Tips and Tricks for a BASH Power Prompt

From setting the window title to show the last run command (filtered), saving your history and keeping multi-session history intact, resetting the color/cursor/highlighting of errant color-emitting commands, this prompt does more than meets the eye and is extremely fast.

Don’t have much time or just don’t care? No problem, this is a simple copy and paste of 2 lines and thats all there is to it!

PortaPutty Auto-Reconnecting SSH Tunnels on an Encrypted TrueCrypt Portable USB Key w GPG

Ok I just came back up to write the intro.. I’m trying to keep it short to avoid getting bogged down by the coolness of each step. Here is what goes on. When I logon to my XP machine at work, I bring my usb key and plug it in first. On logging a window pops up first and it’s a password prompt to mount my encrypted drive leonardo. It also checks a keyfile that is located on my usb key, but all I do now is type in my password. That causes my encrypted folder to be accessible to me like a normal drive, and it autoruns a startup batch file.

The batch file causes Portable versions of Firefox (all my bookmarks, my settings) to load, and launches Portable Mozilla Thunderbird (IMAP makes this work well), which is my favorite program (great GPG features and open-source!). Also Some Adobe CS4 software is loaded from the hard drive, like DreamWeaver. In the background, a service we created executes a PortaPuttY plink command to create forwarded tunnels from various remote servers and accounts, all using key-based encryption. These tunnels are automatically reconnected if they are disconnected, meaning you can use a socks 5 if you want or even better!

Custom bash_profile for Advanced Shell Users

Looking for some advanced uses for the shell? Here is some of my best. The shell is where 70% of my work takes place, and I have at least one terminal open almost 100% of the time, for viewing tailing color-coded logs, and of course for the SSH Tunnels that I use to route various networking through, like my email. So I decided that to standardize and create a bash_profile containing the most time-saving and helpful functions that I could use on all the various hosting environments would really be some sweet sugar, so here is my constant Work-in-progress.

It works for all shells I encounter, including BackTrack, Debian, Knoppix, Arch Linux, etc. Also works for many hosting environments I use including DreamHost, HostGator, WiredTree, and pretty much any linux VPS.

I also rely on this heavily from within shell scripts I write to access all the functions and stuff in this .bash_profile, and to do that I just do like:

#!/bin/bash
 
source ~/.bash_profile &>/dev/nulll
 
pm "PM is a function to output nice messages with color"
yn "Are you enjoying the shell" && pm "Thats great!" || pm "Perhaps you're better suited for DOS"
yn "Show Calendar" && aa_calendar
yn "Show Fortune" && aa_fortune

Advanced WordPress wp-config.php Tweaks

The bottom line for this article is that I want to make WordPress as fast, secure, and easy to install, run, and manage because I am using it more and more for client production sites, I will work for days in order to solve an issue so that I never have to spend time on that issue again. Time is money in this industry and that is ultimately (time) what there is to gain by tweaking WordPress.

Note: I spent no time on readability, this is primarily a read the code and figure it out article.. This is for advanced users looking for a reference or discussion and for those of you looking to advance. Feedback would be great if you make it that far..

Chmod, Umask, Stat, Fileperms, and File Permissions

Unix file permissions are one of the more difficult subjects to grasp.. Well, ok maybe “grasp” isn’t the word.. Master is the right word.. Unix file permissions is a hard topic to fully master, mainly I think because there aren’t many instances when a computer user encounters them. I’ve done a lot of research on it the past couple weeks… and now here’s everything I’ve learned so far.. cuz you guys AskApache Regs Rock!

Wget Trick to Download from Restrictive Sites

Before

After trick
I am often logged in to my servers via SSH, and I need to download a file like a WordPress plugin. I’ve noticed many sites now employ a means of blocking robots like wget from accessing their files. Most of the time they use .htaccess to do this. So a permanent workaround has wget mimick a normal browser.
