Getting the "Created" timestamp of a PDF file in the CLI

view full story
linux-howto

http://askubuntu.com – I'd like to know if there's a CLI command to get the "Created" timestamp from the "Document" tab (from file properties of a PDF) in the CLI? I know that I can use stat to get Access/Modified/Changed info from the filesystem, but with the meta-data in the "Document" tab being embedded in the file itself, I'm not sure how to go about extracting it via the CLI. The reason I need to do this is to create a list of filenames along with "Created" timestamps for about 22,000 PDF files. Obviously, this is something far better suited to the CLI than the GUI. (HowTos)

I need to find the latest created file in a FTP folder.

Hi,

Is it possible to amend a file without changing the last modified date?

If it is, how do you do it?

If it's not, is there a way to create an empty file with the same timestamp as another file?

I know you can use touch -t yyyymmddhhmm.ss filename but, I would want the file to have the exact same timestamp as another file.

Any help would be greatly appreciated.

Thanks

****EDIT****

I am debugging a android framework. I pull out dropbox logs from device and it's created in /data/system/dropbox. Log file name is printed like this format.

event_data@1362451303699

1362451303699 is timestamp and i want to change it like 05/03/2013 16:00 for legibility.

How can i convert this timestamp? Is there any code needs to be changed?

Any help will be much appreciated.

2) How does file editor capable of editing various file formats ? Whats the logic behind it ?

UST Time vs. Local Time 3 years 23 weeks ago

Since I started using Linux in 2000, I've been running all my systems with the BIOS clock set to UST time and just let the OS handle the time zone difference. I remember reading that it was the recommended way to have it set, although I also remembering not understanding why. It's just the way I've done it for years and years.

I create a new Word document in 'Office Open XML' format (docx). I then encrypt it using EFS and add several other users to access the file.

Now I open the document and edit it, after saving it, the file is still encrypted but the additional users are gone!

i need help create a bash script that will copy files from different directory to different folders.

Hi,

I was hoping someone could suggest an alternative to code I currently have as mine takes up far too much processor time and it to slow.

The situation: I have a programme that runs on some files just before they are zipped up and archived, the program appends a one line summary of the file contents to a file called summary.log in the following format:

<filename1><file timestamp>&
