Programming :: Know Which File Under The Folder Is Being Opened / Created For Writing?
Apr 23, 2010
My program need to monitor the foler to know which file under the folder is being opened/created for writing. I add the folder into watch list using inotify_add_watch, when a file -- say 'AA' -- is created, I'll get the event through read api call. But the inotify_event only have file name 'AA' and a event mask. these parameters can't help me to know how the 'AA' is created/openned. So I have to scan the /proc folder to get to know how is 'AA' created/openned. I don't think this is a efficient way, especially if there are lots of files are openned/created in a short time span.

Can someone please help me on how can i create a script that will monitor file creation on a single folder and sending the newly created file on a separate folder? Only the new created file must be transffered or copied to the other folder. The old ones remains.I urgently need this for production deployment.

There is the Archive::Zip I think I can use with Perl 5.10 but I don't know how. I don't want to read or write any files, just zip something in memory, with best compression, like
$text = "this is a test";
$zippedtext = &Zip($text);
sub Zip {
[code]...
I guess it's only a few lines.

i am working on this thread: [URL] if it is better to open a file every time i need to write to it or should i keep a file open the whole time and when i am done with the script, close it and sendmail it out?
Or i just thought of this: i could keep concatenating to a string and just sendmail when done.

I have this nasty habit of refreshing desktop in a quick succession by right-clicking and selecting 'Refresh',on my XP system at office.(And,iam sure most of us do the same).With Ubuntu,if a right-click on desktop slowly and select 'align by...',it simulates the XP refresh action as explained above.But,if i perform the same action rapidly,it takes this first option from right-click context menu,which is 'Create Folder',and results in an empty folder being created on desktop.I tried double right-clicking and again it created an empty folder.Is there any workaround to handle this.I mean:Can the right-click context menu items be shuffled so that the 'Create Folder' option is moved from 1st place

I'm a little bit confused with partitioning the filesystem in Linux. the difference between creating the file system with fdisk and mkfs (when formatting the disk). I can't clearly tell my problem, so please look at this picture:

Using C++, I want to process sub-folders on my home folder sequentially each with a special naming format and containing some binary files in it:
Code:
1/
2/
3/
4/
5/
6/
...
Give above folders, I will process files in 1/ at first, 2/ at second, 3/ at third, and so on.
For some n/ folder, if I realize that n/ actually does not exist in local file system, I do not want to wait for it. Hence I will keep processing (n+1)/ folder, and so on.
However, when processing some (n+m)/ folder, previously not processed n/ folder may have been created on local file system. In this case, I do not want to miss processing it, but somehow detect its creation and process it. After processing n/ folder, I want to continue from (n+m+1)/.

I'm new to UNIX scripting; I�m stuck with the following I have an Oracle SQL script that takes three parameters
1- File Name
2- File Path
3- File creation date
Under UNIX I have a folder where files will be placed frequently and I need to upload those files to Oracle, what I need is a UNIX script that can do the following
Loop through Directory "/home/applmgr/snktmp"
Picks only files
Pass the file name to parameter &1
[code]....
Is the above possible? I already knows how to call the Oracle Script from UNIX Im only stuck on writing the UNIX part where it List the files attribute(name,path,date) and store them to parameters ,Looping until the last file in the directory If the above is not possible,then how can I create the below from the command line
Filename{concatenation Mark}filePath{concatenation Mark}creationdate
Filename{concatenation Mark}filePath{concatenation Mark}creationdate
Filename{concatenation Mark}filePath{concatenation Mark}creationdate
Filename{concatenation Mark}filePath{concatenation Mark}creationdate

I been using linux for a while, but I havent had the time to really learn it. Something Id like to get more familiar with is bash so here is a simple example of something I would like to do:
I have a directory full of files. For each file in the directory create a new subdirectory with each files name.
I tried this:
#im already in this directory
aaa=./*
for a in $aaa
do mkdir $a
done
One of the problems is that there are spaces () and - in the filenames so I get many subfolders with names like "-" which i don't want.
I tried stuff like:
aaa=./*
for a in $aaa
do mkdir "'"$a"'"
done
This of course also did not work.
Additional I tried just creating a folder with the name of one of the files and I got this:
mkdir: cannot create directory `(audio) - R56339.EXE': File exists
Well yeah a file exsists with that name, but I want to create a folder- why is there a conflict?
Just to be clear here are the contents of this folder:
~/Desktop/LAB/Media/Drivers - (Image Deployment)/Optiplex_GX260/XP> ls
(audio) - R56339.EXE (NIC-Onboard-Intel) - R54402.EXE
(Modem-datafax-V92) - R54403.EXE OEM_Applications
[Code].....

I was wondering if there is a way to make Nautilus scroll up when opening folders. If I open a folder at the bottom of the page, the subfolders open below and I have to use the scroll bar to move down the page to see what's under the top folder. I would like to have it put the opened folder at the top of the page so I can see as many subfolders and files as possible without having to scroll. Something like the file roller when you are looking for a place to extract files. It does exactly what I'm looking for. Are there any settings I can change in Nautilus that would provide this function?

I was created one folder in linux with current time was 1978(For example). I was moved this folder to usb(FAT32 file format).While seeing this folder in window its not showing the folder time created time stamp, because the USB file system only support the year after 1980 . But again i am putting the same folder in linux ,its showing the correct time stamp.How is it possible? Because FAT32 only supports timestamp after 1980, but still its showing 1978 in linux system

Initially I thought - use a for loop with ls in it:
Code:
However this causes lots of problems (folders have extensions, I have duplicate folders, the names with spaces create a folder for each element of the name).
The contents of the folder is basically movies (some with subtitles). Some of the names have things like (original) or CD1 CD2 in them.

There's a folder on my Linux desktop which shouldn't exist. The first time I saw it, I thought I'd accidentally copied it from somewhere else, so I deleted it. Now it's back again. So it must have been automatically created by some process, but what can I do to figure out which program is creating it? I think it's likely that if I delete the folder it'll eventually be created again, so I should be able to catch this program in the act if anyone can suggest a technique for doing so. By the way, there are no files in this mystery folder, and its name is the same as another folder I created months ago to hold my personal documents, not something that a program would create to hold its own configuration files or the like.

I changed some settings to see what will happen ( specifically to login with having to type my password) and now I can log in without a password. The problem is that I think that my password is still required, but now I can't use my laptop. Here is what happens log in (it doesn't ask for a password), then I get the error that it can't update ICEauthority, then I get the error "There is a problem with the configuration server./usr/lib/libconf2-4/gconf-sanity-check-2 exited with status 256)I also get the error that Nautilus can't create my Desktop folder and .nautilus folder.The problem is that I do not have another account, as in no root account. Each time I had to do administrative tasks ,like install software, etc, i used the cli with sudo and the command. If I wanted to do a few commands, I usually entered sudo -i

I'm dipping my toes into some bash scripting and was wondering if there was a way to delete a file not based on how old it is, but rather how many other files are currently in the folder... or something to that effect....
What I'm doing is creating a script to back up a folder nightly. I'd like to keep a maximum of 3 backups. However in case the script for some reason fails to run one night (computer turned off possibly) I don't want to set the condition for deletion to be the date.
I know that if I run:
Code:
find /path/to/files* -mtime +3 -exec rm {} ;
that it will delete everything older than three days. -atime and -ctime don't seem to be what I"m looking for... is there another command I can use to achieve what I"m trying to?
