I'm trying to extract the sender id from a fairly large number of files and am having trouble assigning variables from a file. Here is what I have so far, (which is fairly kludgy I know, but it's been some years since I've done any scripting or programming, and I find that I have lost the knack to a large degree).
[Code]...
I am using the diff command with the -r option, to compare a large number of files and files in subdirectories. My main interest is to find out which files have been changed, and not what the actual changes are, and since a lot of files has been changed, it would be a lot easier to view the file names only. Is there and option for diff that might do this, or does there exist a similar tool/command that could do the job?

I've a directory containing around 2.8 lacs of files. I want to move them to another directory.If I use cp or mv then I get an error 'argument list too long'. If I write a script like
for file in ls *; do
cp {source} to {destination}
done
then because of ls command , its performance degrades.How can I do this?
I am facing problem in copying a large number of file 18 lakh (18,000,000) files from my personal hardisk to another hardisk each file is very small and size of folder is around 3.95 GB copying files using copy given by Windows is frustrating and I am not even able to compress file its giving me error that its not readable.And problem is I am not able to open this drive in Linux it showing me error there saying do diskchk in Windows and Windows disk check is also not able to repair this drive and goes into some mode unsolvable.Is there any way to open disk with error to open in Windows and if not any way I can copy data faster?ERROR: Disk labled EDU is corrupt go to windows and chkdsk /f there and reboot into window 2 times.

problem: Trying to use a vendor supplied cross compile environment. The environment runs as a chroot'd env and works just fine. I have a large number of additional modules that I wish to compile in the chroot'd environment. FYI, these modules are also (succesfully) compiled for other targets not using chroot'd env's. Copying the source files into the the chroot environment is not an option (don't have hours to wait for copies to finish and it would break the make system). Having them live in the environment is also not an option (the chroot build is a tiny part of the build process and we cannot revamp our entire source tree to accommodate it).
I am looking for a way to have the compiler in the chroot'd env have access to a path that is outside of the env and typically higher up in the same path that holds the chroot'd env. I have tried soft links (they don't work as expected). Hard links only work for single files and there are 10's of thousands of files that would need to be linked. I am not sure how I would go about exporting the additional files and then mounting the exported files in the chroot'd env (or if that would even work).
This problem is not exclusive to Ubuntu, I've experienced it in Windows and OSX as well, but it seems that almost every time I transfer a large number of files (i.e. my music collection) between my desktop computer and laptop via my external hard drive, I end up losing files for no reason. I usually don't notice the files are missing until later on, because I am never informed of any data loss. Now, every time I make a large transfer of files, I just do it two or three times to ensure that I don't lose any files.

Here are the commands I have mainly been trying with various edits:

So far the most common complaint I have gotten "missing arguments to execdir".
This is on Ubuntu 10.04
I have the standard problem of trying to count a large number of files in a directory (>100k)
I have tried: ls ~/user/images/* -l | wc -l and find ~/user/images/* -maxdepth 1 -type f | wc -l
In both cases, I get the argument list too long error message.
I have tried using xargs but I can't seem to get it to work right.
The command
returns a valid answer but it includes all the subdirectories in the file count.
I want to move files from a $SOURCEDIR to a $DESTBASE/$DESTDIR. Under $DESTBASE there are many directories, and I need to test beforehand if a file from $SOURCEDIR already exists in any of them.
This is obviously extremely slow, and the real use case involves dozens of dirs and thousands of files. Creating a temporary "index" file for the find command (instead of running it every iteration) speeds it up a little, but it's still very clumsy.
I have two servers, one has an empty / and the other has a subdirectory with a large number (4 gig) with many, many files. I need a way to transfer the files en masse from the server with the large number of files to the one that is essentially blank.I don't have space on the used host to simply gzip all the files. I've googled this and see that there may be some combination of tar and/or gzip that will let me do this with some sort of redirection.
I really need and example line of how this can be accomplished. If my explanation seems rather sparse, I can supply more details.
I've got a large .tar.gz file that I am trying to extract, I have had a look around at the problem and seems other people have had it, but I've tried their solutions and they haven't worked.The command I am using is:

