General :: Grab A Random Section In The Middle Of A Huge File?
Apr 23, 2011I have a huge log file of around 3.5 GB and would like to sample random sections in the middle of say 10 MB for the purpose of debugging what my application is doing.
I could use head or tail commands to get the beginning or end of the file, how can I grab an arbitrary portion from the middle of the file? I guess I could do something like head -n 1.75GB | tail -n 10MB but that seems clumsy and I'd need to determine line numbers for the midpoint of the file to get 1.75GB and 10MB line counts.

View 2 Replies View RelatedOpenSUSE Install :: Immutable Section Of HDD + Differencing Section?
Jul 8, 2010You maybe know that VirtualBox has an "immutable" feature for HDD images. I.e. setup the system, if the stuff is in place, you can set the image to IMMUTABLE to prevent any changes to the image. Differences are written to a separated image. So on the next boot you'll see that all the (unintended) changes are gone and the "old" system is up & running again. I run an old SuSE 10.3 on a write-protected SD-IDE-Adapter. Changing and playing with RPMs is a mess due to around 50 changes I had to do to make that work. Is there any option to mount an SD-card as RO and having all the changes written to e.g. /dev/sda3? To make it clear: I thought about something like a RAID-X system, but could not find any description on how to setup a raidtab.

General :: Remove A File On System Using Inode Number?
May 19, 2010If you create a file on UNIX/linux with special chars, like touch "la*, you can't remove it with rm "la*. You have to use the inode number(you can if you add the before the name, I know, but you'd have to guess as a user that it was used in the file creation).
I checked the manpage for rm, but there's no metion of the inode number. Doing rm inodenumber doesn't work either.
What is the command for this?
General :: Remove Background Layer Of Djvu File?
Jan 11, 2011I've downloaded some files from the Internet Archive. They come in different file formats and most of the time I use pdf. However, sometimes the scans are saves in colour instead of b/w. This makes it difficult/impossible to read on a dedicated ebook reader. In that case I downloaded the djvu files as on the PC you can select which layer (color, bw,fore,back) one would like to see. Selecting the bw gives excellent results. However, the ebook reader does not has this option.
The question is, how can I remove /extract a layer from the djvu file and save only this layer.
So far I've tried the following two approaches:
1) select bw in the djvu viewer on the PC and printed to postscript file. Followed by a ps2pdf conversion. This works, but generates a fairly large pdf file. Sure, I can again upload it to any2djvu but it just seems to much manual work for each file.
2) I tried the shared annotation feature and said (mode bw). This works on the PC as desired but is ignored on the ebook reader as the other layers are still present.
