Linux Basic File Operations

1. Basic File Operations

   • ls: List files in a directory
   • cp: Copy a file
   • mv: Rename ("move") a file
   • rm: Delete ("remove") a file
   • ln: create links (alternate names) to a file
   • shred: completely erase a file when the file is deleted
     • The operating system does not completely erase a file when the file is deleted. The file could be recovered by third party forensic tools. But we can use the SHRED command to overwrite a file to make it almost impossible for it to be recovered. The file is overwritten three times, by default,which can be changed by using the -n option
