I have a text file from which i read a number of names with their lengths at the run-time.Now i want to created a char array having the length and name as already read from the text file at the run-time. There is no compilation involved. Every thing is happening at the run-time. I tried using STL like map along with malloc but i am unable to name an array at run-time. I can keep some type of mapping with previously created arrays
I have a NETGEAR ReadyNAS NV+ with four 1TB drives in a RAID-5 array. This is our primary file storage. This has previously been backed up to a hardware RAID-0 array directly attached to our Windows server. The capacity of this backup array is no longer sufficient. So the plan was, take a bunch of 200GB to 320GB drives (And a 750) I had kicking around, chuck them in a couple of old SCSI drive enclosures I have collecting dust, attach them via IDA/SATA-to-USB adaptors to a USB hub, attach that to the server, create a JBOD array spanning the disks, and back up the NAS to that. Performance is not an issue as this is just to be used for backup, with the idea being as near to zero cost as possible (Spend so far = NZ$100�ish).
The first hurdle I struck was Windows not supporting Dynamic Disks on USB drives (Required to create a spanned volume). At first I resisted using another machine (i.e. a machine running Ubuntu) as I didn't want to dedicate a piece of hardware to backing up the NAS. I then decided it would be acceptable to do this via a VM, which is what I've done.So I have 10.04 running under VMWare Server 2.0.2 under Windows Server 2008 R2. The disks are all presented to the VM. I wasn't sure if I was going to end up creating the array under LVM or something else, but I noticed Disk Utility has an option to create an array, so I tried that. When I add two 250GB drives, the array size is 500GB. When I then add a 160GB drive, the array size drops to 480GB. Huh? If I keep adding disks (Regardless of order) the final array size comes out at 1.8 TB, as per the attached screenshot. Now with the following drives, I expected something more like:
I need a process A to be able to get the start time of process B. I have the PID of the process B.
I would have thought there would be a simple system call to make by passing in the pid of Process B, but I don't thing there is??!!
So my other thought is to create a script that will be passed the pid and either I can read the file creation of /proc/<PID>/stat or I could also parse the start time of ps on the <PID>. This script can be ran from the C++ code. My difficulty is capturing this information in the C++ code. If I run exec ( or system if not a script) I need the results in a program variable....not stdout.
My only solution is write it to a tmp file and read it back into the program variable. Seems rather arguious but a least it would work.
Background - I need to port Windows code ( GetProcessTimes(creationtime,...))
How I can tell tar to assign a new creation date to extracted files? Let's say I have an archive filled with old files of varying ages. Upon extraction I want all files to have the same time stamp (that of the time of the extraction).
I was wondering if there is a command to show a real-time creation of files. I basically executed a command that will created thousands of files and takes a long time. I want to check if it is still creating additional files or if ti got frozen.
I know newer filesystems support crtime values, even to nanoseconds granularity. Ext4 does it, and NTFS mounted via ntfs-3g should expose it. Still, what is the command to get these values??
getfattr -d <some file>
gives me zero results, and as far as I know ls does not have means to access creation time.
getfattr -n ntfs_crtime /mnt/<some ntfs fs> gives me "Operation not opermitted"..?
I know about the difference between ctime=inode change time and crtime=creation time/file birth time. I want to migrate a NTFS partition to Ext4 without losing the creation dates...
I'm writing a PHP program. I've encountered a problem; in the following code I try to pass $_POST['delete'] which is an array as the value of a hidden input to some form, but it doesn't do so.there's something wrong with converting PHP array into HTML array. I'm sure that $_POST['delete'] is not null and is a real array.
When I am creating a user (say sandy) on my FC14 system, I find that the default permissions for her home directory (/home/sandy) are 700.Can I somehow set up my system so that these permissions are 711 in place of 700.
(I am using vector() and matrix() functions from "Numerical recipes in C".)There are 100 numbers to be stored in 2D array of 10 rows and 10 columns.100 numbers are stored in a 1D array.I get "segmentation fault" at the line indicated in the segment of my code below:
I looked on the net for such function or example and didin't find anything, thus after having made one i guess it would be legitimate to drop it to see what others thinks of it.
#!/bin/bash addelementtoarray() { local arrayname=$1
I've been running 10.04 since September on my new MSi i3 notebook and about two weeks ago I noticed that when I login after system boot, propagation of icons on my desktop and the content of my Panel have become slower and slower.If I logout and login again the propagations are not slow.
I'm installing my first new Dell SCSI controller card (PERC 6) and storage array (MD1000) into my first RHEL server. I've done this plenty of times in a Windows world, but never in Linux. I know the BIOS will pick up the SCSI card and I can go into that during the boot screen to set up how i want the array (RAID5), but once Linux comes up, will it automatically find and mount the drives, or do I have to do something?
I am going to be creating some graph representations of neural networks for my thesis. I am trying to find a good method for drawing them, preferably in a scripting manner. I like NetworkX since I know python, but am also curious about GraphViz (though the documentation is sparse) or any other solutions anyone may know of. It is important that there is a decent ability to interface with LaTeX.
I'm trying to get a password in a bash script for mysql user creation. But sometimes a get a non-alphanumeric character(s) in the password, and mysql failes with that. I tryed with apg -EO0Il1`~!@#$%^&*()_+-=[];./{}|:"'<>? but failed. I tryed with sed 's/[^a-zA-Z2-9]//g' , but at that moment the minimum password lenght failed. I'm also fine when there is a better alternative then apg.
I'm new to UNIX scripting; I�m stuck with the following I have an Oracle SQL script that takes three parameters
1- File Name 2- File Path 3- File creation date
Under UNIX I have a folder where files will be placed frequently and I need to upload those files to Oracle, what I need is a UNIX script that can do the following
Loop through Directory "/home/applmgr/snktmp" Picks only files Pass the file name to parameter &1
[code]....
Is the above possible? I already knows how to call the Oracle Script from UNIX Im only stuck on writing the UNIX part where it List the files attribute(name,path,date) and store them to parameters ,Looping until the last file in the directory If the above is not possible,then how can I create the below from the command line
I am using Debian linux. I have 100 timers running. If a timer expired which will generate a signal and it was mapped to a same function handler. All the timers are mapped to one function handler. The problem is if the timer expires one at a time, the function handler called at a time. But if the 2 timers expires at a time, the function handler is called one time only instead 2 times. Is it possible to invoke the function handler as many times based on timer expirary happens simultaneoulsy?
I am trying to set time using settimeofday in linux. But it sets local time. i.e works like SetLocalTime in windows. But I want to set system time(like SetSystemTime in windows). I could'nt find no other api in linux. What should i do? I had tried with mktime/gmtime apis
This array is supposed to contain 12 elements (names of the month) What I want to achieve is that depending on some user input (a number 1-12) a full name of one of the months will be displayed, eg.
Code: scanf("%d", &month); printf("The month is %c", months_names[month]);
