command line - How to recover deleted files in ubuntu using live usb? [based on filetype] - Ask Ubuntu

i had accidentally deleted few files ubuntu desktop. need recover perl files had been sitting in /home/user directory. how can done? able boot using live ubuntu usb. please explain.

testdisk lot more efficient photorec. problem testdisk doesn't recover deleted files. if accidentally reformat partition, testdisk can recover thousands of files without missing single file, if deleted file sending trash , emptying trash, testdisk can't recover it.

so use testdisk first, , if recovered of deleted files testdisk, you're done. if recovered of deleted files testdisk, can decide whether you're done or not. if you're not done after running testdisk, can try recovering deleted files using photorec.

photorec can selectively recover files based on filetype(s), photorec/testdisk can't selectively scan individual directory lost files unless had mounted whole hard drive partition directory. in cases, filename stored in file itself. photorec tries recover filename in case, of time photorec can't recover filenames.
