Some Common Shell Commands That You Should Know

On Linux you  have to prefix the command with "sudo" keyword to run it with root privileges. It is similar to getting Administrator rights in Windows. The “root” user on UNIX platforms has full system access, like the “Administrator” user on Windows. Your Windows file system is located at /mnt/c in the Bash shell environment.
Here are some basic commands of Linux that are similar to Windows. Bash indicates the Linux command and DOS is it's Windows analoge.
  • Change Directory: cd in Bash, cd or  chdir in DOS
  • List Contents of Directory:  ls in Bash, dir in DOS
  • Move or Rename a File: mv in Bash, move and  rename in DOS
  • Copy a File: cp in Bash,  copy in DOS
  • Delete a File: rm in Bash,  del or erase in DOS
  • Create a Directory:  mkdir in Bash, mkdir in DOS
  • Use a Text Editor: vi or nano in Bash,  edit in DOS
To install packages in Linux, you would have to use the apt command and couple it with the sudo keyword. Here are the apt-get commands you’ll need to know:
  • Download Updated Information About Available Packages: sudo apt update
  • Install an Application Package:  sudo apt install packagename (Replace “packagename” with the package’s name.)
  • Uninstall an Application Package:  sudo apt remove packagename (Replace “packagename” with the package’s name.)
  • Search for Available Packages:  sudo apt search word (Replace “word” with a word you want to search package names and descriptions for.)
  • Download and Install the Latest Versions of Your Installed Packages: sudo apt upgrade
This lesson is over now. Godspeed!

Troubleshooting Error: "Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?"

While installing the openssh-server package, I encountered this error. If you have come across the same problem follow the given steps and you may be all okay in less than a minute. First type this command sudo apt edit-sources in the linux command line. Enter your password if it prompts you. Now, it will prompt you to select an editor. Choose the Nano Text Editor by typing and entering "1" or it will directly open the editor window. Add the "s" at the exact location to replace "http" from "https" and switching to a secure server. Now run the following command, sudo apt-get update This will fix everything. You can follow me on Kali Linux Forums .
