My Bash prompt info & links

tw001_tw — Mon, 23 Jan 2006 05:20:07 GMT

I'm keeping this here for my own reference.
Of course, you can use it to if you want.
I might add more links later on.

Below you will find a complete list of all special sequences,
and color codes.

Sequence Description
\a The ASCII bell character (you can also type \007)
\d Date in "Wed Sep 06" format
\e ASCII escape character (you can also type \033)
\h First part of hostname (such as "mybox")
\H Full hostname (such as "mybox.mydomain.com")
\j The number of processes you've suspended in this shell by hitting ^Z
\l The name of the shell's terminal device (such as "ttyp4")
\n Newline
\r Carriage return
\s The name of the shell executable (such as "bash")
\t Time in 24-hour format (such as "23:01:01")
\T Time in 12-hour format (such as "11:01:01")
\@ Time in 12-hour format with am/pm
\u Your username
\v Version of bash (such as 2.04)
\V Bash version, including patchlevel
\w Current working directory (such as "/home/drobbins")
\W The "basename" of the current working directory (such as "drobbins")
\! Current command's position in the history buffer
\# Command number (this will count up at each prompt, as long as you type something)
\$ If you are not root, inserts a "$"; if you are root, you get a "#"
\xxx Inserts an ASCII character based on three-digit number xxx (replace unused digits with zeros, such as "\007")
\\ A backslash
\[ This sequence should appear before a sequence of characters that don't move the cursor (like color escape sequences). This allows bash to calculate word wrapping correctly.
\] This sequence should appear after a sequence of non-printing characters.

A quick step-by-step on installing MPlayer

tw001_tw — Sat, 21 Jan 2006 18:17:59 GMT

This is FAR from an all enclusive how-to. Its a simple, and direct
step-by-step, with minimal options or optimizations. Your distro
may have anather way, this is the manual way (or atleast how I do it
manually).

All versions noted are current at the time of this writting. (1.21.06)

1st step - software you need.

MPlayer v1.0pre7try2 source - The program.
Download here:
ftp://ftp5.mplayerhq.hu/mplayer/releases/MPlayer-1.0pre7try2.tar.bz2

all-20050412.tar.bz2 - Codecs.
Download here:
ftp://ftp5.mplayerhq.hu/mplayer/releases/codecs/all-20050412.tar.bz2

font-arial-iso-8859-1.tar.bz2 - Fonts.
Download here:
ftp://ftp5.mplayerhq.hu/mplayer/releases/fonts/font-arial-iso-8859-1.tar.bz2

Corelian-1.1.tar.bz2 - Skins.
Download here:
ftp://ftp5.mplayerhq.hu/mplayer/Skin/Corelian-1.1.tar.bz2

NOTE: The 4 above links are direct to mplayer server.
These are the ones I use. If you want different skins, check
for newer files, or just want to read the official docs,
HERE IS THIER DOWNLOAD PAGE:
http://www.mplayerhq.hu/homepage/design7/dload.html

2nd step - Installation divided in to 4 parts: installation of
codecs, program, fonts, & skin.

codecs: Extract the file "all-20050412.tar.bz2" and copy its contents
into the directory /usr/local/lib/codecs/ . Do this BEFORE compiling
and installing MPlayer v1.0pre7try2.

program: Extract the file "MPlayer v1.0pre7try2" and enter that new
directory. Now type:
./configure --enable-gui
make
make install (or 'checkinstall' would be better if your running Slack).

fonts: Extract the files in font-arial-iso-8859-1.tar.bz2. This gives
you a few directories with fonts in them. Copy 1 set of fonts to the
directory /usr/local/share/mplayer/font/

skins: Extract the files in Corelian-1.1.tar.bz2. Copy these files to
the directory /usr/local/share/mplayer/Skin/default/

3rd step - Starting the program

Start the console and type ' gmplayer'. If all went well, it should be up
and running. If you use gmplayer frequently, you can make a link to the
exacutable on your desktop. Make it point to /usr/local/bin/gmplayer

4th step - Basic configuration

I usually only have to change 2 things in the configuration for it to work.

right click on the player (not the movie window), and click on 'preferences'.
On the video tab, I elect to use the " xv X11/Xv " video driver.

Also, under the Misc. tab, I have to tell it which drive my DVD player is. I
change it to /dev/hdd - as that is my dvd reader.

Byond this, the default configuration seems to work well for me.

Good luck!!!!!!

Some notes I made regarding matrox frame buffer in Gentoo - kernel 2.6.11

tw001_tw — Fri, 20 Jan 2006 04:26:19 GMT

#1 - Using the Matrox framebuffer
TIP: Do NOT, and I repeat, DO NOT, compile into your kernel "vesafb', or "vesafb-tng" if you choose "Matrox Acceleration".

cd /usr/src/linux
make menuconfig

This is what you need (how I did it):
Under Device Drivers -> Graphics support[*] Support for frame buffer devices[*] Enable Video Mode Handling Helpers[*] Matrox acceleration[*] G100/G200/G400/G450/G550 support[*] Multihead support

Under Device Drivers -> Graphics support -> Console Display driver support
--- VGA text console[*] Video mode selection support[*] Framebuffer Console support[*] Select compiled-in fonts[*] VGA 8x8 font[*] VGA 8x16 font

Under Device Drivers -> Graphics support -> Logo Configuration[*] Bootup logo[*] Standard 224-color Linux logo

Then in /etc/lilo.conf add the line : append = "video=matroxfb:vesa:0x117".. like this:

# Gentoo
image = /boot/vmlinuz-2.6.11-gentoo-r6
root = /dev/sdb1
label = Gentoo
read-only
append = "video=matroxfb:vesa:0x117"
# append = "video=vesafb:mtrr,ywrap,1024x768-16@60"
# Gentoo

Run /sbin/lilo, and reboot - all should be well

#2 - Using the vesa framebuffer
TIP: Do NOT, and I repeat, DO NOT, compile into your kernel "matrox acceleration', if you choose to use the vesafs!

cd /usr/src/linux
make menuconfig

This is what you need (how I did it):
[*] VESA VGA graphics support
VESA driver type (vesafb-tng) --->
(1024x768@60) VESA default mode

Then in /etc/lilo.conf add the line : append = "video=vesafb:mtrr,ywrap,1024x768-16@60"
# Gentoo
image = /boot/vmlinuz-2.6.11-gentoo-r6
root = /dev/sdb1
label = Gentoo
read-only
# append = "video=matroxfb:vesa:0x117"
append = "video=vesafb:mtrr,ywrap,1024x768-16@60"
# Gentoo

Run /sbin/lilo, and reboot - all should be well

slow DNS resolution in mozilla & firefox

tw001_tw — Mon, 16 Jan 2006 16:20:11 GMT

After suffering for weeks on a clean install of slackware 10.2 - I had terriblly slow DNS resolution times.
Ranging from 10 seconds, to what seemed forever.

I found a nice solution here at LQ.

Turn off IP6:
Open up Mozilla or Firefox and type in 'about:config' in the address bar
Scroll down to "network.dns.disableIPv6", it's defaulted to a value of false
Double-click on that line and change it to "true"
Close your browser, launch it again and it should work.

(I take no credit for this solution
I even copy/pasted the answer (I did clean it up and simplify it though).)
Original solution was given by: chiquitomuir
