Last week I went to Sunburst Internation Music Festival in Bukit Kiara, Kuala Lumpur. Here's what happened:


  • 1:45 pm - Found parking in front of the entrance to Bukit Kiara Equestrian Club

  • 2:45 pm - Gates opened. Kanineh. They said gate will open at 2. Abuden, each place in KL has its own timezone. Kanineh.

  • 3:15 pm - First show - Gerhana Ska Cinta. Sucks big time. And they only play for like, 45 minutes. WTF???

  • 3:20 pm - Second show - Gigi. Memang best giler diarong punya show. Gempak siot. In my opinion, they're the best performer that day. Rock sial.

I, Lazy

I've been very lazy in updating this blog. This is because I spend most of my time at security.org.my, blogging about the Malaysia security scene.

Migrating from Wordpress to Serendipity

For years, this blog has been powered by Wordpress. Prior to this, it was running on a custom weblog engine written by myself. That particular engine lacks quite a number of features, especially spam protection. Everyone else was using wordpress, so i joined the bandwagon. Until now. For years, wordpress have been plagued with security vulnerabilities, and updating it has become such a chore. Besides, I live in the constant fear that this blog will defaced/hacked almost everyday due to the fact that it was running wordpress. So now, I've changed to Serendipity. One of the main reason for choosing Serendipity is that security.org.my has been running on it since July 2007. Since that time, there have been 3 critical vulnerabilities in Wordpress, and Serendipity has one XSS vulnerability in one of its plugin. That is more than enough motivation for me to migrate. Secondly, I like Serendipity's plugins. Installing, deinstalling and updating is damn easy via admin page.

Now for those of you who wants to migrate from Wordpress to Serendipity, Serendipity provides an export function in the admin page. It is very straighforward, everything is imported without any hitch.

bashing the shell

I've been writing quite a large amount of shell scripts for the past few days. Here's are some tips that might be of help.

1. debugging

The simplest way to step through the execution of your shell script is to provide it with the -x option. For example: sh -x myscript.sh

2. array

Yes, shell script can do them. To create an array:

foo=("apple" "orange" "lemon" "durian")

Another example of creating an array automatically:

NETDEVICES="$(cat /proc/net/dev | awk -F: '/[0-9]:/{print $1}')"

To iterate through the array, a for loop will do:
for DEV in $NETDEVICES; do
    echo -n "$DEV"
done


3. printing a specific line from a file
This is a simple head and tail trick:

1st line: cat file.txt | head -n1
2nd line: cat file.txt | head -n2 | tail -n1
3rd line: cat file.txt | head -n3 | tail -n1

and so on...
4. maths
a=1
b=2
c=$(( $a + $b))

shell script however, does not support decimals. For this, I use awk with printf:
a=1.1
b=2.2
c=$(echo $a $b | awk '{printf("%s", ($1+$2))}')


5. string concatenation
a="takizo"
b="memang"
c="handsome"
d=$a" "$b" "$c

or
a="takizo"
b="memang"
c="handsome"
d=${a}" "${b}" "${c}


6. manipulating IFS
IFS stands for internal field separator (or something like that). Example:
a="paul|memang|handsome"
IFS="|"
echo $a

This will replace the IFS with spaces. Of course, for the above, you can use awk:
a="paul|memang|handsome"
echo $a | awk -F | '{ printf("%s %s %s", $1, $2, $3) }'


7. return codes
use $?. Example:
cat /etc/passwd
echo $?
cat /etc/password
echo $?


8. other shell special vars
These are also good for debugging. Try them out for yourself too see what they actually output. Example:
#!/bin/sh
echo "ARG: $1 $2 $3 $4"
echo "script name: $0"
echo "num args: $#"
echo "pid: $$"
echo "options: $-"
echo "args: $*"
echo "args: $@"
echo $?
