General :: Split A Directory Based On The Filename Prefix?

Mar 5, 2010

I have a very large directory with probably millions of small files in it. It's taking forever to run ls on the directory.

Is there an easy script that I can run to split the directory into smaller ones, based on the prefixes of the filenames. My goal is to wind up with something similar to what the Debian archives' pool directory looks like.

General :: Unexpected End Of File. Gzip Compressed File?

May 4, 2011

I am going crazy with a gzip file. I can decompress the file in Windows using WinRAR but it is impossible on any UNIX operating system. the file seems to be ok. If I do file the_name_of_the_file.gz

Ubuntu :: Sort Files Into Folders Based On Extension?

Sep 16, 2010

I recovered some 60,000 files with PhotoRec and need a script to sort them into individual folders based on extension. I was able to do this once before but cannot find the script again (sad thing is that I probably saved it on another HD that I'm having partition issues with, but that's another story....).I found this script:


mkdir "$1"
for file in *.$1; do
mv "$file" "$1"

While it does work, I am not looking forward to going through all 132 folders and typing in each extension. The last time I did it, the folder was automatically created based on the extension(s) found.

General :: Add A File Extension To A Bunch Of File Names?

Oct 20, 2010

I have a considerable number of files in a subdirectory (some fascinating old military clips from - search on Big Picture if interested). Anyhow, I am downloading them using Internet Download Manager running in an XP virtual machine in VMWare on my Ubuntu 10.04 PC (due to the queuing, restart and speed capabilities of IDM). But I digress - the files are being saved on the host (Samba share) without a file extension. So I have a collection of files with names like


The Douglas MacArthur Story

I wish to add the extension ".mp4" In Windows this is simply done with the command


rename *. *.mp4

This of course does not work in Linux. I have researched the Linux rename command and reviewed a lot of examples. However, I have not found a way to add an extension to a batch of files which are named with no extension to start with. The spaces in the file names also seem to present an issue. At the moment I am renaming them from the Windows VM while they are sitting on the Samba share using the ancient File Manager program from Windows NT which works great on XP. I have experimented with the file rename facility in Gnome Commander however, it does not seem to want to do something so simple.

OpenSUSE :: Size Of Share Stays The Same After Reinstall OS And Volume Extension?

Mar 30, 2010

I did hit a issue with volume extension after reinstalling the OS. SLES 11.2-

Before the reinstall I had a single fiber volume with 1 logical drive XFS. I did extend the volume with a second fiber storage and the logical drive extension without any issues. After the reinstall OS everything still worked fine. At one point I did have to extend my volume again and also the logical drive in it. The extension went fine, also the logical drive got bigger on the server side.

But the issue is that the share size for the users stayed the same. It has something to do with the xfs files on the server that are getting installed when creating an xfs file system. I can simulate this issue.

General :: Installation Utilities Split Root File System

Jan 21, 2011

standard Linux installation utilities split the root file-system and the home file-system on two separate but relatively equal-sized partitions? For example, when I put fedora on an 80GB disk, it automatically gave the root file-system 32GB and home 30GB and the swap 8GB of space. However, since my home file-system has a directory with 28GB of files in it, why is my root file-system reading 100% usage? Is the home FS overlaid on top of the root FS? Is there an advantage to doing this? I just made a boot partition (50mb or so), a root partition (90% of the disk space) and a swap (4%-5% disk space).
