軟體簡介:
　
Unix for Mac OS X Users unlocks the powerful capabilities of Unix that
underlie Mac OS X, teaching how to use command-line syntax to perform
common tasks such as file management, data entry, and text manipulation.
The course teaches Unix from the ground up, starting with the basics of
the command line and graduating to powerful, advanced tools like grep,
sed, and xargs. The course shows how to enter commands in Terminal to
create, move, copy, and delete files and folders; change file ownership
and permissions; view and stop command and application processes; find
and edit data within files; and use command-line shortcuts to speed up
workflow. Exercise files accompany the course.

‧Moving around the file system
‧Creating and reading files
‧Copying, moving, renaming, and deleting files and directories
‧Creating hard links and symbolic links
‧Understanding user identity, file ownership, and sudo
‧Setting file permissions with alpha and octal notation

‧Using the command history
‧Directing input and output
‧Configuring the Unix working environment
‧Searching and replacing using grep and regular expressions
‧Manipulating text with tr, sed, and cut
