Introduction to Seismic Unix: Understanding Unix and Unix-like Operating Systems
This lesson covers the fundamental aspects of Seismic Unix, focusing on Unix and Unix-like operating systems, such as Linux, Free BSD, and Mac OS X. Key topics include basic login/logout processes, the concept of the shell, and how to use commands like `echo $SHELL`. We will also explore various text editors such as vi, vim, emacs, pico, nano, and discuss the Unix directory structure. Additional topics include the Unix help system with the `man` command, understanding input/output redirection, and background processes. A quick reference card for Unix commands will be included.
