Linux in a Nutshell by Jessica Hekman
"Linux in a Nutshell" covers the core commands available on common Linux distributions. It provides a complete reference to all user, programming, administration, and networking commands. Contents include: programming, system administration, and user commands with complete lists of options; LILO and Loadlin (boot) options; shell syntax and variables for the bash, csh, and tcsh shells; pattern matching; Emacs and vi editing commands; sed and gawk commands; common configuration tasks for the GNOME and KDE desktops and the fvwm2 window manager; and Red Hat and Debian package managers. New material in the third edition includes common configuration tasks for the GNOME and KDE desktops and the fvwm2 window manager, the dpkg Debian package manager, an expanded investigation of the rpm Red Hat package manager and CVS, and many new commands. "Linux in a Nutshell" delivers everything needed for common, day-to-day use. It also covers a wide range of GNU tools for Unix users who have GNU versions of standard Unix tools.
