Hi,

I am planning to tweak the exising GPM mouse driver for Linux. Can someone please tell me whether there is a good tutorial on it available?

Abhishek

I could. But then
(1) I need to modify the regexp I am now using to catch one such occurence (it catches 2 occurences now). For every loop I need to chop off the part of the string I have already...

Hi,

I want to extract some part of a pattern that matches my requirement in a string with PERL. A case in point is a string like:
$eqtst="abh nmae res = 10 s abh nmae req = 10 s";
from which I...

First of all, thanks for the response.

The order of my matrix is curently 2000 X 1000....but it might increase over time. Is there a possibility of memory overflow? This is one reason why I didnt...

I have a m X n matrix written out to file, say like this:

1,2,3,4,5,6
2,6,3,10,34,67
1,45,6,7,8,8

I want to calculate the column averages in the MINIMUM amount of code or processing possible....

Here's an oneliner:

awk -v x=$a 'END{if(x==x+0) print "integer"}' /dev/null



In this example , a is shell variable.
If a=10, then the output of above is "integer"
If a="10abhishek", then...

Sorry...the corrected code is (missed the conditional in the for loop):
awk 'BEGIN{FS=":"}{str=""; for(j=1;j<=NF;++j) if(j!=4) str=sprintf("%s%s",str,$j)}...

Hi,

I made small change to the code posted by Ygor...and that will apply to solution by Aigles too (remember, my problem is reassigning $4 doesnt modify $0). Heres the changed code:

awk...

there is a slight problem i am encountering.......

reassigning $4, does not reassign $0. So both of the above methods are failing....any cures?

You are a man of few words :D ! Amazing!
My unix machine is down, and it will be a while before I can try this out. But now that I have seen it, I can tweak it, if I do run into any errors.

Hi,

I had a similar requirement sometime back. Check up the 'join' command in UNIX. The idea is to join (join as in a table-join in relational databases) the files using the first column and...

Hi,
I have the following 'sorting' problem.
Given the input file:


a:b:c:12:x:k
s:m:d:8:z:m
a:b:c:1:x:k
p:q:r:23:y:m
a:b:c:3:x:k
p:q:r:1:y:m

the output I expect is:

a:b:c:1:x:k...

Hi,
This thread was started when I found an error that I wrongly attributed to buffer overrun in PERL. I found the bug recently, and thought would mention it for future reference. The progressive...

Thanks cbkihong! I will see what I can do with your advice. I will post a solution here if I find anything worthwhile, within this week (I intend to upgrade to FC5 by next week anyway)

I am unable to get any sound in my Linux installation, which is Fedora Core 3 on a Intel D915GAVL mobo. I tried to look for similar problems on the net :( but most have their solutions in modifying...

Actually I rewrote the parts where I am assigning the contents of a file to an array ( now processing the contents with a while (<FILEHANDLE>) , but the error still occurs ), but I sure missed the...

I dont know whether this is a common error but it seems my PERL program is running out of buffer memory. Inside a loop I am processing an array (reading elements and displaying in it--note: for...

I am not sure if this is the right place to post this. Heres my problem: When I posted yesterday I think I saw the number of posts made by me as above 60. Today morning when I posted, it showed my...

I am providing a possible solution thats three lines long. But if you explore the 'join' command in unix, I am sure you would work out shorter versions:

Let your first file be a.txt, and your...

Heres to your "^M" error:

https://www.unix.com/showthread.php?t=25936

"." runs the script in current shell, as you said. The reason for doing this is we want B.sh to recognise the variable "var"(which can only be recognised in the shell that it was defined in)

If...

I am not very clear about the requirement (and not good at sort too). But see if this helps:
$ awk -F" C" '{print $2"."$0}' sortfile|sed 's/DBSU/\./'|sort -n -t '.' -k +1 +
2 -3 +3 -4 +4 -5 +5|cut...