I have to extract last number from filename.
ex- my file name is a10b8c1000
so i want to extract 1000 from it.
i tried using sed
sed 's/[a-z][0-9]*[a-z][0-9]*[a-z]//g' a10b8c1000
but sed looks for content inside file.
I've these path:
Code:
xxx/yyy/zzz/0908/aaa/a.txt
xxx/yyy/zzz/0909/aaa/a.txt
xxx/yyy/zzz/0910/aaa/a.txt
fff/ggg/hhh/iii/jjj/0911/aaa/a.txt
fff/ggg/hhh/kkk/0912/aaa/a.txt
and I would like to extract only the number, so that I've get the result
Code:
0908
0909
0910

How can I do it in bash?
I have a large number of log files, on a linux box, I need to cleanse sensitive data from before sending to a third party. I have used the below script on previous occasions to perform this task, and it has worked brilliantly (script was built with some help from here :-)

However, now one of our departments has sent me a CLIENT_FILE.txt with 425000+ variables! I think I may have hit some internal limit. I have tried splitting the client file into 4 with around 100000 variables in each, this still doesn't work. I'm loathe to keep splitting though as I have 20 directories with up to 190 files in each directory to run through. The more client files I make, the more passes I have to do.
I have a 50000 line(ish) set of records in a file. I have another file where I have filtered out all the line numbers for those which have an error of various types. e.g column count, field type etc. I want to get all those lines into a separate file so I can sanitise them. There are abt 3-4000 of them.
How can I access those lines which I want to isolate into a single file? I have all the usual linux stuff available and a bit of understanding of regexps.
i've got a select based application that wants to support a large number of mostly idle connections. the code is java and works on windows, suse enterprise linux, mac os x. it does not work on centos 5.5 (32-bit, 2.6.18 kernel, 1G of memory).
i've read and followed the directions in various articles about tuning linux for large numbers of connections (including the C10K problem), and gotten the number of sockets up to 3200.
these didn't make any apparent difference:
[URL]
on windows, i can get up to around 78,000.
on suse enterprise linux (a few years ago), i got up to 90,000. that's where i got bored and stopped.
on my mac laptop with os x (snow leopard), i got up to 10,500.
i have used ulimit -n 10240
my current goal is 10k sockets.
the test is that i'm opening one socket at a time until it fails. when it fails, many of the sockets which have already been opened also fail, in one giant cascade. sounds like a buffer / memory problem.
each group of 64 sockets gets a thread to manage select calls for them. thus i'm only using around 61 threads total when it fails.
I can not for the life of me determine how to get the monitor serial number / manufacture date using Extended Display Identification Data (EDID). Does anyone know? None of the following provide this info:
monitor-get-edid
monitor-edid --v
monitor-edid --MonitorsDB
monitor-get-edid | monitor-parse-edid
dmidecode -q

