I had accidentally deleted a few files from an Ubuntu Desktop.
Now I need to recover only the perl files which had been sitting in /home/user directory.
How can this be done?
I am able to boot using a live Ubuntu USB.
Please explain.

Before you start:

• It's always a good idea to work from a copy of your deleted data, so copy your entire disk before you begin


• If you cannot, boot from a Live-USB/DVD before you begin.


• If you cannot, know that by each and every single byte you write to your disk right now, one byte of one of your deleted files will be overwritten! (i.e. by installing PhotoRec and TestDisk, some deleted files will be overwritten by the applications that you're going to install if you continue!).

What are the main differences between TestDisk and PhotoRec?

TestDisk is a lot more efficient than PhotoRec. The problem with TestDisk is that it doesn't always recover all deleted files. If you accidentally reformat a partition, TestDisk can recover thousands of files without missing a single file, but if you deleted a file by sending it to the Trash and then emptying the Trash, TestDisk can't always recover it.

So use TestDisk first, and if you recovered all of the deleted files with TestDisk, then you're done. If you recovered most of the deleted files with TestDisk, you can decide whether you're done or not. If you're not done after running TestDisk, you can try recovering the deleted files using PhotoRec.

PhotoRec can selectively recover files based on their filetype(s), but PhotoRec / TestDisk can't selectively scan an individual directory for lost files unless you had mounted a whole hard drive partition as this directory. In some cases, the filename is stored in the file itself. PhotoRec tries to recover the filename in this case, but most of the time PhotoRec can't recover the filenames.

Recover files based on filetype using PhotoRec

1. 
   

   Install TestDisk from the Ubuntu Software Center.

   
   
   

   sudo apt-get install testdisk
   

   
   


2. 
   

   Launch PhotoRec.

   
   
   

   Open a terminal and launch photorec (as root).

   
   
   

   sudo photorec
   

   
   



3. Select hard disk.



4. 
   

   Select partition type.

   
   
   

   If your hard disk has Linux partitions, then select [Intel].

   
   


5. 
   

   Select filetype option.

   
   
   

   Move to [File Opt] and press Enter. Here you can disable all file types by pressing s. Use space to toggle the check button. Select filetype(s) to recover. For Perl you can select pl for Perl script or pm for Perl module.

   
   


6. 
   

   Select options.

   
   
   

   Photorec also has a list of different options. Under normal circumstances you don’t need to modify them.

   
   


7. 
   

   Select partition.

   
   
   

   Move the selector up or down to the partition from which you have removed the file(s). Then select [Search] and press Enter.

   
   


8. 
   

   Select filesystem type.

   
   
   

   If you are using Linux, it's going to be ext2/ext3/ext4, so the default selection is ext2/ext3. Otherwise if you are recovering files from a partition formatted as FAT or NTFS select Other.

   
   


9. 
   

   Select space for analysis.

   
   
   

   Select Free if you didn’t write to that partition after removing the particular file, otherwise select Whole.

   
   


10. 
    

    Select a directory for the recovered files

    
    
    

    Select the path where the recovered files will be stored. Then press Y.

    
    

Photorec will show how many files it has recovered.

"Ubuntu 14.04+Dummy Output+PhotoRec"

Hi everybody,
Can any of you help me, please?
A number of things happened with my Ubuntu 14.04 system.
Here the events go.
E#1: My Ubuntu system got a regular Update and then Dummy Output was shown under Sound Settings & as a consequence Input/Output voice was no more available. This means something went wrong with the Sound Card or it was Not Appearing for some reason. Then Backup Stopped working and System Settings got lost, almost all of it.

E#2: Then some Dummy Suggested that Rebooting is the Cure. Why am I calling the Tech person dummy? The reason is that he merely stated the so called Cure Name & not the Outcome which took place afterwards. Well, in this world Mostly People are not Techs & therefore in their naive selves they harm their computer systems.
This happened to me too. I Lost All of My Photos, Docs, Videos & Music!

E#3: Then a friend of mine suggested me to use PhotoRec to Recover the files, but he forgot to tell me that I need a Separate Drive to Recover those Files or there is a chance of the existing Internal Hard Drive to be Overwritten!
I did as directed and was very happy with PhotoRec until the next morning. The next day I opened my computer system and everything just Hung/Froze After Login. Until now it is in the same state. Guest Session is of no use & so is Recovery Mode & Rebooting in Grub. It'll surely bring me to the ground Zero.

The only Possibility I am seeing is to Start over with
Rebooting->Installing PhotoRec->Run PhotoRec (with an external Hard Drive this time)->Sesrch Through All the Files->Wreck a Tech Person's brain over what to do with the Unwanted and Some Software Files.
And may be...
If I'll get lucky enough. I'll get what I am searching for.
Any sensible & comprehending solution for humans, is my desire.
Thanks for reading & coming up with an applicable fool-proof sugge0stion.
