I tried, of course:
Code:
awk '/^./ {print}' FILE.TXT
That does not work, I just get an empty output, even if FILE.TXT contains lines which fit the desired regexp I've searched but did not found my way. I'd like to do it with awk, as I want my program to rely only on awk, nothing else such as sed, grep, etc.

I need a substitution of a particular string (StringA) with another string (StringB). However, there may be more than one occurrence of StringA within the file, but only one instance needs to be changed, which is why I'm trying to be sure of it's positioning against something I know will be unique in the file, and will always have the same distance from the string to be replaced. So, I intend to match on a string (StringC) above the string to be substituted and then have sed go to StringA below and replace with StringB.
So far, I have had some success with the following:

I am working on debian based OS and my query is,how to make detect the Number of NIC's plugged on a PC.
I describe it: Exact requirement would, assume, If I plug 3 NIC's for a PC,one for Internal Network,one for External Network and Other remaining one for DMZ,so I need to make an application(Firewall Kind)in such a way that,once my PC is started,it should detect how many NIC's are plugged and Whats their role played(As Mentioned above)..?
I hope u guys got a basic idea on what and how it it can be implemented..

A function by name abc is called in many files. I want to copy all the lines with the function call to an output file.A simple grep on function name doesn't help me as the function call is spanning across multiple lines as follows:
abc(parameter1,
parameter2,
parameter3);
So I want to copy all the three lines (till semicolon) to the output file.The problem is because there are more than 200 calls for the same function and I cannot do it manually

View 1 Replies View RelatedI installed Ubuntu 9.10 yesterday on my computer. I had Windows XP and Windows 7 (I deleted the Windows 7 partition and installed Ubuntu 9.10). However, after installing Ubuntu, I couldn't access the grub boot menu. So I googled, and I found out how to make the menu show up again. That was okay. But Windows XP didn't show up. So I googled a bit more, searched the forums, and I added the following entry to my 40_custom file code...
As far as I know, that should work. The uuid I entered there is the one that gparted told me was the uuid of the partition. However, this isn't working. I get a disk read error when I try to boot my Windows XP.
According to my gparted, my Windows XP drive is inside an extended partition? I wonder if that has any influence on why I'm getting the disk read error, or anything. It's either that, or my 40_custom entry is wrong. I've been trying to sort this out for a while now, and I'm afraid I'm not getting anywhere with it.
I installed a sound card but when I go to System->Preferences->Sound and go to Hardware it's not showing anything at all. If I boot from the Live CD then it will show the card and it works. How can I make my Linux installation detect this card? I was thinking that I could somehow copy the necessary files from the Live CD to make this work, but maybe there's an easier way.
View 1 Replies View RelatedI need to write a small application which needs to detect if the system time is changed by an another application/user and perform some action as soon as it is detected (maybe log the data that time has changed, along with info about which application/user changed it).
How can this be achieved?
I have good programming experiences in shell script, c and beginner level in python.
I don't need to know when it was changed, just need to know who/what changed it.
The system uses NTP to sync the time, but it is also possible for anyone/any application to change the time(for eg: using the simple "date" command as well).

I have a large CSV file, tab-delimited with CRLF at the end of each line. Each line should contain 5 fields (i.e. NF == 5) However, there are rogue CRLF characters in the middle of some records, causing records to be split across two lines. I want to scan each line, check the field count and if it's !=5 then join that line to the following line. Example input might be;

I've got a website set up which has a section which is just a bunch of links on the side. But this section of links is on every page of the website. And when I expand and add more links I don't want to have to go to every page and add the new link. Is there a way that I could put all the links into something on CSS (or anything else) that I could just include one line in the HTML? So that when I add a link I'll only have to edit the one file and and then every page will be updated?

will add one more line :

View 5 Replies View RelatedI have a file witch I need to list 10 line by 10 lines with something like press enter to go on in between.
Well, the problem is that i have absolutely no idea on how to implement this.
Can you give me some points?
I have a CDL netlist with 5630 lines. 512 of the lines are over 128 characters. The tool I am using to read in the CDL returns an error for each line over 128 characters.
If the line is too long I can fix it by adding a line continuation symbol, in this case a "/", somewhere prior to the 128th character then a line feed, obviously, and a "+" to the continuation.
example (pretend its a long line);
before;
this line is too long
after;
this line /
+ is too long
Part of the problem is that I can't use a constant point prior to the 128th character because I can't break up a term.
bad;
this line i /
+ s too long
If I can replace the last space before the 128th character with " / + " on all lines that are over 128 characters then I'm golden. I'm not sure if I need to escape the + or not. If so then the substitution is " / + ". And if I use sed then I'll escape the .
So For example I run this command:
Code:
But want to gerp / cut it in such a way that it only displays
Code:
Now the thing is that these 3 lines are not static.. there can be N number of lines there.. the only thing is that I want the command / output NOT to display the first line but the rest of the n lines ..
I'm trying to find the correct sed syntax to match from a given pattern to the end of the file and then append that pattern to the end of the file.
I was trying:
But that prints each line right after its original occurrence. I want to match the block and then append it to the end of the file.
