General :: Checking Changes Made Before/after Installing Application?
Aug 5, 2010
I need to know which files were added/modified/moved/deleted after compiling and installing an application from source code, ie. the command-line, Linux equivalent to the venerale InCtrl5.
Is there a utility that does this, or a set of commands that I could run and would show me the changes?
The following is sort of OK, although it includes the lines where changes occured
(eg. "@@ -2,6 +2,7 @@"), and "." and ".." that I don't need: Code: # ls -aR /tmp > b4.txt
# touch /tmp/test.txt
# ls -aR /tmp > after.txt
# diff -u b4.txt after.txt

I would like to capture the sound of my peacocks. These birds "crow" (for lack of a better word) only a few times in a day.
Usually they do so at around the time it gets light, about 6:00-ish. They might call again once before I leave for work.
The problem is to capture a high quality audio clip of their sound I need to have the recording running when they call. Turning the recorded on an hour before they call may be an option, but the size of the data file produced is rather obnoxious.
So I need something like a kind of time-lapse function for sound. I'd like to set the recording to run and then have it fill a 10-minute circular buffer.
Then when the birds call, I can go and stop the recording and then I can extract the portions from the file that I like.
Now, finally, for the question: Is there a ready-made linux application I can use for this?
I don't do a lot of audio work, and don't expect to use the program more than a few times, so I am willing to build something from source too, so long as it is easy to clean up afterwards and as long as it compiles without too many issues.
I am running Ubuntu 10.10.

My pc is custom made with the following config:
MOBO: Asus p7p55d-e pro BIOS 1502
GPU: Asus GTS 450 1 Gig
CPU: i7 860
8GB RAM
2 1TB HD, one dedicated to Windows 7 64bit Ultimate
Connected to my LG 42" LCD TV
I asked my friend who is a contributor to ubuntu, and runs a cyber security company to install it on my computer and he said that he will charge me $375 to do this. And then he said that it is not such a difficult thing, however, it will need a lot of tinkering with ubuntu before it works flawlessly. I didn't know what he meant and didn't want to get into it with him. I was wondering if you could direct me to the threads that discuss installation of Ubuntu alongside Windows 7 already installed and on a separate hardware. I don't wanna pay him that money and I'm very new to this. Also, I hope someone could explain what kind of tinkering is done before it works flawlessly.

Here are the specs on my computer:
Everything is brand new, TOTALLY from scratch build.
Mainboard is a MSI NF980-G65
AMD Phenom II 6 core processor
8GB DDR 3 Ram

Sometimes at startup I get this message "Checking disk 1 of 1". Does that mean it's checking all partitions on the hd? After a bad shutdown there is no prompt for fsck to run and the system just boots up. In fstab I have both options set to "1" for the partition Ubuntu is on, all others set to "0". Any ideas on both?

I'm having trouble installing visual python, I've downloaded the source package from [URL] as I couldn't find it on yast. On calling ./configure most tests are passed but I get an error which says I need gtkglextmm 1.2 checking in Yast I see this is already installed. Looking in the install.txt it talks about this error and suggests renaming some files, I'm not keen to do this for fear of breaking something else but as it turns out they are already named what they need to be anyway.? Now I'm truly stumped.

So, I have this application called Impact, it is an explicit time integration Finite Elements code written in Java...
[url]
I untar the pack, and launch the application calling a script, from within the untarred folder,
Code:
This launches a gui which allows me to setup a case, which needs some setup file, tipically some *.in and a mesh file, tipically some *.msh.
Other mode of executuion consists of calling the setup file as argument to Impact.sh script ( CLI execution mode, for g33k5 )
My problem is : I have packed the whole stuff into a Slackware .tgz, that places it in /usr/local/Impact, and placed a calling script in /usr/local/bin,
Code:
Code:
I decided to hack the ImpactGUI_OGL_linux_amd64.sh script from
Code:
Code:
no avail,
Code:
even after adding /usr/local/Impact/bin to PATH... won't go...
I can run this thing from within its directory... but I do not like messing within the directories of my applications, this is why I sent this to /usr/local, and placed a calling script in /usr/local/bin...

