Red Hat / Fedora :: Make Constraints On Size Of Any File?
Jun 23, 2011
If I have a file in which data is written which leads to the increase of this file size
Is it possible to make a constraint such that this file size mustn't exceed certain size
let say 5 MB for instance
I notice that when you try to Make link to any file or folder form context menu, It just copy the same file size? even when i tried to copy the link to external storage disk..
is lvresize with --resizefs options re-size the Logical Volume and then re-size the file system? i mean we don't need to use resize2fs?I looked at man pages but it doesn't explain this option.
Is their a command I could use to do this? It needs to be 32MB (33,554,432 bytes), can be either random data or just a blank file, though random data would be preferable, and well... that's it.
Though also, is their a way I could copy the file in a terminal and it print out the info such as average speed and/or total time it took to complete. I'm trying to fight some bad reviews on this flash drive I bought that performs very well, and since stupid comment vs stupid comment doesn't win anything I need to apparently be the first to actually test this drive throughly.
This may seem to be a silly question, but I googled along and found that most of relevant complaints was about a bug in video card driver.
My problem is - For some unknown reason, I can't resize the Konsole window horizontally while I can still resize vertically. This is bad as the corrent width of Konsole window fills the entire screen!
I had to rename a table yesterday due to a contact / group name change in the office and sadly I'm the only person who knows how to barely interact with SQL due to my years as a Linux Administrator. Renaming the table was simple:
Code: iamunix=# ALTER TABLE accounts RENAME TO marketing; ALTER TABLE
At some point my wine install died. I haven't used it a lot and I update my Fedora 11 regularly so I'm not sure what made it break. I thought "ok, just see if there's an updated version". 'yum info wine' says there is an update version and the file is 27k in size. Tried installing and no joy. Tried erasing wine and then installing; no joy. Yum says that the X86-64 and the i686 version are both 27k in size. I know for sure that is wrong. On a semi-nonFedora note, I tried compiling my own version of wine. It compiled fine after installing some dependencies and '-devel' files, but it gets the same crash as the Fedora version was getting.
I'm all new to linux. I've got Fedora core 12 - I'm ex windows user. I have these 3 websites to maintain: These are in finnish language. So called pikalaina sites: pikalainat pikavipit vipit
And I have to add pictures to these pages. I don't know how to do even that I don't know web programming or HTML. But my images are about 1 mb in file size - I use to have windows and photoshop and there is this save for web feature where file size is reduced.I have this GIMP -program now - it's terrible compared to photoshop, but it's free. In GIMP there is no feature how to reduce file size for ex. 1mb to 20 Kb. How do I do this? Do you know any good program to do it?
Can anyone tell me how to increase system file's partition size.I have ext3 type partition where FC11 is installed.Is it possible to increase the size of ext3 without lost of data?
Recently I decided to utilize an IDS system. So I installed Open Source Tripwire. Not that I am too worried about anyone gaining a successful foothold on my system. But I wanted to learn and experience this IDS system. And no, this is not a new server install but I have never seen anything that resembles illegal activity. My server is an installed CentOS 5.3 with SELinux in targeted mode.
Tripwire has brought to light some interesting things. Installation states to verify rpm packages using rpm -Va. I have found that many of my system binaries are not the same size as if I were to replace them via yum. Most of the binaries are like twice the size compared to a newly installed package, of the same version. I'm not sure what to make of this. These programs are the original installs (CentOS 5.1) and I keep the system up to date regularly via yum.
I wonder if perhaps these system files installed are perhaps different then individual package size installed via yum? I have a hard time believing this as a package is a package. The only other possibility that comes to mind is that nearly my entire system has been hacked with new system files, and in a way that has revealed and suggest nothing. I find that far fetched as I have run this server for some time now and I should think I would know a problem as not a morning goes by that I haven't review my logs, as they are emailed to me. Thoughts about the difference in file sizes? Those installed via CentOS DVD verses those installed via yum?
Fedora 12 gcc 4.4.1 I am doing some programming, and my program gave me a stack dump. However, there is no core file for me to examine.
So I did: Code: ulimit -c unlimited and got this error message:
Code: bash: ulimit: core file size: cannot modify limit: Operation not permitted I also tried setting ulimit to 50000 and still got the same error. The results of ulimit -a:
Code: $ ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited
i was using eclipse in windows 7, th fonts are small so I can see the code good. But I want to use in Ubuntu so I setup. But here the font size is huge and windows are taking more space and I am unable to code.How to reduce the overall font size and make it small?
When Installing Ubuntu what difference does the installation size make? Right now it's set at 17GB :/. The higher the install size better functionality or what?
I just installed Lubuntu 10.04 on old PC (CPU: 700 Mhz, RAM: 640 MB). My swap partition is only 474 MB. I was told it should be twice my RAM, if that's true then I'm really low on swap space. Can I expand my swap space? I also have Fedora 13 installed, it has a 1.3 GB swap partition, can I have Lubuntu use this partition?
I would like to make a backup file from my fedora 12, in case if I have any problem with it, I could restore all my programs and settings from OS, I used do this with northon ghost in windows, but now in linux I don't know for sure. Yesterday I made a backup, in the end it was 34gb of his size, I wanna backup only what is used, how I do this?
I have this directory with multiple images 'pics' and the size is 20mb and I want to make a .zip or .rar package of this directory but with an increased size so the .zip/.rar file will be 100mb, and then when you extract it the file size is the original 20mb. I want to make the result file bigger, no compress it. I need to put all the directory in one single file .zip or .rar but it has to weight more (100mb), maybe it can be done with another application. By the way, I have a centos 5 from command line.
I am curious if perhaps I am doing something wrong extracting pages from a pdf doc using pdftk and creating a new file. I am only extracting the odd pages from the file and outputting them to a new file that is now only 20 pages instead of the input's 40 pages, yet the new output file is still 1.4Mb in size, the same as the original.
It seems strange to extract only half the pages of a large document and end up with a result that is the same size. how to streamline the resulting pdf's using pdftk?
BTW this is the command I am using, in case perhaps I am missing an option to optimize file size or something:
I'm researching about symbolic links been used with samba / CIFS:I'd like that the user that uses a MS-Windows OS could see my shared folder on CentOS 5 and the symbolic links that are inside this folder. Well, it works but, the user will see that the size of the file is bigger than the real file. Apparently, CIFS gets the size of the symbolic link (aproxim.32K) and add it to the size of the file.Example 1: 100KB file, used with shared folder, MS-Windows's user will see 100KBExample 2: 100KB file, used with symbolic link inside a shared folder, MS-Windows's user will see 132KB. (Sym link + size of file)Is there a way to allow the user only see the size of the file, and not the file + symbolic links ?
I was just testing specifying limit on file size to a user and have added the following to /etc/security/limits.conf bob soft fsize 100 This basically should have said not to allow bob to create anyfile greater than 100Kb in size.
But the interesting thing is, if bob already has any file which is greater than 100Kb in size, it even doesn't allow to log him into the system both from console and SSH. Also nothing is logged in logs.. How do I configure it so that, bob can login to the system even though he has any file greater than 100Kb (but doesn't allow him to create file which are greater than 100Kb) ??
We have some large files with sampling data in it. Don't want to delete these files. But want to quickly overwrite the file with 0s and/or 1s and preserve the original file size.
