Installing Ubuntu Starting and exploring Ubuntu Installing and Removing Applications Playing with BASH Abhinav Upadhyay B.Tech (4^{th} Year) Dept. of IT ## A short voyage towards the evolution of *Nix 0 to install/upgrade, 0 to remove ## Playing with BASH BASH → Bourne Again Shell (The default Shell of all Linux distros) Shell → ## Playing with BASH ## Trying out some commands – psswd → Change your directories - date – uname → knowing about your system - cal → calendar – bc → the BASH calculator ## Playing with BASH ## Understanding Linux Commands – External Commands → Normal programs whose location

them dominate the space: Bash, Csh, Zsh, Fish and many more! All shells originate from the Bourne Shell, called sh. "Bourne" because its creator was Steve Bourne. Bash means Bourne-again shell not open source, and Bash was created in 1989 to create a free alternative for the GNU project and the Free Software Foundation. Since projects had to pay to use the Bourne shell, Bash became very popular If you use a Mac, try opening your Mac terminal. That by default is running ZSH. (or, pre-Catalina, Bash) You can set up your system to run any kind of shell, for example I use the Fish shell. Each single
