Compile Vim 7.4 on CENTOS 6 or RHEL 6 box --enable-gui=yes :help csapprox+gui

The following article covers the steps required to build and install VIM 7.4 on CentOS 6/RHEL 6 system. It was necessary to install VIM 7.3+ version on my CentOS 6 system in order to use VIM spf13

remove any installed vim packages

yum remove $(rpm -qa | grep ^vim)

download VIM version 7.4 from here: ftp://ftp.vim.org/pub/vim/unix/

mkdir -p /opt/pkgs

cd /opt/pkgs

wget ftp://ftp.vim.org/pub/vim/unix/vim-7.4.tar.bz2

tar jxvf vim-*.tar.bz2

rm -f vim-*.tar.bz2

cd vim*

set-up build environment

yum install gcc make ncurses-devel

configure and build VIM sources

./configure --disable-selinux \

--enable-multibyte \

--with-features=huge \

--with-modified-by=Ndosh \

--enable-gui=yes



make

make install

re-hash the environment

hash -r

One magic line to setup awesomeness for VIM editor in OSX [lots of plugins]

On you MAC OSX box run the following command in a terminal prompt for all the awesomeness.

$ curl http://j.mp/spf13-vim3 -L -o - | sh

A. Use ifconfig command. It is used to remove virtual interfaces or network aliases.
Ifconfig is used to configure the kernel-resident network interfaces. It is used at boot time to set up interfaces as necessary. After that, it is usually only needed when debugging or when system tuning is needed.
Type the command to remove eth0:1:
# ifconfig eth0:1 down

http://stackoverflow.com/questions/40317/force-unmount-of-nfs-mounted-directory

If the NFS server disappeared and you can't get it back online, one trick that I use is to add an alias to the interface with the IP of the NFS server (in this example, 192.0.2.55). In Linux the command for that is something roughly like:

ifconfig eth0:fakenfs 192.0.2.55 netmask 255.255.255.255  

Where 192.0.2.55 is the IP of the NFS server that went away. You should then be able to ping the address, and you should also be able to unmount the filesystem (use unmount -f). You should then destroy the aliased interface so you no longer route traffic to the old NFS server to yourself.
On FreeBSD and similar operating systems, the command would be something like:

ifconfig em0 alias 192.0.2.55 netmask 255.255.255.255  

And then to remove it:

ifconfig em0 delete 192.0.2.55  

man ifconfig(8) for more!

	1   A combination of ifconfig eth0:fakenfs ...' and umount -f -l /my/mount/dir' solved the problem for me. – pts Jan 16 '10 at 15:41

Colors in terminal bash command prompt for LINUX - Screen Virtual terminals - CW

cwrapper.sourceforge.net/README

1. What is cw(color wrapper)?

cw is a non-intrusive real-time ANSI color wrapper for common unix-based

commands on GNU/linux.  cw is designed to simulate the environment of the

commands being executed, so that if a person types 'du', 'df', 'ping', etc.

in their shell it will automatically color the output in real-time according

to a definition file containing the color format desired.  cw has support for

wildcard match coloring, tokenized coloring, headers/footers, case scenario

coloring, command line dependent definition coloring, and includes over 50

pre-made definition files.

CRM CONFIGURE
- crm configure show - show the current configuration
- crm configure edit - should not do live edits, do as i say,not as I do
- crm node online $node (how to turn it on)
- crm node standby $node (how to turn it off
- crm resouce cleanup $resouce (if there are errors after running a status, it might help if you run cleanup)
- crm resource start $resouce
- crm resource stop $resource
- crm resource promote $resource
- crm resource migrate $resource (problem with migrate, Fencing)

FENCING
- fencing tells a resource to try to stay on particular node or to avoid a particular node
- crm resource migrate causes fenscing
