Now I would like to create a third file which contains only those packages which are present in package-a.txt but NOT in package-b.txt. The file should look like this:
Code:
package2
package4
Note: The world "install" is also to be removed for all packages. Using diff command I could get something like this:
I am trying to extract 2 numbers from a same file and my goal is to print them both in another file, on the same line, separated with a space. I have to do that for 20 files and I would like to have therefore 20 lines like this in the output file. It would look like this :
And I did this by running a bash script with the following content :
Code:
#!/bin/bash ls execution$1$2*.* | while read filename do cat $filename | grep -e "Total aborts:" | cut -d " " -f3 >> abort$1$2.dat done
$1 and $2 are just strings to identify the different files I want to consider in this loop. This script works well to extract a number which is the 3rd field of a line starting with "Total aborts:".Now, how could I change this script to do what I mentioned above (i.e. extracting two numbers from two different lines) ? The second number is the 3rd field of a line starting with "Total throughput:"
I have this string ./DAT000728-652523058.job.I want to extract the no between DAT and - sign. I want 728. I dont want 000728.echo ./DAT000725-560162365.job | cut -d'T' -f2 | cut -d'-' -f1 I am getting 000728.string can be ./DAT326822-652523058.job also. then i need 326822
I am trying to write commands that extracts the height and width of a video file via ffmpeg. I have the following working so far:
This gives the following answer in widthxheight format with an extra , 720x480,
How can I instead run 2 separate commands that give me height and width separately? I want some command to give me 720 and another command to give me 480 and I dont need the x or the ,
If you need to know this is what ffmpeg -i videofile.mov 2>&1 gives as output
I'm trying to extract specific lines from a flat file. I need lines that fall within a range of coordinates. The -F can be either ! or = If the line is in this set range I need all of the data on that line. ranges lat 36 to 39 and longitude -74 to -84
I want to make a rescue disc for debian such that if anything goes wrong everything can be restored to its original condition. whatever extra packages are installed they should also be put back. most importantly zimbra and its dependencies.
if there is a way of downloading some extra packages and including some extra repositories that will automatically install during the main installation? With the option of a few settings being saved too... like for those that are used to windows having the gnome menu on the bottom.
I am promoting and convincing a lot of people to try Linux and I always recommend fedora as the OS of choice. I have no interest in creating my own distro, because I love Fedora. I just want to make sure these users can have all the codecs and little extras that makes computing fun without being a geek.My main issue is when I wipe their HDD and install Fedora, I then have to repeat the same tweaks and installs every time. This is my 7th time doing the exact same install and am looking for a quicker way.
I want to know how to install KDE on Ubuntu and Gnome on Kubuntu. The commands apt-get install ubuntu-desktop apt-get install kubuntu-desktop are not the solution, because they install all distro packages, and I want only the base of desktops KDE and Gnome.
I can install LXDE with apt-get install lxde instead of apt-get install lubuntu-desktop
I can install Xfce with apt-get install xfce4 instead of apt-get install xubuntu-desktop However, I could not do the same with KDE and Gnome.
if I wanted to install all the packages from the slackware cd in the extra dirctory do I have to install them one by one or is there a way to install them all at once?
Install One : Installed Debian Squeeze onto my laptop using the netinst cd. During installation, I did not have access to the internet and installed "Standard System" during tasksel.
Install Two : Installed Debian Sqeeze onto my desktop using the same netinst cd. However, this time I had connected the desktop to my router during installation. Similary installed "Standard System".
Both system later installed with KDE and working fine. Noticed that immediate after installation of the "Standard System", my desktop had more files installed eg. the exim package. Why the extra packages (eg exim) are installed? Are they actually required?
how to add packages to an existing Ubuntu ISO or LiveCD (Think like slipstreaming Windows Service Packs into Windows installation CDs, if that helps). I want to add things such as more games or the restricted extras plugins so that I don't have to go get them every time I install the OS on someone's computer, things like that. Not as important, but if it would be possible to remove packages
PS I'm not necessarily looking for a specific version, but I'm currently running 9.10 on one machine and 10.04 (soon to be 10.10) on another. A guide for any Ubuntu distro would be fine though. I'm just as interested in learning the theory of it as I am the actual execution.
I have downloaded fedora 9 iso to my xp os so I can dual boot my machine. I can't seem to find a place to plug up my RJ-45 to download the extras package in an RPM or a tar file so that I can transfer it onto my linux os so I need a wireless site to download from.
I upgraded my dedicated server using the do-release-upgrade command, and it seems to have installed many extra packages I do not require. This is a headless server in a datacentre, yet the upgrade caused me to install GUI packages I do not need. Is there a way to quickly remove all but the default server packages?
I'm having a hard time figuring out why the program posted below prints an extra newline every time I type the enter key.This program is using the master pseudo-terminal to send the password and receive the output from the slave(connected to the passwd program).I suspect this has to do with the terminal line discipline(s)(2 considering the master and slave), but I can't really understand why.I have tried turning on/off several terminal special characters but to no avail.
I'm trying to search through some pdf files and I'm doing so by converting them to text files using pdftotext which is fine but I'm trying to get the number of occurrences in a paragraph of different words and it's adding a new line character at what it thinks is the right hand margin. I'm trying to remove all these singe new line characters but keep the doubles and I can't seem to work it out. i.e.
