SABnzbd URL Bookmarklet (NZBMatrix)

jglemza — Thu, 22 Apr 2010 01:45:01 +0000

Here’s a simple bookmarklet that will take the URL of the current page you’re on and tell SABnzbd to download it. It works great if you’re using NZBMatrix and on the page for the post you’re wanting to download. Perfect for your mobile browser.

javascript:location.href='http://yourhost:8080/api?mode=addurl&name='+encodeURIComponent(location.href)+'&apikey=yourapikey';

Be sure to insert your SABnzbd API key and hostname (or IP address) into the bookmarklet’s code.

Perl Find and Replace One Liner

jglemza — Thu, 21 Jan 2010 01:37:18 +0000

I’m constantly needing a way to easily change a line in a bunch of configuration files. I thought I’d share the way I do it here.

perl -p -i -e 's/oldstring/newstring/g' *

This allows you to use a regular expression and perform the find and replace.

HOWTO: Set the SSHD Idle Timeout

jglemza — Wed, 24 Jun 2009 14:03:37 +0000

Here’s something that I usually forget to change from the default and then get annoyed when my terminal hangs.

As root open your sshd_config file in an editor.
su -
vim /etc/ssh/sshd_config
Add the following lines.
ClientAliveInterval 600
ClientAliveCountMax 3
Restart the sshd process.
service sshd restart

That’s it. That will keep you logged in for 30 minutes at a time without activity. (600 seconds x 3)

M3U Playlist Copy Script

jglemza — Sat, 04 Apr 2009 19:58:00 +0000

A couple of months ago I picked up a Garmin Nuvi 760 on the cheap. As it turns out this great GPS unit can also play music quite well, especially for riding on the motorcycle. The only problem was there was no good way to get playlists on the device that I could find. Enter the following bash script. This script will read an m3u file, copy all associated mp3 files, and generate a new m3u file. Now all I have to do is specifiy m3u files that I exported from Mozilla Songbird and the path to the Garmin’s SD card.

#!/bin/bash
# April 4, 2009
# m3u_cp.sh
#
# Take an m3u file and copy all associated mp3 files
# to a destination directory and generate a new m3u.
#
# Used to copy m3u playlists from computer to Garmin.

if [ $# -lt 2 ]; then
echo "Usage: m3u_cp.sh some.m3u /dst"
exit 0
fi

# Read the m3u file into an array
declare -a M3U
exec 10<"$1"
let count=0

while read LINE <&10; do
M3U[$count]=$LINE
((count++))
done

exec 10>&-

# Determine the m3u's filename
if [[ $1 =~ [^/]*m3u ]]; then
m3u_path="$2/$BASH_REMATCH"
fi

# If playlist arleady exists, delete it
if [ -f "$m3u_path" ]; then
rm -f "$m3u_path"
fi

# Loop through the m3u lines
i=0
while [ $i -lt ${#M3U[@]} ]; do
# The current line is a comment, do nothing with it
if [ ${M3U[$i]:0:1} = "#" ]; then
echo ${M3U[$i]} >> "$m3u_path"

#Current line is a path to an mp3 file
else
# Get the current songs filename
if [[ ${M3U[$i]} =~ [^/]*mp3 ]]; then
song=$BASH_REMATCH
mpath=$( echo ${M3U[$i]} | tr -d '\r' )

# if the song doesn't exist, copy it to the desitnation folder
if [ -f "$2/$song" ]; then
echo File Exists -- $song
else
echo Copying -- $song
cp "$mpath" "$2/$song"
fi

# Write the song in the m3u file
echo $song >> "$m3u_path"
else
echo "The regex for finding the song's filename is fraked up."
fi
fi

let i=i+1
done
exit 0

In the middle of writing this I really started wondering why I used bash. Perl would’ve been a lot easier.

SVN+SSH Howto: Subversion Quick and Simple

jglemza — Wed, 11 Mar 2009 13:57:36 +0000

Here’s a quick and simple way to create a Subversion repository while maintaining security by using SSH and the filesystem permissions.

Create users and add them to a group. There are a bunch of different ways to do this. I am only showing you how to create a group.
groupadd svn-users
Make a directory to house the repository.
mkdir /var/lib/project
Create the repository.
svnadmin create /var/lib/project
Change permissions to allow the group read/write access.
cd /var/lib/project
chgrp svn-users db db/transactions db/write-lock db/revs db/revprops hooks locks
chmod 2770 db db/transactions db/revs db/revprops
chmod 660 db/write-lock
chmod 750 hooks
chmod 770 locks

You can now have your users access the repository over SSH.

svn+ssh://username@server.example.com/var/lib/project

If your clients are on Windows, I recommend using TortoiseSVN.
