Recursive tasks unix style

I had to update a php file and each php file is under a different folder. A folder represents a site I'm updating:

site1.com

site2.net

site3.com.tw

so, I had to:

for j in *; do echo $j; cd $j/html && (for i in `find . -name "configuration.php"` ; do chflags noschg $i; perl -pi.bak -e 's/apache/apache2/g' $i; chflags schg $i; done; ) && cd ../.. ; done

I needed two loops as find would crap out because of the extra deep directory structure. Or maybe there's a flag to tell find not to go eny deeper than 1?

You might be wondering what's the chflags is for. It's an extra measure it won't get overwritten by Apache even if the the owner is root:wheel.

This is not an official indication that they do use cultured earthworms. If you also check out the end of the HTML page, they have lots of keywords put in for search engines. I wonder if this is allowed by Google?

Mac Mini Project

I'm planning to build a media center PC using Mac Mini. Here are the things to digest:

The howto by Chris
The hardware that connects the mini to a TV
The software that rips the DVDs and save them to a file

Convert FLV files to MPEG

to convert to "keys me" videos and the like

ffmpeg -i video.flv -ab 56 -ar 22050 -b 500 -s 320x240 test.mpg

Been getting flack about me moderating a guy's sub-forum at an all-female dominated community board. It's hard to act "professional" when some people act like children.

k700i & VGA Mode lines

Just got a new phone! It's Sony Ericsson k700i. It's an old phone but it's the phone I really want.

Just saw this on /.

I know I'll get moderated as a troll again because I suggest using Linux over Windows, but

Modeline "800x480" 40 800 864 928 1088 480 481 484 509 +hsync

Will do the trick for X. No drivers necessary.

It might come in handy someday.

Ultra Electro Magnetic Top!

I was checking out the Eraserheads entry at Wikipedia to see the albums they've made. I have their first album, titled "UltraElectroMagneticPop!". The Wiki entry didn't say where the name of the album came from so I tried editing it.

The Wiki hanged for a while till I decided to save it again.

Check it out! Hopefully, my update was accurate enough:

Unix: Old dog, new tricks

Renaming files in linux:

To rename all files ending in ".old" to ".new", use the following:
for i in *.old; do echo mv $i `basename $i .old`.new; done

To remove the first few characters from a file, you can try the following:
for i in *; do echo mv $i `echo $i | tr -d "wqy"`; done

To rename/change uppercase to lowercase in current directory:
for i in `ls`; do mv $i `echo $i | tr '[A-Z]' '[a-z]'`; done

To rename/change uppercase to lowercase excluding directories:
for i in `find . -type f -print`; do
base=`basename $i`;
echo mv $i `dirname $i`/`echo $base | tr '[a-z]' '[A-Z]'`;
done

To rename/change uppercase to lowercase directories:
for i in `find . -print -maxdepth 1 -type d | grep [a-z]`; do
echo mv $i `echo $i | tr '[a-z]' '[A-Z]'`;
done

Remove markup tags in files:
cat filename.xml |sed -e "s/<\/*tagname>//gi"
cat filename.xml |sed -e "s/<\/*tagName>//g"

iptables brute force rule

Saw this on /. today:

iptables -A INPUT -i eth0 -p tcp --dport 22 -m state --state NEW -j SSH_Brute_Force
iptables -A SSH_Brute_Force -m recent --name SSH --set --rsource
iptables -A SSH_Brute_Force -m recent ! --rcheck --seconds 60 --hitcount 4 --name SSH --rsource -j RETURN
iptables -A SSH_Brute_Force -m limit --limit 3/min -j LOG --log-prefix "SSH Brute Force Attempt: "
iptables -A SSH_Brute_Force -p tcp -j REJECT

4 ssh connections within a second causes a 3 minute ban. I wonder if there's a FreeBSD equivalent.
