I am having one particular folder (/home/sam/officedocuments) which is having hundreds of folders and files. I think I deleted some files and folders by mistake but I'm not sure.

How to find which files / folders were:

  • deleted recently in Linux?
  • changed recently in Linux?

I just want to know which files and folders were deleted. Recovering those deleted files and folders is not important for me.

OS: CentOS

You should tell us what filesystem you are using. For example with ext2, ext3 and ext4 You could probably use ext3grep utility to find out information about deleted files. With some scripting it should be possible to put together simple application that lists deleted files based on specific directory. These utilities however needs raw access to disk and as such are extremely dangerous if not used properly (non-blocking read only operations should be completely safe if you remember that writing to disk same time could cause current operation to return broken/incorrect data). –  Sampo Sarrala Jan 8 '13 at 21:59

…changed recently in Linux?

Use find to search by modification time. For example, to find files touched in the last 3 days:

find /home/sam/officedocuments -mtime -3

For "older than 3 days", use +3.

…deleted recently in Linux?

Pretty much impossible. When a file is deleted, it's simply gone. On most systems, this is not logged anywhere.

Thanks. For 3 days, I need to use 3...what I need to use for last 30 minutes? –  iSumitG Jan 8 '13 at 21:00
    
Does Linux always asks for confirmation before deleting any file / folder? –  iSumitG Jan 8 '13 at 21:06

"Pretty much impossible" This is just plain wrong and because of this I have to downvote this. Deletion times are stored in some filesystems, example of such fs is ext3 filesystem. ext3grep might help when hunting down. I got superuser.com/a/433785/132604 that has some information and links to utilities that could be used to find (possibly recover too) deleted files and information about them. When you delete file, in most filesystems, it is not actually removed but marked as space that could be overwritten in demand. –  Sampo Sarrala Jan 8 '13 at 21:43
    
You might be able to restore files from a backup and compare a list of those files with the ones on the filesystem. That would yield a list of missing and newly created files. Grawity's answer already show you can filter on time, thus you can limit that to only the deleted files. –  Hennes Jan 8 '13 at 21:47

You should probably install Inotify Tools. then you can use the inotifywait command to listen for events happening for the specified directory.

Specifically if you want to watch for deleted files and folder use this

inotifywait -m -r -e delete dir_name

and log this output in some file.

Hope this solves your problem

Sound like best approach for this. There's promising cli-app/daemon named iwatch that you might want to include in your answer. +1 for using right tools to solve problem. –  Sampo Sarrala Jan 10 '13 at 9:29

Linux does not generally ask for confirmation before removing files, assuming you're using rm from the command line.

To find files modified in the last 30 minutes, use touch --date="HH:MM" /tmp/reference to create a file called reference with a timestamp from 30 minutes ago (where HH:MM corresponds to 30 minutes ago). Then use find /home/sam/officedocuments -newer /tmp/reference to find files newer than the reference.

If you deleted files using a GUI tool, they may still be in some kind of "trash can". It depends on what you're using for a desktop environment. If you used rm from the command line, then try one of the utilities mentioned in this answer. (Hat tip to @Sampo for that link.)

Just don't say "gone forever"... see comments on another answer. Now I feel like this: xkcd.com/386 :) –  Sampo Sarrala Jan 8 '13 at 21:47
    
@Sampo: Thanks, see my edit. –  bstpierre Jan 9 '13 at 15:24
