Chapter 1. Inside the Terminal
The Terminal application (/Applications/Utilities) is Mac OS X’s graphical terminal emulator. Inside the Terminal, Unix users will find a familiar command-line environment. In this chapter we describe Terminal’s capabilities and compare them to the corresponding xterm functionality when appropriate. We also highlight key features of another Aqua-native terminal application, iTerm. The chapter concludes with a synopsis of the open command, which you can use to launch Aqua applications from the Terminal.
Mac OS X Shells
Mac OS X comes with the Bourne-Again shell (bash) as the default user shell and also includes the TENEX C shell (tcsh), the Korn shell (ksh), and the Z shell (zsh). The bash, ksh, and zsh are sh-compatible. When tcsh is invoked through the csh link, it behaves much like csh. Similarly, /bin/sh is a hard link to bash, which also reverts to traditional behavior when invoked through this link (see the bash manpage for more information).
The version of bash that ships with Tiger has improved POSIX support over bash implementations that shipped with earlier releases of Mac OS X. Invoking bash with the -posix command-line option changes the default behavior of bash to comply with the POSIX 1003.2 standard in cases where the default behavior differs from this standard.
