Linux users are familiar with OpenSource, and the Free Software Foundation , but many Windows users still have no idea how much free software is available. Sure freshmeat.net is always a good resource for sysadmins and power users, but beginners just want to know how to use their computer, and have no idea what software to use. There are a few nice lists of software when searching Google for "open source software windows": http://www.opensourcewindows.org Top 10 open source Windows apps" http://osswin.sourceforge.net http://www.opensourcelist.org/oss/suggestedapplications.html http://www.myopensource.org And there are free CD's available for download from http://www.theopencd.org and http://www.winlibre.com/en/Articles/Download/index_download.php If you really want more, after searching freshmeat.net and sourceforge.net, check out the directory of software http://directory.fsf.org , which has over 5,000 entries so far. They are not listed by OS, but there are plen...

Did you know, you can receive undergraduate credit for IT Certifications? I was so happy to find out about this. I had taken off a few semesters from school to work on my certs. I had completed my CNE and was working on my MCSE, when I found out I could get credit for some of the exams. The coolest part was, that I didn't really lose any time by getting my certs. I was able to combine the best courses from some very good universities for a more well-rounded education. Ways to Earn Credit Earn undergraduate credit through Excelsior College courses and Excelsior College Exams, credit earned at other regionally accredited institutions, military training, corporate training, technology certification, and more. You may be closer than you think to earning your degree! This looks like an add, but it is more of a personal endorsement. I highly recommend looking into this for any IT person who has not completed their degree yet. You have to keep up with certifications anyway, so why ...

Did you know... that you can take a screen shot of the current window in Windows, or Linux (Gnome) by pressing Alt-PrintScrn? Use Alt-PrintScrn to take a shot of the current window. For the whole screen, try PrintScrn by itself. Windows In any version of Windows, since 95, pressing Alt-PrintScrn copies the current window to the clipboard. To get the image into something useful, you can open paint, and paste it in (ctrl-v). Then select any tool to de-select the "Select" tool, and then re-select it. Mark the area you want to keep, and cut it (ctrl-c) -- that puts the new selection on the clipboard. Now start a new file (save changes - no), shrink the box so your selection fills the box, and paste it in (ctrl-v). Linux Linux is not much different. In Gnome: Press Alt-PrintScrn, and a dialog box appears that prompts the user to save the image to a file. If you have KDE installed you can use KSnapshot...

When you're stuck, just remember "I'm a helpless man" Most commands allow the option "--help", which can then be redirected to "less" (or "more") e.g. cat --help | less To see the man page (more detailed help) for a command type "man" followed by the command e.g. man cat What if you don't remember the name of the command, but you know it was something like lvm? Try apropos apropos lvm What if the man page is the right name, but it displays something about c programming? Use the -a option, and press q until you get the the correct man page. man -a cat For more information look for a HOWTO or other documentation at the Linux Documentation Project -- http://www.tldp.org

The utilites are usually the same ones that are on the CD. Dell likes to make it easier for their support, since users lose CDs, and have no clue on how to download and burn another one. Compaq had a requirement that the SmartStart CD be used in order to install NT, but that is no longer required. If you run fdisk, and reformat the drive, you can reclaim the space. - scottm

How do you get the current date to use in a Linux / Unix shell script? Take a look at this simple backup script: ---------------------------------------------------- #!/bin/sh export   FILE_DATE = `date +%Y%m%d` export   backup_file =backup_ ${ FILE_DATE } .tgz [   !   -d  /opt/backups ]   &&  mkdir -p  /opt/backups tar -zcvf  /opt/backups/ ${ backup_file }  /var/named ---------------------------------------------------- What does that FILE_DATE variable do for me? Well, let's try it on the command line. bash-2.05b$ export FILE_DATE=`date +%Y%m%d` bash-2.05b$ echo $FILE_DATE 20070323 Ah, so that's how we get the current date in a usable format. This method makes the files sortable later. Of course, if you need more than one backup per day, you can always add more date options. Notice a few things about this method of scripting. 1) export, is optional, but it makes the environmet variable available to other s...
