Programming :: Keep Original Mod Date Of A File And 'date' It Back To Same File?

Jul 12, 2010

I would really like to preserve a file's original modified date and pass it back to the file as the same attribute after a script has worked on it. I get a lot of JPEG files from different places on the Net which I either turn around and upload or burn to disk, and having the "original" date of either download or last mod in a graphics app would be for me, in the long run, a lot more helpful when deciding, for instance, which files to "recycle" or pass on backing up more than once.I've tried doing this on my own every now and then. Where I run into problems is that it appears "stat" and "date" use different formats for date information, and I can't seem to puzzle out how to "translate" one to the other satisfactorily for the latter command.

Just to give an example:
stat foo.jpg |grep Modify gives me
Modify: 2010-07-12 06:28:56.890625000 -0400

Passing that string as-is to date foo.jpg, I get the errordate: unknown option -- 0 and the usual semi-courteous suggestion to Try 'date --help' for more information.Somehow my TexInfo database got screwed up somewhere along the line and info dategives me the short article on date input formats, not the full documentation for the command

General :: Use Date With Touch To Create New File With Date Based Name?

Mar 12, 2010

I am using CRON to create a new, blank file, every minute, in a specific location on my web server. After web searching, and reading man pages, I get the impression that the following command is supposed to work:touch /home/mydomain/var/folder/attachments/`date +%H%M`.txtThis should give me a new file with a file name that is the current hour and minute.However, when executed, the CRON mailer reports:touch /home/mydomain/var/folder/attachments/`date +/bin/sh: -c: line 0: unexpected EOF while looking for matching /bin/sh: -c: line 1: syntax error: unexpected end of fileSo, it looks like shell is seeing the plus (+) sign as an EOFObviously, nothing get created.What would be the easiest, single line command to create an empty file, at a given location, with a time based file name

General :: Delete /etc/passwd And Recover It With /etc/passwd - From Runlevel 1 The Lastly Created User Is Not Having His Account After Recovery?

Jan 14, 2011

we know that /etc/passwd - is a replica of /etc/passwd file and acts as a backup in any damage done to /etc/passwd file..i have observed a strange thing in RHEL 5.4....for example... if /etc/passwd has 100 accounts.. then /etc/passwd - is having only 99 accounts....when i add 101 useraccount with "useradd" then /etc/passwd has 101 accounts and /etc/passwd is having the 100th account of /etc/passwd - ..when i delete /etc/passwd and recover it with /etc/passwd - from runlevel 1 the lastly created user is not having his account after recovery.. what is the solution? this is same case even with /etc/shadow and /etc/shadow -

Ubuntu Multimedia :: Digikam - Renaming On Import - "Create Date" Versus "File Modification Date"

Jan 24, 2011

I just switched from a basic digital camera to a more advanced one that stores both Jpeg and Raw (.Nef - it's a Nikon) files for me.When importing files in Digikam, I rename the files so that they start with Date and Time. Example: 20110121-223748.JPG for a photo taken on Jan 21st 2011 at 22:37:48.I was a bit surprised when importing both the JPEG and the Raw version of the same photo, that the filename is different by a few seconds (no constant offset, sometimes they are the same):


I did some "research" by looking at the exif data of both files (using "exiftool 20110121-223748.JPG" from the command line). Here is what I got back

(amongst other data):20110121-223748.JPG
File Modification Date/Time : 2011:01:21 22:37:48+01:00
Modify Date : 2011:01:21 22:37:48
Date/Time Original : 2011:01:21 22:37:48


So it seems that Digikam is using the "File Modification Date/Time" (different in the Jpeg's and Raw's of my camera) rather than the "Create Date" (the same for both Jpeg and Raw). (The few seconds difference in "File Modification Date/Time" between the two versions of the same photo is probably due to the time that my camera needs to write away the data on the SD memory card. I guess.) Is there a way to have Digikam use the Create Date? (Or the Date/Time Original?)

