CentOS 5 :: Tool To Standardize All .jpg Sizes And Make Them Smaller In Size
Jul 4, 2010
If I open my 3.3MB .jpg file in Microsoft Paint and re-save it as .jpg it will right away loose it's size and go down to 1.5MB and still keep the good quality.
I have 100s of these picture files, so I can't set down and do it one by one in Paint.
I am wondering if there is any command in Centos 5.4 or tool that I can use to not only make these files size smaller but also to standardize their size to let's say 800 X 600. The latter is not really needed but it will be bonus if someone can guide me.
I am running a php photo gallery script and it takes way to long to load the picture hence the requirement to lower the size for all the files.
I know that there is "mogrify" and "convert" but I think they don't work without GIMP. I don't have GIMP installed and I do install it I think it goes on to install a lot of gnome libraries which I am afraid might break my server or overload it too much. My CentOS doens't have any GUI or gnome package to it and I want to keep it simple.

Does anyone know of a way to make the hulu screen size smaller? The smallest that I can get it is still taking up about 1/4 of my screen.,

Each version of Ubuntu I've used, the size of the text in the virtual consoles (Am I allowed to call it "screen resolution" if it's a CLI?) has varies widely; some versions had the consoles in 80x24 text mode while others used much higher resolutions.this version of Ubuntu seems to use 80x24 characters, which looks really ugly on my 17" screen. Is there any way to make the font size smaller? QBASIC had a WIDTH command to change the number of rows and columns of characters,

Recently I installed some of the MS Office 2007 fonts onto my Ubuntu 10.10 machine in order to use them. Unfortunately, a few of them look really blocky at font sizes smaller than 16 pt. The two i'm having issues with are Calibri and Cambria. I don't seem to have this issue with any other set of fonts. Here is a screenshot of the issue in question. I remember having this same issue on 10.04, before I upgraded, if it means anything.
By the way, I took the fonts from a windows machine, on which the fonts were working properly.

I feel really stupid posting this, but I can't find what I am looking for. I feel like I have a decent understanding what is going on, but I am missing something very elementary. I have several mpc clientpro machines that are all in one's with 17" monitors built in. I can't get any resolution to fill the screen. I have been playing around with settings in xrandr, to no avail.
In windows xp it is usually ran at 1024x768 resolution which is supported. However there will be about 2 1/2 inches of blank space on the right side of the scree. and then another 2 1/2 inches of blank space on the bottom followed by about 2" of what seems to be a mirror of the top 2". I can change to several different resolutions all taking up different sizes of the screen, but nothing will fill it.
I understand I can't just do anything I like, like it would be unreasonable to expect the card to output 1920x1080. But can't I get it to at least fit the screen? Whether it was 1024x768 or 1152x864 or 800x600.
I have been searching and searching, and I think I am just simply misunderstanding a key term that is not allowing me to find more information on this. Something like panning, overscan, etc.

I'm looking for some suggestions to create smaller size video files with the following equipment: Logitech Webcam C200 (USB), 640 x 480 resolution, 30 fps, using guvcview software. I'm new to doing video and wish to make short, up to 10 minute, clips. The above configuration puts out only .avi files and those files are huge. One small 30 second clip will cost 30 to 35 MB.
I have a friend using a Flip video camera putting out 30 second clips at 3 or 4 MB tops and the video quality is head over heels better than mine. His Flip system puts out MPEG-4(mp4) files. Other than buying a Flip video cam is there any way I can produce smaller file sizes? Maybe better quality too?

I am looking for a utility that would do the following:1. Be run manually on a list of files whose sizes should not change, to get a control file containing the sizes of each file.2. Subsequent manual runs would report any changes in size of any of the files in the list, and allow option to accept the new sizes.3. Be run as a cron job to check for changes in the file sizes and send an email alert if a change has occurred since the last time it was run.The purpose is to detect possible hacks of key files on a website. It would not include files expected to change, but just those that should not change. It would be run manually a few times to get the control list one wants to monitor.

I have been using Debian on and off since Sarge and it's not as long as most people but since I can remember, the installer has always had some issues and I was wondering if you guys who use Debian religiously could answer these questions for me:
1. Difference between "Netinst" & "Business-card" besides the size being smaller? It seems like the Netinst installs two different kernels. One dated kernel to get the system up and running and then it downloads the latest one where I think the 'Business-card' ISO simply downloads the latest kernel and nothing more which seems preferred. Am I wrong?
2. After I install using "Netinst", why when I immediately perform an 'apt-get dist-upgrade' are there multiple packages to upgrade? I thought the whole point was to install fresh updated packages, no?
3. Why has nobody fixed the installer progress bar from hanging on 33%? As far as I have been using / installing Debian, the installer progress bar is always stuck on 33% & it still installs fine but never shows the user it's exact progress. I would think the developers would have resolved this after 4 years by now...

I am using OS 11.0 Every time I boot my laptop (dell inspiron 9300 - ati video M300). I get the desktop display as 1920 X 1200. This is too large for my default. I use KRandRTray to resize back to 1024 X 768. How can I set 1024 X 768 as the default but still have the option to go to 1920 X 1200?