This is some text that has been broken. Another paragraph. becomes This is some text that has been broken. Another paragraph
When ever I extract a file from a .tar or whatever, it isn't detected. I notice this mainly when i'm using xampp. I copy zip up all my files on one computer, load ubuntu on another, extract the files to the web folder (htdocs) and then I get nothing. However, when I manually create the files directly on my computer as opposed to extracting them, they appear.
Is there something I need to do in order to have these files appear? Is there some sort of file system refresh? Or am I being a complete idiot?
there are 2 related to 11.3: openSUSE_11.3/ and openSUSE_11.3_KDE_Distro_Factory/ Index of /repositories/KDE:/Extra they are not listed as official kde4 repos here KDE repositories - openSUSE, but they are in the same directory structure on the build service so it would assume they are official (what ever official means) They have rpm's I didn't see in community and playground (at least for 11.3) such as audex and clementine I would guess that they are for the stable and factory versions of KDE4 but then shouldn't there be a 3rd for unstable if this was the case? Or do they refer to the distro, 11.3 stable and 11.3 factory
I've noticed when I create a generic textfile in vim and have a trailing newline at the end of the file, when I open it with kate it has 2 new lines at the end of the file instead! This is on a fedora machine. The same behavior is observed when I copy the file over to my windows machine and open it in notepad++ (which is able to handle both unix and dos newlines) - 2 newlines instead of 1.
Feeling curious, I tried creating a textfile in vim on my ubuntu machine and used gedit to open it, but surprisingly gedit displayed it correctly - only 1 newline.
I need to extract a price from a string, this may vary in the future so it may be 12.99 or 14.99. i thought a sed command might crack it and i need to write to a file:<td><b class="priceLarge">?6.99</b>I need to extract the price 6.99(with no ?)so extract anyhting between "> and </B> and write it to a file such as tmp1.txt .
I am trying to extract a web page via Google for processing. I am able to create a proper query and test it using cut/paste into the address bar of my firefox browser.
When I attempt to extract the page with wget: wget -O - -q "$query" I do not see the information that is present when I used the browser.
I have many files in a folder from which I need to extract some contents, these are basically text files wich have individual lines with (i.e)
name: john address: whatever phone: 123456
Some caveats
1. Sometimes a line might be missing.
name: johnn phone: 123456
2. Lines are not in the same line-numbers across the files I did try some things with awk based on google searches but I couldn't extract the data of each file into a single line (this is the ultimate goal):
john,whatever,123456
I don't have knowledge other than having put some bash scripts together for backup jobs, so I am open to install anything that could to pull this off.
I'm trying to create an application that monitors, among other things, what site the user is currently viewing. I would like to know if there is any way to get the current URL from the Firefox's address bar on a Linux machine. I know that under Windows I can use the DDE server approach, but under Linux this task is proving very tricky. I've considered an approach involving an extension to Firefox, but this would require the user to install the said extension himself. Which is not something I want. If an extension can be installed by a different program's installer than that could work, but I don't know if that's possible or not.
The idea is to make a website to check the availability of domains and it works but its not pretty yet. Below is what i have till so far:
## this is the API from my domain registrar. <?php $client = new SoapClient('http://api.sync.com/?wsdl'); ## I have a search box that sends the request to this page $var = $_GET ["s"];
## remove the most common subdomains from the request. $var=eregi_replace("www.", "", $var); $var=eregi_replace("mail.", "", $var); $var=eregi_replace("ftp.", "", $var); $var=eregi_replace("pop.", "", $var); $var=eregi_replace("smtp.", "", $var);
## remove any TLD extension from the request. $split = explode(".", $var); $main = $split[0]; $arraysize = sizeof($split); for ($x=1; $x<$arraysize; $x++) { $tld .= "." . $split[$x]; } ## login to the API $paramLogin = array('handle' => 'randall', 'password' => 'password');
Result Login: Array ( [code] => 200 [message] => Login succesful ) array(3) { ["code"]=> string(3) "200" ["message"]=> string(20) "Domain not available" ["result"]=> object(stdClass)#236 (1) { ["status"]=> string(5) "TAKEN" } } bool(true) array(3) { ["code"]=> string(3) "200" ["message"]=> string(16) "Domain available" ["result"]=> object(stdClass)#232 (1) { ["status"]=> string(4) "FREE" } } bool(true) ?> ## till so far it works
What I need to do is to make this ugly looking reply in to something more readable, basically if TAKEN print occupied and if free print its yours to grab. I have been struggling with the in_array function but i'm not getting anywhere close in getting it to work.
I am trying to get the metadata out from an image file in python. I have tried using PIL but it does not give me the data I am looking for (mostly just got a bunch of hex code) and I have no idea how to use ImageMagick, the python module is poorly documented and I can't find any examples on the net.The info I need is stuff like camera model, if flash was used, focal length, exposure time, date, etc.. pretty much the same info I get when I look at the "Image" tab on properties in Nautilus on Ubuntu.
What I am doing is writing a script that will iterate through a lot of pictures and put all this metadata into MySQL. I chose python since it is simple and I am familiar with it. But I can't find a good way to get that metadata from within python.
I have a file that contains a couple of email addresses and I want to extract the usernames ( Letters before @ symbol ). How can I do that using sed/awk.
I know cut will work, but the current environment doesn't allow me to use cut command. I can use either awk or sed.
I have a small bash/awk program that extracts the date/time/size of thousands of email headers. I'm trying to also extract the last "Received from:" string from these email headers which will give me the senders email server. on extracting the last occurrence of this string, and printing the information after it?
