UNIX Power Tools

The classic publication on "... the best free software for UNIX power users" has been updated and expanded with POSIX utilities, more 'bash' and 'tsch' tools, updated scripts and programs. Software is pre-compiled for common UNIX platforms and Linux. This densely packed user's guide and programming reference leads you through the logical progression of in/out logging, home directory organization and terminal setup. In each case provides scripts, techniques, optimization pointers, code, very good explanations and rationale. Explains the shell environment, variables and relationships, shows how shells interpret your input, then guides you through optimized and customized shell prompts. Includes the most extensive discussion of command line use and optimization we have seen to date. Examines aliasing, job control and I/O redirection. Very good focus on file system navigation, wild cards, finding files with 'find', renaming, linking, archiving, backup, and of course answers the eternal question, "Where did I put that?" One entire chapter deals with file security, ownership and sharing, very good. Continues to emphasize file management with searching and pattern matching techniques (regular expressions), file compare and count utilities. Provides vi tips and custom command techniques, includes Emacs, sed and batch editing.
