Tips n Tricks for Linux

[Satissh S]

I got this from gentoo docs to speed up disk access as well as to activate DMA mode
To test the disk,
# hdparm -tT /dev/hda

To activate safe performance options,
# hdparm -d 1 -A 1 -m 16 -u 1 -a 64 /dev/hda

To activate DMA Alone,
# hdparm -d 1 /dev/hda

Fc5 has irritating alias settings for the root user,
like rm is aliased with rm -i and mv is aliased with mv -i and like that.
This sometimes is very irritating when used on directories with -R option as it asks you for every file.
Check your alias settings with the alias command,
# alias
/**..
stuff
..*/

To get rid of this,
change the rm using
# alias rm='rm'
and you can change back to the old by issuing
# alias rm='rm -i'
if you like the old settings.

Thats beacuse a root user has ultimate control over the system so the interactive mode is set so he can think again before deleting or moving a files...Its been in all versions of Fedora and Redhat not only in FC5..I think its a good thing not a irritating feature

Installing local .ttf fonts for viewing webpages in FF/Mozilla for view in ur LANG

Installing .ttf fonts in Debian/Ubuntu Linux locally

First i downloaded Manorama.ttf(india malayalam language daily) from
*www.hackorama.com/malayalam/fonts/
then for present user,

$cd ~.fonts
$mkdir manorama
Copy Manorama.ttf font into this directory
then,

$ttmkfdir > fonts.dir
$ttmkfdir > fonts.scale
$mkfontscale
$mkfontdir
$xset fp+ $HOME/.fonts/manorama/
$xset fp rehash
Now do an
$fc-cache -fv
Next step is to add the fontpath to our /etc/X11/xorg.conf last of font paths
like this:
> FontPath "/home/prakash/.fonts/manorama/"
Do a
> $fc-cache -fv


Now restart X and try watching in Firefox.
There are better ways to do this especially in redhat fedora.comments are welcome.
and for all users copy ur fonts to /usr/share/fonts/truetype/ dir and do "fc-cache -fv" as su
btwn apt-get install ttmkfdir before trying.

 

[gary4gar]

well fedora we have to just put the fonts into the fonts folder(system>preferences>fonts) then there is a option for the font folder.easy as pie

 

[mehulved]

Can't we do that in Ubuntu by opening Nautilus as sudo and typing fonts:/ and placing the fonts there?

 

[mediator]

Some contribution from me too!

Converting media files

1. Wav to ogg
cmd => "oggenc inputfile.wav -o outputfile.ogg"

2. ogg to wav
cmd => "ogg123 -d wav -f outputfile.wav inputfile.ogg"

3. wav to mp3
cmd => "lame IPfile.wav -o OPfile.mp3"

It requires u to install lame!

i think yes.this hw2 was made by me sometime back.
but earlier nautilus seems to me little buggy with font install.now also the fonts will be shown only after a restart i believe.otherwise u need to check $HOME/.fonts/ for correct install of fonts..

My two Tips!

two tips from me
1)In GNOME(possibly kde and other Desktop Environments too) if some window is very large and it's radio buttons are not accessable to you(not visible),You can get it in GNOME by pressing keyboard ALT key + pressing left mouse button on the software window to move it up or down to get its radio buttons or options.normally i think this problem is faced by ppl having Display resolution lesser than 1024x768.


2) For downloading Linux torrents you can try this site as of now it is free reg:
*www.linuxtracker.org/

And for some people who are uninitated yet:

In the X Window System, middle-clicking by default pastes the contents of the primary buffer at the pointer's position. Many users of two-button mice emulate a three-button mouse by clicking both the right and left buttons simultaneously. Middle-clicks often provide the functionality of an extra button.
.................

On systems with three-button mice, pressing the center button (a middle click) often conveniently maps a commonly-used action or a macro. In the X Window System, middle-clicking by default pastes the contents of the primary buffer at the pointer's position. Many users of two-button mice emulate a three-button mouse by clicking both the right and left buttons simultaneously. Middle-clicks often provide the functionality of an extra button.
Most machines running Unix or a Unix-like operating system run the X Window System which almost always encourages a three-button mouse. X numbers the buttons by convention. This allows user instructions to apply to mice or pointing devices that do not use conventional button placement.

*en.wikipedia.org/wiki/Mouse_%28computing%29
also u can grab a selected text from browser or editor etc to desktop to make a text document.
by selecting text from anwhere and pressing mouse left button dragging to desktop
yes drag-n-drop.

Yes, you too can type cool Unicode characters in your posts, e-mail, signature,
blog, blog comments, etc, using GNOME!

1. Start Accessories/Character Map(gucharmap)
2 Locate interesting characters (see character groups such as "dingbats").
3. Select and copy
4. Paste in your application.

If there is a character you use often,
1. Note down the Unicode codepoint.
2. To type it, press
Ctrl-Shift-<unicode codepoint>

It's recommended to browse available Unicode characters from "gucharmap", or
