General :: Adding A Files Creation Date To It's File Name?
Sep 17, 2010
I have some basic experiencing creating simple scripts/making directories/changing permissions/etc. but I'm stumped on this one.
I have two linux boxes. I have a script set up on box 'A' to SCP into box 'B', grab a copy of a database backup and store it on box 'A'. It looks like this:
scp root@X.X.X.X:/blah/blah/blah/dump.23.gz /home/blah/DB_Backups/
I have generated a public key on box 'A' and placed it into the authorized_keys file on box 'B', so a password is not required and the file copies over successfully when the script is run. On to my problem...
I need to know what date the 'dump.23.gz' file was originally created when I'm viewing it after it's been copied to box 'A'. If I ls -l on box 'A' it only shows me the date it was created on box 'A' when it was copied.
What would I need to add to my script to append the backup's original creation date on box 'B' to the filename so that when it gets copied to box 'A' I know when the backup was created on box 'B'. I'm sure this is probably confusing. I've done lots of searching and can only find information on how to append the current date and time to a file name. I need to append it's original creation timestamp to the filename when it copies over.

I have a folder with hundreds of .txt files (logs of some java application) that I have to merge in to one single .txt file. This application produces a new log file everyday:
day1: logFriday10September2010.txt
day2: logSaturday11September2010.txt
...
day8: logFriday17September2010.txt
...
and so on...
I could merge the files easily with "cat" and ">>" however, the problem is that I have to do it by taking into account the date (creation or modification) of the file.
If I simple use the cat command the output file will receive for example, all Fridays in a row, then all Saturdays, etc. and in that way I'm not considering the date.
I've searched for the options of the find command, since the files after creation are not modified...I try to use this for example:
$ find . -newer <some old file>
but that lists me all files after that <old file> and not by correct date.

I have a list of .jpg files from two cellphones that I would like to rename to the file creation date... but so far I can't seem to find a suitable script (or anything remotely close to what I need).
These are jpg's snapped on cellphone cameras, so no EXIF data exists.

I'm looking for a terminal command that gives me the latest created folder in a directory tree.
Code:
ls -lR --sort=time --reverse
this i almost good, but a) it gives me files (rather than folders only), b) it sorts the files by folder (rather than just giving me a plain list of everything) and c) it takes way to long.
what i want:
Code:
2010-08-01 ./path/to/folder/a
2010-08-03 ./path/to/folder/b
2010-08-06 ./another/folder/c
[code]....

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

I am trying to rename multiple files in a directory and add the Date/Time stamp to the file name.
Example:
file1.txt
file2.txt
file3.txt
Renamed to
2009_02_01_21.txt
2009_02_02_21.txt
2009_02_03_21.txt
I am able to accomplish this using this command:
mv file1.txt "`date +%Y_%m%d_%H`".txt
But I want to automate this task, I have many files to process and I dont want to do them one by one.
I already tried this but it does not work
mv *.txt "`date +%Y_%m%d_%H`".txt

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

I am using Ubuntu 9.10 and have been using digikam to get my photos and videos in order. A lot of the creation dates are messed up, but I have been using the "adjust time and date" tool in Digikam to ge the photos set to their correct creation date.
However, when I try to do that on a .mpg or .avi I get an error that reads "Unable to adjust metadata in ****.mpg" I've tried opening the videos in other programs, like avidemux and cinelerra, I even tried opening the properties section of the videos. I haven't been able to find a way to modify the creation date of videos.
Is there a way to change the creation date of videos on Ubuntu? I would prefer to use digikam, but at this point I'm open to anything. Do I need to download a plugin? A program? Use a command line command?

i'm trying to make a script that gives one output if a directory in /home is older than one month, and another if the directory is less than one month old. I looked around and saw that the creation date for directories isn't stored, or at least i couldn't find it? How is this possible to do then?

I'm trying to setup a Samba share for our work. I have it almost complete, however I can't successfully share editable files between users. The issue I'm having is that say User1 create a file test.txt, because of the 755 permissions, then User2, who has "writable" rights as per the smb.conf file, cannot edit that test.txt file.
Whevener I create a file with a user, its locked by that user. Is there a way I can set it that every folder/file a user creates is 777 ? I firgured that there's still security because of the "Valid users = " field in the smb.conf file.

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

I keep creating practice perl scripts in a linux directory using vi <filename> and need to chmod 751 <filename> before I can run it as I wish to. I'm sure there is a simple way to default my permissions or config them at creation, but I'm not familiar with it ayuda me por favor.

I was wondering if there is a command to show a real-time creation of files. I basically executed a command that will created thousands of files and takes a long time. I want to check if it is still creating additional files or if ti got frozen.

I'm just starting out with shell-scripting, but having a problem with making new text files with the touch or cat > commands.
What I've been doing is touch testfile1.txt
Also, I've tried cat > testfile1.txt (text)
Console reports "bash: text1.txt: No such file or directory. Consfusingly, it works fine in the home-directory. But if I move the file to where I want it, I can no longer view, edit, etc. it.

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.

In Ubuntu 10.10 one was able to add widgets, such as the full date (not just the time) to the top bar in Gnome. Can you do this in Unity? I like being able to quickly look at the bar and see the date (I'm forgetful) but all that is there is the time. I do miss not having the applications bar where you can look and see just what applications are running and quickly cycle between them. Right now I need to mouse over the dock (and sometimes do a little mouse dance) to open it and then scroll down it to access something that is open and happens to be at the bottom of the list. I felt that having the bar exposed was more efficient, although maybe not as elegant looking.

Is there any way to untar and only extract those files that are above a certain date including directory structure??
I restored a backup on a play server but it was a few days old. However I have a tar archive of the entire structure that is more up to date and healthy so now I want to extract all files (including directory structure) based on a date filter on the files if possible?

I am running ubundu 10.10 and want to copy all files revised after a certain date (01.02.2011) to a certain location (usb memory stick) for backup purposes. How do I use the "cp" command, or do I have to use any other command ? Or may be this is not possible in Linux ?

ls -l /tmp/empty_file*
-rw-r--r-- 1 root root 0 2010-05-30 08:00 /tmp/empty_file
-rw-r--r-- 1 root root 0 2010-05-30 12:00 /tmp/empty_file1
This looks good, the files expected to be seen are output: find /usr ( -newer /tmp/empty_file -a ! -newer /tmp/empty_file1 ) -print
But this shows me files that should not be output and likewise when I replace ls with tar it is tarring a whole bunch of stuff I do not want: find /usr ( -newer /tmp/empty_file -a ! -newer /tmp/empty_file1 ) -exec ls -l {} ;
In the end I would like to replace the "ls" with "tar cvvfp some.tar {} ;", but can't figure out what is going wrong here.