I want to set my editor's font as Monaco-11, but it has no anti-aliasing effect. And when I set it to Monaco-12, anti-aliasing effect works. How can I make it also work for Monaco-11? I'm using Ubuntu 9.10

this might be a silly question, it might not. I need to send upload some documents (scans) I have onto a website, and there is a limit to how large the pdf can be. (7MB) The file I have - and I can upload only one - is about 10 MB. Is there any command with which I can make this pdf smaller without compromising the resolution too much

I have a rack of four 1TB drives all partitioned identically with three primary partitions. On each drive
- the first partition is only 64MB;
- the second is a large 900GB partition and
- the last holds all the remaining space
mdadm has been used to set up
/dev/md0 - RAID1, comprised of /dev/sda1 and /dev/sdb1
/dev/md1 - RAID5, comprised of /dev/sda2, /dev/sdb2, /dev/sdc2, /dev/sdd2
/dev/md2 - RAID5, comprised of /dev/sda3, /dev/sdb3, /dev/sdc3, /dev/sdd3
OK, so it was a silly mistake to make - but I am now need to increase the size of /dev/md0. My thinking is to reduce the size of md1 so that I can grow md0.
On md1 I have two logical volumes. I've successfully reduced the size of the volume so that I can reduce the size of md1. Now I'm at the nervous stage; I can find little written on the topic of shrinking RAID5 arrays - and even if I do this I'm unsure if I can move partitions around to regain the space I so desire.

I've noticed this issue for a long time now, and it's always bothered me. Whenever I have to open a file within a program or upload something to a website, etc., the window that pops up is always HUGE. The reason is due to the list of file types at the bottom. Instead of cutting off with an ellipsis at some point, every single applicable file type is listed. I can't resize these windows, either, so they always take up my entire screen. Is there any way to fix this so that these kinds of windows are a more reasonable size?

I just upgraded from Ubuntu 10.10 to 11.04. I am still adapting to it but. Can I make this dock smaller? It is TOO big. I can't fit more than a few icons there. Also, I am a little lost. Where is the menu? I can't find system settings. How do I edit launchers on Dock? What command do I have to use in order to restart the panels? (on 10.10 I was just killing the gnome panel and it restarts by itself)

I want to modify and make smaller changes in a PDF document. How do I do that in Ubuntu?? I have heard it is possible with Open Office when you have some extensions to it? I have tried PDF Mod but you can't make much with it. I need to change text inside the document.

I am trying to clone the hard drive to a slightly smaller hard drive in the same computer, same setup.What software or commands do you use to clone the entire system and resize the partition automatically?The original HD is a little larger than the destination HD. The source partition only has about 20 GB in use and the rest is blank.
I have 2 partition, a small 100MB boot partition and another 500GB LVM partition.I can't just clone from the original disk to the new disk. (for another long reason) I need to make an image of the original disk on an external USB drive first, then move that image onto a new disk.I have tried creating an image of the whole disk with Clonezilla, but then the restoration didn't work because the target drive is smaller than the original.

Been using Ubuntu 9.04 for a while now but I've always felt that the interface is too chunky. The buttons, text, dialogs are waaaay too big. Is there any good solution to reducing the size of everything, including dialogs and buttons. So far, I have been dropping the DPI with mixed results. It mostly affects fonts so it hasn't fully met my needs.Hence, I am posting on here to see how other people manage the chuny-ness of Ubuntu. Have you just gotten used to it? Have you got your own workaround? Have you converted to kUbuntu!?

I have a dual-boot Vaio, with Windows Vista (for WOW only,I promise!) and Ubuntu 10.10. I have a HDD with 250 GB, where 170GB is for Ubuntu and around 40 GB for Windows and a Swap that is 6 GB. This Swap seems a little too big, so how o I edit its size (make it smaller like 3GB) and then add the "free space"-leftovers to the big Ubuntu partition ( / )?

I think 32 pixels is still very big for a launcher, can I shrink them more somehow in Unity? I'm talking about Ubuntu 11.04, of course.

After doing an update a couple of days ago (had previously upgraded to 5.6), the font size in firefox (file forward reload, etc), terminal and the panel (using xfce) are significately smaller. Searching the web, mail lists and the forums have not resulted in finding anyone else with this problem. I did notice that glibc has a bug that is currently being worked on at Redhat but it is unclear if the font problem I am seeing is related. Note also, that the initial upgrade to Centos 5.6 was successful.

I am using 10.04 LTS Lucid, and I notice the free space of root is getting smaller and smaller.
Five months ago, there was about 3.9GB free space of root, but now it is only 1.6GB. I always run sudo apt-get autoremove and sudo apt-get autoclean every time the update is finished, and also use Bleachbit to clean the system, but both are useless.
I never faced such problem with older versions of Ubuntu, is there any measure to fix it?

I have a volume group that is made up of a number of physical volumes. I am thinking of consolidating all the small physical volumes onto one big drive. Is there any benefit in this, besides making administration easier? How do I go about doing this? From what I have read, it looks like I should have to do the following
1. add the new big drive to the VG
2. use pvmove to move the smaller PV onto the new PV
3. use pvchange -xn to make sure the old PV can no longer be allocated
4. repeat for all the small PVs.
5. use pvremove to remove all the small PVs
Is this the correct procudure to follow?

I need write a script that can compare multiple input files and output a file. The basic idea is:1: All my input files are in the same format2: I want to find in-common lines (in-common 1) from some of my input files (e.g., input1, 2 an 3), and find in-common lines (in-common 2) from the rest of my input files (e.g., input 4,5,6,7). And then, compare in-common1 and in-common2 and remove any overlap from in-common 1.3: Output the remaining in-common 1 file after removing any of its overlap with in-common 2I know how to write this script by putting all the filenames in one script and compare them. But the thing is, if I have more input files, such as 100, it might not be that efficient to write all filenames in one script and compare them.
I am wondering if there is any way to do such as:1: put all input filenames in a text file (file1)2: write a script3: Everytime, when I run this script, it will read in file1 directly no matter how many input files I have, give an output.I want this because I will have more and more input files and I don't wanna add multiple lines in the script just for reading the new inputfiles and compare them with the previous files. So, I guess this is something related to making my script a package or standardize it and make it easy to use in the future no matter how many input files I will have.

1. There is not any .deb in the /var/cache/apt/archives.
2. The total content of /var/log is only 167.6 MB, that won't be a problem.
