i am reading a database flat file with the "awk" command which has 4 fields separated by colon ":" .I want to show the output of these fields in a certain way that every record is numbered e.g
1.some text
2.some text
Is there a way to do this?
How would I list 4 users ID numbered 10, 11, 12 and 13 from my users list and output them to a file busers where their names are numbered by ascending order? How would I accomplish that on a one line command?
View 4 Replies View RelatedI'm writing a couple of programs in C and need to do something to formatting the output. I'm after producing something like a old mainframe screen or early micro where you could PRINT (x,y) to put something on the terminal where you want it. Learning GTK or such is not an option due to time constraints, and some fields need updating frequently during processing, so letting the terminal scroll is going to drive the operator up the wall pretty quickly.

I have a file with 200 000 lines and I want to append the fields of each line based on matching first field. The resulting file should have 70 000 columns but has "only" 18 000. The command I'm using is working perfectly with a smaller file, wich lead to 14 000 columns. Could there be a limit in number of fields that awk can handle ? Here's my awk command :
Code:
awk -F, 'END { for (k in _) print _[k] } { _[$1] = $1 in _ ? _[$1] FS $4 : $1","$4 } ' file > out
Also, this command writes ^M (windows line break) after each columns. Removing them is easy but where do they come from ? Working on Ubuntu 10.10
I have an array called @logons. How can I step thru the array and split the fields? This is what I have so far, but doesnt work. I got the feeling I the split statement syntax is incorrect.
Code:
print @logons;
foreach my $logons(@logons){
($userid, $ip) = split(',',$logons);
[code]....
Update: Appears the data in @logons has a column header from the mysql query which I used to populate it with. So that code which I was testing does indeed work.
I want to write a function which calculates the space needed between fields, to generate a table with aligned fields, like when you type "ls -l", the operating system generates a table with beautifully aligned fields. I've got this code so far:
Code:

do
line=`echo $line | tr ":" " "`

constructing a protocol where in it involves sending and receiving different files, so sending data over consists of file name, size of the file and content of the file, so while receiving can i use functions like strchr() to differentiate these fields for sockets? so to allocate memory for file to save i need to have its size.
View 3 Replies View RelatedI am faced with the following problem; I need to update all fields of type datetime without ... with the following sort data:01-01-2010 12:10:30.256 - this is just an example.these fields are restricted with a unique constrained. My question is how can I generate the above sort data, especially the last three numbers with leading point. After that how can I update a table with existing data with this newly generated data so that the fields really do carry unique data.As you probably can read out of my question, I read through the help in pgAdmin and came as far as generating date, maybe datetime but not the .123 number. And a little insert script I found in the help, that I modified as UPDATE resulted in updating only the last generated data in all required fields.

A few days ago I setup a pc. It contains an "Intel ICH5" sound card. Before I begin posting all the configuration stuff I've tried so far what the standard procedures are to set it all up for recording the sound card output (with Audacity)?
On my older computer it all worked fine but now I only get silent recordings. However sometimes (when I played on the controls the right way...) I get recordings where you can (amoung some noise) recognize the stuff I actually wanted to record very low... Apart from Audacity I've also tried
Code:
arecord -vv -fdat audio.wav
which didn't work either. That's why I think the problem is not related to Audacity but to the system.
Is the combination of OpenSuse 11.2 + ALSA + Intel ICH5 commonly known to cause such trouble?
I am wondering how i would do this using VLC (i want both video and audio to be recored),
i see this RTSP Protocol people use but no idea how to use this for a website thats going to have a live show on.
By the way the thing i want to record will be here http://e3.nintendo.com.
Would it be rtsp://e3.nintendo.com?
hopefully thats a link that can be recorded...right?
the reason i want to record this is because i got a test i have to take... i gotta stay for like 2 hours.
I am currently trying to start doing some screen casting and having a problem with audio recording in gtk-recordmydesktop. The problem is that I need to record both; my computers audio card output, and my mic input at the same time. As of now I am able to record one or the other.
View 4 Replies View RelatedI want to display the contents of a particular log file (simple text file, I mean in Linux). But there is a problem: The contents need to be organized in a fixed format. Have a look at this log file:
sampleLog.txt
Code:
User Name: XYZ
Reported Problems Description: Blah! Blah! Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah!

So, while displaying the contents of above file on a web page, I want to format the field names found in the log file: User Name:, Reported Problems Description:, and Remarks:. These fields may contain a variable length of text and no specific line number is assumed for them to appear on.
The desired output should look like this:
User Name: XYZ
Reported Problems Description: Blah! Blah! Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah! Blah!Blah!

Well, what I am trying to do may sound wierd to some of you. The filed "Reported Problems Description:" can possible contain text which embeds colon (.
I forgot a lot of my command line. I am doing cat file | grep "error" and i would like it to show everything to the right of G:/ including G:/ if possible. I figure its an awk command but i dont know what. I tried awk '{print $8+}' but + does not work like i hoped and guessed.

record my radio show from a radio I have plugged into my iMac. That's right. For now, I am dual booting on my iMac until I can afford to buy a dedicated PC desktop just for Ubuntu.
I can't believe that there seems to be no way for me to record my shows from my radio. Works fine when I boot into the Mac side and even when I use Ubuntu using VMware Fusion. When I boot into Ubuntu directly, Audio In in the Sound preferences doesn't seem to work. No audio coming through when I try to record from the radio.

View 5 Replies View RelatedI currently use cp to backup data. I prefer it over rsync. I use the -b switch to make a backup of data and recently found you can use --backup=t to create numbered backups.Using --backup=t means that I could end up having 100 versions of a file if I change it 100 times. With the -b switch I will only ever have 2 versions. Is it possible to limit the numbered backups to 5 for example? So I would only ever have 5 versions?