After logging onto a linux machine via SSH, I would like to be able to retrieve the name of the computer from which the connection was made. Ideally I am looking for some command like hostname or uname but that would retrieve the name of the client instead of the host.
This information must be accessible somewhere, since when I log on I get a message that contains the clinent name from the last login:
Last login: Thu Mar 11 18:42:01 2010 from my.address.com
The reason for wanting to do this is to be able to take different action in my .login file depending on which computer I am currently connecting from.

Kernel 2.6.21.5, Slackware 12.0. I have a file named juan34. I was sure it was a plain text file so, instead of running first 'file juan34' I directly did 'cat juan34'. The result was everything echoed to the console are the ascii caracters greater than 127 decimal. In other words, the screen is unreadable.
I typed 'exit' but this did not remedy the situation. The login prompt was written with these strange chars. In another console I'm running a program which I estimate will terminate execution in 20 hours or more, so I do not want to reboot the machine.
When I worked in MS-DOS, I had (made) a program that reinitialized the 6845 CRT controller, fixing this problem (for this could also happen under that O.S.). But, if there is a solution for MS-DOS, all the more so there must be one under unix/linux.

I have an HP laptop with both Ubuntu 8.04 and Windows Vista installed on it.
The other day I noticed I was running out of space in the main linux partition (the / partition, not the /home partition), so I decided to move some space from the Windows partition and move it to the linux one. I used a GParted Live CD to do that.
My partitions are ordered as follows:
Windows Vista partition (NTFS)
Main linux partition / (ext3)
Linux home partition /hom (ext3)
HP RECOVERY (NTFS - I don't know what it is, it just comes with HP laptops that have Vista on them)
So I shrank partition 1, and then "moved" partition 2 to enlarge it (GParted said everything was alright).
After doing that, I went to my linux and everything seemed to be fine, I'm also quite sure I had access to my Windows partition as always. But today I tried to start my Windows and it just got stuck on the "loading" stage (that screen that says "Microsoft Corporation" and has a green loading bar). So I shut the computer down manually (by holding the power button for a few seconds). After doing that a couple of time, I went to my linux, which worked just fine, but I was not able to go to the Windows partition. You can see how GParted looks now for my computer:[url]
As you can see, the first partition (/dev/sda1), which is supposed to be the Windows partition, is not mounted and the system doesn't seem to be able to read it properly. Here is my attempt to mount it manually:
Code:
Mount is denied because NTFS is marked to be in use. Choose one action:
Choice 1: If you have Windows then disconnect the external devices by clicking on the 'Safely Remove Hardware' icon in the Windows taskbar then shutdown Windows cleanly.
Choice 2: If you don't have Windows then you can use the 'force' option for your own responsibility. For example type on the command line: mount -t ntfs-3g /dev/sda1 /windows/ -o force
Or add the option to the relevant row in the /etc/fstab file: /dev/sda1 /windows/ ntfs-3g force 0 0

On a certain computer, I had four primary partitions. The person who installed the Windows 7 on the computer made two partitions for the Windows (sda1 and sda2). Then I made another two primary partitions (sda3 and sda4). sda3 was empty. sda4 is an extended partition that contained the /swap, and /.According to someone else, some viruses get in on the Windows partitions and can then get over to the Linux partitions if they are primary and right after the Windows partitions, or something like that. This person suggested that I create sda3 when I install Linux(SLES 10), but to install Linux on sda4. Then later I can change sda3 to secondary.So I tried this, and the Linux installation went fine.
I decided to change sda3 before I load the application software onto the computer.So I put the GParted CD in, but to my surprise I realised that the harddisk was actually 1 TB, and not 500 GB as I thought. So I had extra space to the right of sda4. I wasn't quite sure what to do with sda3. I thought that perhaps it would be better to unallocate sda3, move the current sda4 to the left, and then make another primary partition on the right of sda4, or just stretch sda4 both ways.Anycase, I unallocated sda3, and just left sda4 as it was.Hm, perhaps you can anticipate the end of the story. I removed the GParted CD, and restarted the computer, but now the computer doesn't let me choose whether I want to boot into Linux or Windows. Um, it doesn't boot at all from the harddisk.
I know it's dangerous to play with partitions, but sometimes the job won't be done if you are too afraid of doing anything, and I dare say you won't learn anything either. There was nothing on sda3, so I didn't think it would have nasty after effects. There isn't any important data on this computer yet, it was two new installations of Windows and Linux. So I guess I could format the harddisk and just reinstall everything, but I would like to learn what goes on underneath the surface.
