Code: s8 IEEE80211_RADIOTAP_DBM_ANTSIGNAL now, when I printf it:

I am writting a program that reads a text file (music.txt) & stores it in a Data Structure. I am a novice learning over the internet so I this is something I have never done. How do I do this?
Quote:
Write a program that reads the data from the music.txt file and store it in a data structure. To implement this data structure you must use an array of songs and each song must be represented by a struct with appropriate fields. So far all I can do is open to file to read it (very simple I know) but so far is it correct?
I am running Debian on a 4 years old pentium machine. I have recently switched from Windows to Linux, so I'm still preferring the graphical user interface (Gnome is very good for me).
Now my problem: My harddisk becomes too small for the data I am storing and processing (pics, music, videos), and I would like to fit a larger one. So afterwards, I will need to reinstall debian and all the software I now have in it. How can I store a list of the currently installed software? (I can view it with the gnome apt software manager (also with synaptic), but I did not find a way how to store or print it).
Or, could I possibly save the whole system on an external harddisk and restore from that afterwards, as I do with the data?
I am using an awk command to print a line from a cvs file.the awk command includes an if statement that filter the output-lets say i want to print all the lines that the price field is greater than 30.i have it working when i put the parameters myself.. but when i try to send them with vars it wont work..i am sending the sign of the if statement - can only be: == , < , >it looks like this:
I having the following awk line in a script, is it possible to modify the script so that it create a the directory if it dosnt exist (similar to mkdir -p) awk -v datum="$DATUM" -v workingdir="$workingdir" '{ sub("\[.*","",$5); print > workingdir"/"datum "/" $5;}' $1
I am trying to compare a list of patterns from one file and grep them against another file and print out only the unique patterns. Unfortunately these files are so large that they have yet to run to completion. Here's the command that I used:
Code: grep -L -f file_one.txt file_two.txt > output.output Here's some example data:
I have a problem with arrays in awk. What i want is to take some data from a file (ssh log) and print it to a html table. I have managed to print some stuff (user logged in and how many times they have logged in) What i want more is to take all the ip that each user logged in from and print it in a row next to the username and times (in the code i typed blabbla where i want the ip to be shown. How do you think i should approch that, multidimensional arrys maybe?

I have two students whose windows laptops are riddled with malware and not working properly. They want me to help them install Linux (which we use in school), but they are concerned about their iTunes.
Having avoided iPods as "defective by design", I know nothing about iTunes whatsoever. However I remember reading about DRM locking and such problems that have me concerned that I won't be able to do it.
Where does iTunes store its stuff?
Can I copy its data store to an external drive, and then into a linux home?
Then will it work on wine, or can another manager (rhythmbox etc) access the itunes data?
Alternatively, if I partition the drive and install linux, can rythmbox/wine/something access itunes data on the win partition?
Supposing they are buying music through iTunes, what will happen to that account?
Finally, one of them has an iphone. Does that work with linux?
Ironic that an apple application is blocking migration away from windows.
i have a loop which produces new value everytime it runs. i want to store the results in an array. how can i do dat??
loop is like: a=0 declare v while ((....)) do v[$a]="$r" let a=a+1 done
while doing this it is not treating v as array but as variable and it is overriding the value and old value is lost..i am using bash shell version 3.00.15
I am trying to store the data in my program in a map of priority_queues an I am having a bit of trouble doing it. basically I am storing activities (ie watching tv, eating dinner, playing ping-pong, etc) and I want these event grouped by the day that they happened on. my first thought was to use a multimap where the key is the date, and the value is the activity, however I would like to keep the activities in a specific order. I have tried to find the proper syntax for this but have frustratingly come up empty. Even google provided little assistance.
