What are the three most common command shells in linux?

Answer 1

The original is sh. So that cant be ignored. Many of the commands on a linux system are actually shell scripts which start with the line of
#!/bin/sh
Popular variations of that would be bash and ksh

Another line of shells is for people who use C programming alot. That would be csh, or tcsh

zsh is a shell which includes the best features of bash and tcsh and is becoming popular for personal use. But since it cant be gauranteed to be on every machine its not a good idea to write scripts in it for distribution.

Personally, I like MUDsh

Answer 2

It's a two sided coin. I run Linux 95% of the time, Windows 5% of the time. I don't like being a Microsoft Hostage, I don't like crashing computer systems and I don't like reinstall it all the time. The con, it doesn't have billions of programs to install, like Windows and second if you are a gamer then keep Windows around using dual boot so you can play all the available games. If you are new to Linux, try some of the Linux LiveCDs and test them out before you install it. If you decide on Ubuntu I would recommend Mint Linux (Ubuntu Based). Ubuntu does not install proprietary hardware drivers so you have to tweak it to your system. Linux can do many things that Windows can't do very well, it's really a programmers and hackers dream with some of the files i has that can be installed for free, but at he same time is a great Desktop for computer users in general.

Answer 3

It depends on the function of the system. I am a server admin, so I would guess top, nano (or vi), and grep. http://www.linuxboards.org/showthread.php?t=1596

Two of my guesses would be:

ls
cd

my third would probably be editor related, like vi.

Bash, Z Shell, C Shell.