I'm running 64-bit 10.04, upgraded from 9.10. The problem I am experiencing is that any user accounts aside from my main account are problematic. This includes any accounts I add, as well as the GDM guest session.The specific problems that I have thus far experienced are as follows:
1. The desktop loads often improperly. In the latest instance of this the graphics on the right side top panel were randomly chopped-up, leaving parts of my clock on either side of the volume control, among other things. 2. If I make ANY customizations to the desktop at all, the desktop takes nearly a full minute to load on log-in. 3. Flash videos don't work properly on Firefox. Sometimes they only play after refreshing a page, often they will not load at all. Also, attempting to load or play a flash video will sometimes causes Gnome or Firefox to crash. 4. (And this is the one that REALLY has me stumped) Whenever I log into my main accountant after logging out of another account, the IBus control appears in my system tray.However, when I open the IBus preferences the associated check box is (and has always remained) unchecked.Not sure where to go with this one. More than anything, the IBus bug makes me unsure of where to even begin looking for the problem.
I am attempting to upgrade a system from 4.7 to 5.2 using a (now) DVD drive attached to the onboard IDE. Originally I had tried using a remote NFS image and a USB stick but I thought maybe there was a problem with the image. I can get up to the point of the installation of selecting the keyboard for the system and then it freezes and never goes any further. It doesn't appear to be a kernel panic since I can still switch between consoles.
I've got an MSI K9NGM2-FID with 14 drives in it. It serves as a file server for our backup server. It's got a secondary 4 port Silicon Image SII 3114 SATA card using the sata_sil module, and an old IDE Promise FastTrak TX2000. Technically I could have 16 drives but the 750W PS is walking the fine line on tripping it's self-breaker with the 14 drives and 7 fans. I would like to NOT have to disconnect all of this to do the upgrade.
I thought maybe that running the install using the "noprobe" option would help so it didn't detect and load the modules for the Silicon Image or the Promise cards and detect all of the drives but it still gets stuck on the step after selecting the keyboard. The installation info console and the dmesg console don't really provide any useful information. The installation console says:
INFO : moving (1) to step welcome
INFO : moving (1) to step language
INFO : moving (1) to step keyboard
INFO : moving (1) to step findrootparts
And the last lines of the dmesg console says:
<6>device-mapper: multipath: version 1.0.5 loaded
<6>device-mapper: multipath round-robin: version 1.0.0 loaded
<6>device-mapper: multipath emc: version 0.0.3 loaded
Is there a hidden "debug" option that will turn on a lot of extra logging?
I have on my windows machine several hundred files that are a format of .nc .ncs for a CNC machine. I need to convert them to txt which is something as easy as opening in notepad and then saving as .txt but there are so many that this kind of action would take way too long.
The reason I am writing the linuxquestions is because I would feel more comfortable in loading a live CD and using some sort of terminal command to do this than I would to download one of the many "freeware" type programs I have found for windows (even more so since I have had a root kit before and had to start all the way over to get rid of it).
I need to know:
1. Is this possible to do with the terminal without super advanced knowledge.
2. Can one please point me in the right direction; something to read or an example
How do I adjust the dpkg --get-selections >installed so that it tells me about a linux installation that is not active. Currently I can not load the original installed Ubuntu on the HD and am using the live CD. How do I extract the list of installed applications for the system on the hard disk
View 9 Replies View RelatedI have been having a lot of trouble lately with installing from CD/DVD. The DVD reader/writer on this laptop is new. Nevertheless, trying to install Ubuntu onto an exernal HD, I get 'input output error on sr0 logical block (a large number) After a long time the booting proceeds to a point, but I never get the actual installation started, and have to shut down manually.
The CD is fine, says the Ubuntu-checker. I just installed using my sons laptop, and there was no trouble. Question: does this indicate a motherboard failure? A memory block damaged? Do you know of a diagnostic tool I can use to check the reading of a CD/DVD?
Recently, I've run into a rather interesting but also quite annoying instance of graphical corruption: a large black rectangle covering all or part of the window various running applications. What makes it interesting is that this graphical corruption only seems to occur in applications that have at least 2 tabs open. I've confirmed that it happens in pidgin, nautilus, gnome-terminal, and gedit; the latter 3 are shown in the attached screenshot.
Clearly, it has something to do with my graphics driver. I'm currently using the open source radeon driver in ubuntu 10.04 with a Radeon 9800XT.
I just installed maverick on my son's netbook, and so far we like the new unity interface. The main issue is that there seems to be a maximum number of apps that can be listed under any particular category in the applications browser. So for instance when he goes to his "Games" category, it only lists applications up through S (he has a lot of games installed).
So far I haven't found a settings panel for unity. There has to be a way to bump up the maximum.
I've discovered that Dolphin seems to lose random files when copying many large folders.
I first noticed this a few months ago when I tried to copy my music library from one folder to another on the same HDD. It consisted of around 600 folders and 6500 files. During the copy there were no errors but after the copy I found that some of the newly copied folders were missing files. I put it down to human error or a glitch.
Yesterday I tried to copy 13 folders containing rips of some of my DVDs. Each folder basically had one film of either 700MB or 1.4GB. Again no errors showed up during the copy but I found 3 of the newly copied folders were empty.
It's not so critical with music or films but I can't afford to lose work data like this.
Has anyone experienced or seen a similar problem with Dolphin? I'm going to have to do some more extensive testing but this is not good.
The first time I noticed the problem I was running KDE4.3.4 (I think) and now the latest was with KDE4.4.0.
I want to automate this using script.How to automate it?

View 6 Replies View RelatedI am interested in setting up speech recognition on my notebook. I have installed Sphinx3 and pocket_sphinx for my distro (Fedora 14), but have googled without success looking for an entry-level guide to get me started.I am wading through the doco at CMU, but I'm finding it hard to relate their text to the installed files on my system. They assume the user has downloaded and compiled from source, whereas I just used 'yum'.
Better: is there a front-end which presents a more usable interface than the fairly sparse man pages available? The sphinx3* tools do not seem to have any man pages and pocket_sphinx has man pages that assume I know what I am doing. As far as speech recognition is concerned, I am very much a pbeu (poor blinking end user) with no training.
