You can use program like OpenOffice.org office application to open Ms-Word, Excel, and PowerPoint files under Linux, FreeBSD and other Unixish oses. If you are looking for command line based utilities then try out catdoc or catppt: catdoc : Reads MS-Word file and puts its content as plain text on standard output. catdoc. Parameters: network interface and IP address; Without parameters: status of all configured network interfaces on the system. Use the route command to view or configure routing table within the Linux kernel. Without parameters: displays the kernel routing table. 9. Configuring Networking with Command-Line Utilities. 10. I am trying to convert a *.ppt file in to *.pdf file using linux command, I am using libreoffice for Ubuntu-12.04 server and it is working fine and the command is following sudo /usr/bin/libreoffice --headless --convert-to pdf:writer_pdf_Export /var/www/...../1234.pptx --outdir /var/www/..../. I installed libreoffice on. 'netstat'. It can show a lot of information about the current state of your host's networking subsystem – such as routing-table entries, active connections, ports and protocols, or statistics for the active Network Interfaces; Example: $ netstat -i; It's not a 'privileged' command – any user can execute Linux's 'netstat' utility. 'whois'. System Administration and Forensics. Focus on host based forensics from a Linux platform. Covers: Basic Linux Commands; Some administration issues pertinent to forensics. The use of Caine for host-based forensics; The theory behind host-based forensics. Uses “linuxzoo.net" for practical exercises. Pre-requisites for this. Linux Device Drivers (continued). Manage data flow between a user program and devices; A self-contained component (add/remove from kernel); A user can access the device via file name in /dev , e.g. /dev/lp0. General implementation steps. Understand the device characteristic and supported commands. Map device. Cheatsheet: http://ppt.cc/pBABN. Outline. • Introduction to NCHC. • Introduction to LINUX. • Basic LINUX commands. • How to edit documents on LINUX. • What is Queuing system? • How to submit a Job to our queuing system(LSF). 2. Sometimes multiple flavors implemented – shells; Primarily fetches a command from user and executes it. 2.6. Microsoft Windows is GUI with CLI “command" shell; Apple Mac OS X is “Aqua" GUI interface with UNIX kernel underneath and shells available; Unix and Linux have CLI with optional GUI interfaces (CDE, KDE,. Types of UNIX The Linux PenguinThere are many different versions of UNIX, although they share common similarities. The most popular varieties of UNIX are Sun Solaris, GNU/ Linux, and MacOS X. Here in the School, we use Solaris on our servers and workstations, and Fedora Linux on the servers and desktop PCs.
