So at present our Linux (in the case of CentOS 5.x) How many shells we can use? You can check/etc/shells this file, at least there are several shells that can be used at the bottom:

• /bin/sh (has been replaced by/bin/bash)
• /bin/bash (is the Linux default shell)
• /bin/ksh (KornShell by T-Bell Lab. Developed, compatible with bash)
• /BIN/TCSH (Consolidated C Shell, provides more features)
• /BIN/CSH (has been replaced by/BIN/TCSH)
• /bin/zsh (based on Ksh developed, more powerful shell)

Bash is a shell, and Linux is now the default shell for bash. When you use Ubuntu 10.4.1 to develop Android, the shell is also changed to bash. Mac OS default shell is bash, open terminal, default is bash if enter command in Terminal bash:taylors-mac-mini:~ taylor$ bash
Bash-3.2$ then enter the instructions under bash-3.2$ xxxxxxx, which is actually the equivalent of bash .... sh Run script exit Bash script mode directly exit is back to the user state Error Understanding: Enter bash in the user state to enter bash, In fact, the terminal is bash, do not need to enter the bash entered, in the bash-3.2$ state entered the command is actually a bash script.
