OK, so whereas symlinks are system functional, aliases are bash script functional and in effect save time and effort initiating programmes that are themselves various versions of bash, and bash scripts, like perl, and python, but then forgive me if I'm wrong but haven't I seen aliases that start programmes, which in themselves are not bash scripts, or is that not so , and in fact there is a bash script but it's embedded in some way so you don't really see it in some file that starts the whole app. John -- John Richard Smith [EMAIL PROTECTED] Want to buy your Pack or Services from MandrakeSoft?

John John, let me give you an example of how aliases work for me. I use WineX to play Windog games under Linux. Sometimes, the commands to start these games are a little, well...long winded. For example, to run Half-Life here, I use the command (all one line): winex /home/darklord/.transgaming/c_drive/SIERRA/Half-Life/hl.exe -console -gl -gldrv Default -w 1024 -game MOD Obviously, typing this in all the time would be a real drag, so I put an alias into /home/darklord/.bashrc (all one line): alias halflife='winex /home/darklord/.transgaming/c_drive/SIERRA/Half-Life/hl.exe -console -gl -gldrv Default -w 1024 -game MOD' Now, I just type in halflife and the game starts. Its just another way to make life easier for yourself... :-) That sounds an interesting idea, so when I run NT now called d4x and because the gui lacks a tab to tell nt that after a cutoff and ISP reconnect it must go reconnect to the web address again, I could set up an alias that would not only put up nt but also save me the bother of having to put up a terminal and type nt -r , which means reconnect, and include it with the command to initiate nt gui as well. Possible ? NT sits in /usr/bin/nt additional command nt -r can I make an alias that combines the two with a simple terminal command nt John -- John Richard Smith [EMAIL PROTECTED] Want to buy your Pack or Services from MandrakeSoft?

John -- John Richard Smith [EMAIL PROTECTED] Well, they allow you to create shortcuts to often used programs wherever you like them to be - they allow programmers to link to libs in nested directory structures, they allow you to create links to actual devices (ex: /dev/hdc -- /dev/cdrom, /dev/hdc -- /dev/dvd, /dev/ttySH012 -- /dev/modem)... Before the advent of large drives, the unix file structure was generally spread out amongst several drives - two or more - so sometimes linking was the best way to access binaries outside of the normal path - hence alleviating path modification... There are other ways of creating links, and links don't always have to be just shortcuts...they can be compiled programs with switches and options already set in them... -- Sat Nov 30 07:50:00 EST 2002 .o0 linux user:267497 0o. |____ | kühn media australia | / \ /| |'-. | http://kma.0catch.com | .\__/ || | | | | _ / `._ \|_|_.-' | stephen kühn | | / \__.`=._) (_ | email: [EMAIL PROTECTED] | |/ ._/ || | email: [EMAIL PROTECTED] | |'. `\ | | |icq: 5483808 | ;/ / | | | | smk ) /_/| |.---.| | mobile: 0410-728-389 | ' `-`' | Berkeley, New South Wales, AU Coralament*Best Grötens*Liebe Grüße*Best Regards*Elkorajn Salutojn You've been infected by the Telescoping Hubble virus.

Re: [newbie] Symbolic links
This example is exactly the reason I didn't offer rm -f as an option--when in root, it does it...period. With rm the user is asked to confirm the delete (and lists what will be deleted) before it is done. Good place for a newbie to make sure they are getting what they asked for.

I've created the same directory structure in Linux Netscape(LNS) as I had in Windows Netscape (WNS) so that I had the right number of Subfolders in each. Taking the 'Unsent Messages' folder as an example, using Midnight Commander, I deleted the LNS file ~/nsmail/Unsent Messages and created a symlink, again using MC, by selecting the equivelent file from WNS directory and using the Symlink command. Then, going back into LNS and selecting the Unsent Message folder the messages originally created under Windows appear. I have not created symlinks for the WNS .snb files, which may be the equivelent to LNS *.summery files. I can't figure out for sure how important they are, but currently seem to be big and worthless. They may have some effect on the linking of follow-up messages, but even this seems to be already working in LNS, so I don't really know. I look forward to now hearing all the reasons why I shouldn't have made these symlinks ;-)

RE: [newbie] symbolic links
I don't know about the symbolic link, but you should be able to find the XFree86-VGA server on the disk. It is probably under /mnt/cdrom/Mandrake/RPMS. Then install the VGA server. I had the same problem with my Voodoo Banshee. Installed the VGA server, then installed the 3DFX drivers and it worked fine.

RE: [newbie] symbolic links
It sounds like you are trying to install the XFree86_3Dfx-XFree86Setup rpm. It requires the VGA16 X server to run. You can install the XFree86-VGA16-3.3.3.1-58mdk.rpm from the install CD. scottw On 15-Aug-99 RReed wrote: Well I can't get the voodoo3 goods to install it keeps saying it can't find vga16.
