In our example, there is a file named DVWA-master.zip, 10752 bytes long. root omer: ~ / Downloads # shred -vuf -iteration=30 DVWA-master.zip Let’s see how the shred command deletes a file. The reason why this process is not used normally An assumption is made that if you write too much data to the disc, the life of the disc will be shortened. Shreds the file, shuffles and overwrites 10-20-30 or more new random data, making it non-recyclable. According to the rules you will write to the command parameters, it writes random data bits to the addresses where the file is located. The shred command does the deletion by going to the addresses on the disk itself. ![]() To do this, there is the shred command that comes preinstalled with Linux. Whenever new information is searched for to be written to disk, it is overwritten. In fact, the data you think you deleted is still on your disk. Only your operating system’s location catalogue, those addresses are empty information is encoded. Whichever of the above-mentioned methods you use, your files are not physically deleted from the disk space where they were written. Note: Deletion is irreversible in the command line. You can also delete from the command line with the rm command.Depending on your Operating System, there may also be a method to delete ( Shift + Delete) the file without sending it to the Trash.Right-click on the file in the desktop environment and select one of the DELETE-Send to Trash options. If you are using a visual interface in the control system, you will definitely know the words Recycle Bin, Trash can.You can remove a directory with the rmdir command. You can’t just rm a directory by default, you’ll need to add the -r flag (recursive) to remove all the files and any subdirectories it may have. f or force option tells rm to remove all files, whether they are write protected or not, without prompting the user (as long as you have the appropriate permissions).Īdding the -i flag like many of the other commands, will give you a prompt on whether you want to actually remove the files or directories. Now if you don’t care about any of that, you can absolutely remove a bunch of files. If a directory is write-protected it will also not be easily removed. Write-protected files will prompt you for confirmation before deleting them. ![]() Once they are gone, they are gone for good, so be careful.įortunately there are some safety measures put into place, so the average joe can’t just remove a bunch of important files. Take caution when using rm, there is no magical trash can that you can fish out removed files. The rm (remove) command is used to delete files and directories. ![]() ![]() To remove files you can use the rm command. Now I think we have too many files, let’s remove some files.
