups installed,) other programs print trouble-free. Firefox, Thunderbird, geany and evince all detect the presence of the network printer, and work as expected.

It's just Libreoffice that does not. This is true both of libreoffice-fresh and libreoffice-still, and it is true for all the components (write, draw, calc etc).

Libreoffice *does* find the network printer from other OS's that I play with; I have Puppy and Mint on the same machine, but those installs of Libreoffice are obviously different/earlier versions (nor do I feel like upgrading them in the circumstances!)

In this context, though, the Libreoffice "File>Printer settings..." menu offers me only a "Generic Printer" (whose properties and options I can edit). If I ask Libreoffice to print to this generic printer, it reports no failure, but that task just seems to disappear into thin air.

On the Pi server, /var/log/cups/ offers

Code:

I really think I must be doing something very stupid and newbie-ish!

Dd Command For Backing Up Linux OS..am I Doing This Right?

hey guys, I understand how dd works. Ive been researching on it and I see that
if="" is the source of what I want to copy
of="" is that target that I want to send the back up to

so, what i am trying to do it copy my hard drive from saturn server: /dev/sda1 over SSH to my backup server skyline.

so [saturn harddrive /dev/sda1] -----backup---> [skyline:/backup/directory]


this is the command I am using
sudo ssh willc86@skyline "dd if=/dev/sda1 " | dd of=/backup/saturn.img

however, it is saying failed to open /dev/sda1/ : permission denied and I am runnign as root. any idea why?

thanks a bunch guys!

Script Queries

Hi,

Below is the output of the "date" command:
Thu Apr 2 16:07:59 SGT 2015

After assigning the output to a parameter as follows:
DATE=`date`

The output has changed when "echo $DATE":
Thu Apr 2 16:09:40 SGT 2015
^^

The "2" has moved forward.

I don't want the "2" to move forward, please advise how to go about it.

Thanks in advance.

Rsync, Reliable "copy And Paste" Type Of Backup In Case Things Break?

What I did in windows was create images of my drive and restore them.

in linux I am running

Code:
rsync -aAXv --exclude={"/home/*","/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} /* /path/to/backup/folder

and this creates a folder for me with all my files, and apparently saves meta data like permissions and paths...

Since I'm using arch and things break sometimes,I'm booted into a CLI with errors and cannot figure my way out since I'm a noob... would I be able to just delete my entire root and replace it with the rsync backup without a problem?
