Upgrading to FC5

Time to upgrade to FC5…

First we upgrade our system to the latest FC4 updates:
yum upgrade

Upgrade the fedora release:
rpm -Uvh http://download.fedora.redhat.com/pub/fedora/linux/core/5/i386/os/Fedora/RPMS/fedora-release-5-5.noarch.rpm

Upgrade the yum:
yum upgrade yum

And now time for the full system upgrade:
yum upgrade

Wait……….do a reboot and you are up and running.

appending the bash history

One common problem with the default settings of bash or the defaults settings of your bash_profile ~/.bashrc is the bash_history.

When you logout from your shell all the commands you entered there are writteen to the bash_history. Hmmm what happens when you logout from 2 or more shells ? Yes the last history list is written = you loose what you typed in the others shells you closed.

Instead of overwriting the history list to the history file you can append it.

shopt -s histappend
export HISTSIZE=4096

We also change the default HISTSIZE from 500 lines to 4096

Add the commands you your ~/.bashrc ~/.bash_profile and you are up and running

Intermediate pressure test

What do you do when you want to check your first stage ?

Option 1: Send it to GKAM

Option 2:

Step 1: Get the IP test guage from GKAM 🙂
Step 2: Attach it to the low-pressure BC hose

The IP pressure from the first stage of Ray is 10.5 bar. And has a fast response when you breath from the octupus. Looks ok to me….
