Advanced Command-Line Editing

: Today I passed my 117-201 exam and now I play a little bit with the Vi
: key bindings on Zsh. In Bash you can set them with set -o vi, and in Zsh you
: can set them additionally with setopt vi.
:
: I want to get to the point of command line editing above the basic
: tab complete and history browsing, searching and minor corrections. So I
: start witch a little example:
:
: I want to rename a file with the following naming scheme:
:
: someID_filename.txt to filename.txt
:
: After my fulminant efficient Vim key combination for table editing, (see this article)
: I challenge everybody to find the shortest key combination to fulfill this
: task.
:
: I start with an self-deprating solution:
:
: First I type:
: mv someID_filname.txt
:
: Now the count begins:
:
: <Space><Esc>T_y$$p<Enter>
:
: This makes a total of 9 characters which i have to store in my brain. As I want
: to have my head free for more complicated tasks, of course this has to
: be optimized dramatically :)
:
: Have fun.

GoogleEarth Freezes With Actual Ati-Drivers (No More)

There is a library missing, libGL.so.1 see this site for instructions.

Edit: Everything works fine for me now with latest googleearth (4.2.0198.2451 (beta)), no need to copy this library anymore as googleearth starts then in software-emulation mode.

Insert Current Date In Vim

If you write a ToDo list or a schedule in vim, you probably want to insert the current date or the date after one week from now. Here is how to do:

:r !date

or to add one week to the current date:

:r !date -d “today 1 week”

enjoy :)

Move files beginning with an hyphen

This one is easy, as escaping does not work you have to prefix the filename with two hyphens like so:

mv — -some_silly_filename_with_an_hyphen_before_it

Cannot connect with ipw2000 module

Building a new kernel i couldn’t connect annymore to my wlan-router, allthough i had the same configuration as my other kernel. Whell, almost, under Cryptographic options i build the AES cipher algorithms as module therefore the ieee80211_crypt_ccmp module could not find it , though i made a depmod. It gave me the errormessage:

ieee80211_crypt_ccmp: could not allocate crypto API aes

So apparently you have to build this into the kernel for wlan

Append yanked and deleted lines to registers in vim

Man, this never has an ending, so you already yank some files like this into a register:

Vim commandline

Today i have my LPIC 101 exam, and while learning i tripped over this two examples:

vi +”set number” somefile.txt

vi +/sometext somefile.txt

The first one opens a file and numbers it and the second one opens a file and highlights the searchterm.

mysqlimport: Error: The table ’sometable’ is full, when using table: sometable

If this error drives you mad on Gentoo, change this line in your /etc/mysql/my.cnf (if you use inoDB):

innodb_data_file_path = ibdata1:10M:autoextend:max:128M

and delete the :max:128M part or raise it up to your liking.
