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:
for line in $(cat tmpSearch)
do
line=`echo $line | tr ":" " "`

I tried googling around but i cant find anything related to this: everyone seems just interested in random numbers, so when it comes to random letters there is a lack of informations. However, i am trying to figure out a wait to get a random letters string that matches a simple rule: it must be a sequence of consonant+vowel. So for example, these are some 6 letters strings i would like to obtain: wolupa, tafoke, zewevu, cupimo.

View 3 Replies View RelatedI have a filename file-name-here-1.2.3-i486-2.tar I would like to know how to remove the last two fields leaving only: file-name-here-1.2.3

echo ${a%-*}
to remove the last field (after -) but how do i remove the last two in one fell swoop?
The lines beginning with greater-than symbols are the sequence descriptors and the lines immediately after each descriptor with A-Z characters, dashes, and question marks are the aligned DNA sequences. The sequences are always the same length within a file and never span/wrap across more than one line.I am trying to write a script to remove positions in the sequences that are only represented by a -, X, ?, or N (these represent gaps or missing data). Also, if there is exactly one non-gap/missing character in a position it is also useless (there is nothing to compare it to) so I would like to remove those positions as well.
Position 5 (from the left) was removed because it was all gap/missing characters. Position 9 was removed because only one character was a non-gap/missing character. Position 10 was retained because there were 2 non-gap/missing characters.I'm really not sure where to start here. My first concern is I can't figure out how to tell awk to treat each character in lines not containing a greater-than symbol as a separate field. After that, I'm thinking I should use set up a counter to count the number of lines with gap/missing characters comparing that to the total number of lines not containing greater-than signs?

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.

Unfortunatelly since i have no background at all about GUI programming, i dont know even the keyword for that i want to generate a pop up window from my program (written in C) which show a message and an OK button. in my opinion, maybe i should use directly the Xlib library and not the GTK or QT library for example so the program can work almost on every linux system.

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.

I know how to manually writing a makefile for my project, but I am new in using makefile & configure file generation tools like automake to generate a makefile and a configure script file.
I had done research on tutorials for generating makefile and configure script file.
I know that I need to manually write two files (makefile.am and configure.in).
I use wxWidgets GUI library, libconfig library, and libpcap library to do my project.
wx-config is a tool that can return the library files and include directory for wxWidgets library.

How to add that line to the makefile.am file?
I am running some muti-threaded code that uses a lot of memory (~6GB). I have it compiled on a cluster that uses Xeon 5160 quad core CPUs with 4MB cache/core, 8GB of RAM and kernel 2.6.18 (x86_64) and I have also the same code compiled on another cluster that uses Opteron 2214 quad core CPUs with 1MB cache/core, 8GB of RAM and kernel 2.6.28 (x86_64). On the Intel cluster the code generates barely any system load when I look on top but on the AMD cluster it can generate over 50% of system load. On the intel machines my process can generate a constant load of 3, while the load generated by the process on the AMD machines is about 1.6.
Does anybody know what could cause this? Could it be the version of the kernel or the difference between the CPUs (for example, the much smaller cache of the AMD CPUS)? My software and all its dependencies are the same on both clusters. I am also using the exact same version of GCC to compile everything.
I am trying to write a loop to open four main-data-files. At each open of the main-data-file, I want the loop to open another four sub-files and split the data from the mail-data-file according to the creteria and dump into the four files. When the loop goes to the second main-data-file, it shall generate another 4 sub-files with different file name. And the process goes on. That means I will have total of 16 sub files for the four main-data-files. Each four files from the 16 files shall have specific name on it. Based on the code which I given below, I would say when the file at UNIT=100 is opened, 4 new files needed to be opened as well. They are:
maximum_dist_001_064.dat
maximum_dist_065_128.dat
maximum_dist_129_192.dat
maximum_dist_193_256.dat
Is it possible to generate keyboard event "Ctrl+c" from a shell script code.? I have written a shell script to compile my application and copy it to the server home directory, inorder to run my application I need to start the server (by running a shell script). But before that I need to stop the the currently running instance of my server. To do that I have to generate a keyboard event (Ctrl+c which I press it manually). I want to automate the entire process by writing a shell script I am able to run the server just by adding ./run.sh in my shell script. But before that to stop my server can I generate a keyboard by using a shell script event(ctrL+C) to stop server.?

I 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!
[code]....
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!
