I have a zenity message box in a script
zenity --info --text='done' > /dev/null 2>&1
I need to pop up a message, e.g.: "file is smaller then 30 KBytes!" when a file is smaller then 30 KBytes. How could i write an "if then else" script to pop up a zenity message, when e.g.: "FILE" is smaller then 30 KByte?
How can I make ls (or any other particular command) to list me only files bigger than a specific file size?

Using Ubuntu/Fedora
I am trying to output md5 or sha1 along with fullpath/filename and file size but I dont seem to find a way to do this.
with
Quote:
find . -printf '%s %p'
i can retrieve size and fullpath and filename
however I am not able to merge that info with the md5 or sha1 of the file
my aim is to have a file such as this
6435b607f86b6e6be1e77bb3b1987677d1377275 ./abc/asda/file1.txt 404
6435b607f86b6e6be1e77bb3b987677d13772725 ./abc/asda/file2.txt 1404
also, performance is an issue for me, since i need to get the info out of 10m files (approx 6TB), so commands like find are preferred and less iterations among commands would be great too.
btw i've tried to use something like this
Quote:
find . -type f -printf '%s %p'| xargs awk '{x=system("md5sum "$2)}END {print x" "$2" "$1}'
but variable x contains the return value of the system command md5sum and not the stdout
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?

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.
i'd like to know the total filesize of all files found with the find command, so
Code:
find -iname '*.mpg' | xargs -I {} du -sh {}
but this gives me the filesize of each file, since each line is passed to "du".
how can I pass the whole list through the pipe?
I ordered a new laptop which has a conventional hd with the pre-intalled os on it. I would like to make an image of all the software that is installed on this conventional hd and move it to an ssd which I will use to replace the hd. Problem is that the conventional hd is 320GB and the ssd is only 240GB. All solutions I've found require the target partition to be at least as large as the source.Is there any way of doing this using linux?

View 1 Replies View RelatedIn a few hours I'll have a new 500GB Sony laptop, filled with the usual Sony rubbish which I'll promptly be replacing with Ubuntu or Crunchbang or something. However, first I want to make a full clone of the drive (including recovery partitions), should I wish to return it to Sony or sell it on in its factory state.
The problem is that the only backup drives I have are less than 500GB - the biggest I have is 250GB or so! So I need to backup and compress on-the-fly.
What's the best way to do this? Presumably dd piped into gzip would do the trick, or does anyone have any other suggestions to accomplish this?

I need to clone a 160GB hard drive with Linux Mint 9 (not more than 10GB used) to a 30GB SSD that is partitioned carefully (aligned to cylinder boundaries) and is currently running Ubuntu (which I wish to overwrite with Linux Mint 9). The SSD has a /boot partition, / and swap. The source (160 GB) does not have a separate boot partition. Can anyone help me fill in the steps below? /dev/sdc will be the source (160GB) and /dev/sda is the target (with partitions 1,2 and swap on 5).
make a copy of /etc/fstab from the target drive before proceeding. Ready the target partitions. Can I reuse the existing destination partitions on the SSD? Ready the filesystems on each of the target partitions. /boot is ext2, / is ext4 and swap is already set up too. As I said, all contain data (Ubuntu) that I wish to overwrite. So what steps are needed here? Do I need to erase anything (files, etc.) before the copy/clone? next, use dd to copy MBR (right?) And exclude partition table:
Code:
dd if=/dev/sdc1 of=/dev/sda1 count=1 bs=446
Mount the source and destination drives:
Code:
mount -t ext4 /dev/sdc1 /mnt/source
mount -t ext2 /dev/sda1 /mnt/boot_target
mount -t ext4 /dev/sda2 /mnt/root_target
I suppose I can leave the swap partition on the target untouched. Copy the files from the source partition to the destination
Code:
cp -a /mnt/source/boot /mnt/boot_target
cp -a /mnt/source/ /mnt/root_target
then I assume I go to /mnt/root_target and delete the /boot directory, right? Change /etc/fstab to reflect the new partitions. I mount by label. Will my partition labels be intact after this? Do I have to make any changes to GRUB? Anything else?
I'm looking for a way to compress a large file (~10GB) into several files that wont exceed 150MB each.

Tool like Media File Segmenter for Linux
I know that one can use ffmpeg to extract a smallfile.avi from a largfile.avi. But What I am looking for is an tool/command to split a large file into several files of a given size.
I've decided that I want to use another, smaller, hard drive for my OS and I'd like to clone /dev/sda onto /dev/sdc. I want it to be an exact clone except my partition for my "/home" will be smaller (since there's not room for it). I was gonna try with dd but I'm not sure if I should build the partition table and use dd-command on one partition at the time? Will this then include GRUB boot loader and will it be working properly?
Do I have to clone the disk completely for it to boot properly? I'm not sure how or where GRUB places itself on disks as you install it. Can I perhaps copy the partitions one by one and then install GRUB from CD afterwards? Should I leave some unallocated space somewhere in between the partitions as I build and clone them?

I have a Logitech ambidextrous trackball, with a left and right mouse button. The trackball device also has two smaller left and right buttons. I'd like to know how those two smaller buttons are addressed. Ultimately, I'd like to assign certain keystrokes to them, to make work faster. For example, ALT+<right arrow> moves a browser back one page. how to name these keys, or whether/how I should address this USB mouse. FWIW, I'm actually using it through the PS/2 mouse adapter, since that doesn't take a USB slot.

View 1 Replies View RelatedI got a new hard disk for my laptop and I want to move my Gentoo installation from old HDD to new.
Most simple guides recommend use of dd to copy the whole partition byte by byte.
I'm moving to the new drive because I don't have enough space on the old drive, so I don't want to simply clone the partition. Instead I need the destination partition to be bigger. Would dd work well in that case?
Assuming that I use same partition types on the new drive, would I be able to use simple cp with appropriate settings?
I cannot reduce the size of all icons, context menu items etc.For example, I need to do some minor programming for the university. And this is how Eclipse Aptana RadRails look on a netbook: [URL] UI takes up to 70% of screen space, and the IDE is barely usable now. On Windows it looks like [URL] I tried some gnome themes but they all are of the same size. Is there any way how I can reduce the size at least for the whole system (nautilus etc)? If there is a way how I can apply 'nanoized' theming for desired applications only.

View 5 Replies View RelatedMy parents bought a new hard drive for a laptop that I've owned for several years. It's much larger than the current one, so I plan on splitting it up to dual boot it with Ubuntu.I have no problem with partitioning a drive (I always keep a LiveCD handy), but my question is this: how can I go about moving the existing partition to the new drive? This is a laptop, so I can't simply plug the new drive into another slot.
Also, even if I manage to move it, will Windows still work on the new drive in a larger partition? I've had this laptop for quite a while, and I've lost the recovery discs that came with it a long time ago. I also have a lot of software without CDs to reinstall them with. This makes not reinstalling Windows a high priority.
I have an ISO of a game I own that shows up as 5gb. When I mount the ISO like this:
mount -t iso9660 -loop game.iso /mnt/loop
and go to /mnt/loop and execute
du -hs
it returns 2.5gb. Examination of all the files and directories in /mnt/loop does indeed add up to 2.5gb. So my question is what happened to the rest of it? Does the 5gb ISO contain a bunch of empty space? Should I try to burn it to a DVD and see what happens or should I burn it to a dual layer disc? I don't want to waste a dual layer disc if I don't have to.