PS: I'm on Ubuntu 10.04LTS, using DigiKam 1.2.0

I have a Debian 5.0.7 installed to my server. I try to install Apache and SVN to this server. I use this tutorial: http://www.howtoforge.com/subversion...-ubuntu-server

The rights for the passwd file:


And apache2 is running like this:


And if I try to login to my page I got an "Internal Server Error" page.

And my error is in the apache log is this:


So I'm a little bit confused about it. The apache2 should have rights to open this file. I checked it, the file is exist and the apache2 is have rights for it. I don't understand it.

Security :: Deleted File Stripes / Log Into A Passwd Less Acct?

Jul 2, 2010

I work for a seismic company that has recently experienced a security issue. Because we have an isolated network that is used for HPC work we have a very open security structue ie password less accounts rsh rlogin etc. We had, seemingly,a user that has maliciously deleted another user's files but I still haven't figured out how. So far I have been able to prove that this user has remotely logged into another host under that user's account... or at least that their workstation did. The /var/log/message file shows logins from their workstation as that user multiple times durring the times that these files were being deleted. There are wildcard searches for these files in the history in this host. There is a vi session initiated on this host for a file called delme (delete me) and then a chmod +x for this file. and then a deletion of this file (rm delme). Funny things: this user has no business in this acct. this user was bounced off the other host (permission denied) when trying to log into the other host and then as root logged into the other host as the other acct. repeatedly... ie. rsh -l xxx (permis den) then as root rsh -l xxx (logged in) why not su xxx and then rsh? password less acct?! why use root privs (which they sholuld not have) to log into a passwd less acct? Can't see any remote logins to their workstation from elsewhere. can't find smoking gun. no execution of delme script or any other rm /*/xxx/* sort of command that proves when file deletion of striped files happened?!

changing root passwd soon.need proof that no remote logins to a CentOS 5.3 workstation could be responsible.
Could mean someone gets fired.how can I be sure that no other users logged into this machine and then into another machine for sure?

Ubuntu Multimedia :: VLC Player Can't Access MKF Filed On NAS

Jun 13, 2011

I am bringing up a Ubuntu 11.04 PC to hopefully use as a U-HTPC. It is collocated on a LAN with a Windows 7 W-HTPC and two NASs that have movie files stored as MKV files. The U-HTPC is connected on its back side by HDMI to my Sony Receiver and on to my Sharp HDTV. One of the applications I have installed on the U-HTPC is VLC Player which I want to use to play the MKV files from the two NASs. But so far I cannot play any MKV file because I have no access to files on the NASs. I should say the NASs were installed to store MKV files to be viewed by the W-HTPC running VLC Player. That worked fine, but I do not have access to the MKV files from VLC Player running on the U-HTPC. how to gain access to the MKV files on the two NASs from U-HTPC.

General :: Parsing File Dates - Get The Date Of The Last Time A File Was Modified ?

Jan 11, 2010

I need to get the modified date on a file in linux to use in a script.I tried using 'ls -l' on the file, but this caused problems when the date turned from a single digit into a double. The reason for the problem was because I was parsing the result string on spaces.How can I get the date of the last time a file was modified so I can use it in a script? For example, if a file was modified on 1/11/2010, I need the 11.

Ubuntu :: Organize Folder With Images By Date Taken Rather Than Date Edited?

Aug 1, 2011

As a photographer I'm constantly taking photos and storing them in folders. Now occasionally I'm using two cameras (either for different settings or an assistant is also taking photos) which means that for one event I can have differently named images.Both cameras have the same time set (which always helps in Windows) but in Ubuntu when trying to sort my folder by date taken I can't.The options I'm given are to sort them: Manually, by Name, by Size, by Type, by Modification date and by Emblem.Now none of those are helpful to me once I've done a few edits to the images.So please if anyone knows, how do you organise a folder with images taken on different cameras by Date Taken rather than Date Edited?
