22Aug10 Sample ASP.NET code that works in Cloud Sites

Uploading the following 3 files will result in a bare bones ASP.NET site that functions within Rackspace Cloud Sites. It would be possible to trim these down further, especially the web.config, however this is what I came up with through Visual Studio with minimal editing to the resultant files.

web.config:

17Aug10 Sorting files by datestamp in Bash

You would think there were a function in Linux already that would do this.  The following command will sort all files in a directory and all subdirectories for the past 14 days by datestamp.

bash$ find . -mtime -14 -type f | while read line; do echo -n `ls -l --time-style='+%s %F %T' "$line" | awk '{print $6,$7,$8}'`; echo " $line"; done | sort | cut -d ' ' -f 1 --complement

16Aug10 Securing WordPress on a shared host

The following articles contain details on securing your WordPress installation on a shared hosting service, specifically Rackspace Cloud Sites.  This post will change as more resources are compiled:

On a shared hosting service running suexec, there should be no reason to have global permissions on a php site:

Backup, Backup, Backup!  Just 2 of many possible backup scripts.

If the unfortunate does occur, these three links contain information on recovering. Due to the possibility of backdoors being injected within your sites though, the safest option would be to restore from one of your backups. You do keep backups, right?

16Aug10 Simple Bash Loop Constructs

Many times it is useful to write an ad-hoc program within bash to accomplish a task. Most of an ad-hoc script is composed of text formatting as well as a loop to get things running. The most useful loop structure that I find in my experience is a do while loop as follows:

bash$ ls | while read line; do cat $line; done >out.txt

As can be seen from this command line, most of the heavy lifting is performed within the while loop.  This while loop will perform the given command on each line that is input into the construct and your bash command can further redirect its output to a file or a command that follows.  You may notice this construct in many of the bash one-liners that I post here in the future.  xargs can usually be used to perform repeated tasks as well, however I find that this chain of commands is more flexible.
