I'm struck with the following problem.
I have a data file with following data code...
(I have bigger data that needs to check all the above conditions)
get a code for the above problem
(either a shell code or a c-program)
For Linux command sort, how do I force sort to load all input into memory and sort assuming I have enough memory? Or is it best to use a RAMDISK to store the input before feeding it to sort?

I want to sort them in ascending order.
Does anybody know how to do it in Ubuntu 10.4.
I am having a file filled of blocks like (each is seperated with the <event> )
<event>
8 1 0.1118800E-04 0.1709000E+03 0.7546772E-02 0.1182204E+00

how can I copy this block if for example find "13" in the first column and "-1" in the last ? Then, looping to the rest of the file doing the same all over again?
I have a few FTP users on my linux server(running vsftpd). They all have their own directory and can upload and delete files in that folder.Now, I was wondering whether it would be possible to create special permissions/rights for users. For example, I would like to make it so that certain users could not upload .exe files, or I want a certain user to only be able to upload image files (gif, jpg).
View 2 Replies View RelatedI have several files with many lines something like this:
I'm trying to write a script that will count the number of characters per line that doesn't contain a ">" symbol and give me an average of those values. I have most of the script together but I can't figure out how to connect some of the steps.
Code:
I have very little linux experience. And need some help with a bash script. I need to a script I can set cron to run to sort files out of a holding folder into final folders. It doesn't necessarily have to be bash, but I think it would be sufficient for this. File names are formatted as such when created: Dest-Date-Time-CID-Destination# I want the files to be moved from a all in one holding folder to a folder structure like this.
.../storage/year/month/day/Destination#/VarX(type)/hour/CID/'File'
I would need an if/else if/else statement to say if Dest = A set VarX = B If for example the file name was
infinity-20100927-17:00-1112223333-4445556666.wav
I would like the above file to end up moved from
.../holding
to
.../storage/2010/09/27/4445556666/Inbound/17/1112223333/infinity-20100927-17:00-1112223333-4445556666.wav
So the script will need to make directories based on information in the file name which is delimited by single dashes. Then move files from the holding folder to the newly created "sorted" folders.
I'm here of course because I would like to know what would be the SSH command to issue if I need to delete certain files that meet certain criteria. For instance, in this case, I simply have files that almost bear the same name but still have some very minor differences.
Let me give you an example:
L0619000.log
L0619001.log
L0619002.log
L0619003.log
L0619004.log
Those in bold are those I'd like to have removed, while the "L0619004.log" is obviously to be left intact.
A few months ago I have setup a server with three hard disks. The partition mapping the disks as follows:
Disk /dev/sda: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x7ca36fee

Now I have the following problem the LVM file system don't mount properly.If I open the mount point I see only a few files of the LVM disk. If I want to unmount the disk I get the following error:
umount /data/
umount: /data/: not mounted
If I want to mount the volume I get the following error:
mount -a
mount: /dev/mapper/gegevens-Data already mounted or /data busy
The most recent flavour of Linux I've been using has been Sidux, but the update cycle in sid is a little too fast for my liking.
What I'm looking for:
- Debian Based
- KDE 4.X
- Ideally it would still be able to use debian archives (ie like sidux)
- Updates less often than sid, so you aren't a long way behind if you miss a week, but often enough to still have up to date versions of software.
What options should I use when I'm using the sort command to sort the top 5 CPU processes (ps -eo user,pid,ppid,%cpu,%mem,fname | sort ??? | head -5) showing max to min usage?
View 2 Replies View RelatedWe switched from unix to linux and we have an old report that extracted data from a database, output to an ascii file and then sorted the results in the file based on different arguments. The report now blows up when it runs,and I can only guess it is because the options for sort on linux differ slightly from unix.For example, here is one of the commands issued from within the report app that ran on the old unix box:
if sort-sequence = "descending" then
'sort -t~" -f +3.0f -4.0 +5.0r -6.0 -f '
else
'sort -t~" +3.0f -4.0 +1.0f -2.0 -f'
I will eventually rewrite the report to store the data in a local table, but I can simply adjust the options to suit the requirments of linux. Basically, I need to know if this can be a quick fix for the short term.
Currently we have migrated data from Unix linux. The data in Unix is in Big endian byte structure. Where are as Linux (suse linux) byte structure us little endian. This byte order mismatch is creating problem when data is read again in microfocus cobol.
Is there any way to set byte order in Linux is big endian?
Is there any utility to convert data in big endian byte structure to little endian byte order.
The GNU sort text utility features a non-standard -R option to randomize input lines (presumably by sorting on a hash).
OSX sort does not have this extension. Is there similar functionality available in another text filter?

I've been using Linux Mint happily for a while until a couple of days ago it just died. Froze up, nothing I could do would free it up other than a hard reset. So, I tried to install it again from a Live CD, but my laptop won't even boot into Live mode. It just sits there, saying 'Loading....'. which it frankly isn't. I suspect a major hardware fault has occurred, but have no idea what. Any ideas?
