While Deleting to delete a snapshot, i typed:
zpool destroy zfsdiskpool@Satand got:
cannot open 'zfsdiskpool@Sat': invalid character '@' in pool nameThis is because to delete snapshots in ZFS, you should use ‘zfs destroy’ instead of ‘zpool destroy’. DOH!
zfs destroy zfsdiskpool@SatHandbrake is a fantastic tool for (among other uses), converting videos into mobile formats. It is extremely easy to use and can usually get a video properly converted in just a few clicks. To get Videos encoded for use on my phone, I use the “iPhone & iPod Touch” preset. It will convert your video to .mp4 as well as scale it down to a consumable size. This format will work on any smartphone I’ve seen.
My issue is that when converting a folder full of videos, I don’t want to have to use the gui to add a bunch of videos to the queue one by one. It’s a very clicky process. This simple bash script will walk handbrake through all the files in a selected folder (and it’s subfolders). This uses the find command to traverse recursively through a directory structure. It will place the transcoded file in the same folder as it’s source and change it’s extension to “.mp4″.
Usage: handbrakefolder.sh [FOLDER]
Run handbrake on all the files contained in [FOLDER]. (the current directory by default)
#!/bin/bash
#
# Change this to specify a different handbrake preset. You can list them by running: "HandBrakeCLI --preset-list"
#
PRESET="iPhone & iPod Touch"
if [ -z "$1" ] ; then
TRANSCODEDIR="."
else
TRANSCODEDIR="$1"
fi
find "$TRANSCODEDIR"/* -type f -exec bash -c 'HandBrakeCLI -i "$1" -o "${1%\.*}".mp4 --preset="$PRESET"' __ {} \;Save that into a .sh file like “handbrakefolder.sh” and grant it the execute permission (chmod +x handbrakefolder.sh).
Thanks to Vinnie and http://mywiki.wooledge.org/UsingFind for their help in this.
Now you can simply execute this script against a folder containing your video files. like this:
For a folder structure like this:
Videos
-> show1
vid1.avi
-> show2
-> season 1
ep1.avi
ep2.avi
-> season 2
ep1.avi
ep2.avi
-> show3
vid1.avi
vid2.avi
hostname% handbrakefolder.sh Videos
...
....
...
When done, it will look like this:
Videos
-> show1
vid1.avi
vid1.mp4
-> show2
-> season 1
ep1.avi
ep1.mp4
ep2.avi
ep2.mp4
-> season 2
ep1.avi
ep1.mp4
ep2.avi
ep2.mp4
-> show3
vid1.avi
vid1.mp4
vid2.avi
vid2.mp4I was bored… So this is a little bash script i wrote that will write zero’s to a hard disk infinately until you press CTRL+C. It uses dcfldd instead of plain dd because i like the progress output it provides.
#!/bin/bash
echo -e "Which disk would you like to wipe out? (sda, sdb, sdc)? \c"
read DISK
read -p "You picked "$DISK", are you sure? (y/n)" -n 1
if [[ $REPLY =~ ^[Yy]$ ]]
then
C=1
for (( ; ; ))
do
echo -e "\nStarting zero Sweep number "$C" ..."
dcfldd if=/dev/zero of=/dev/$DISK
echo "Zero's written to Disk "$C" time(s)"
echo "[ hit CTRL+C to stop ]"
let C=C+1
done
fi
There are a million different tutorials out there on how to convert a MKV file into a format that an xbox360 will play. You may have found, like i did, that most of them use 50 different questionable pieces of software to manipulate individual tracks and separate the mkv, etc, etc… I think those are ridiculous.
Please read the FAQ regarding xbox360 file format compatibility. It may help you pick better options for your particular files than the general ones i offer below.
The solution is simple: Use Avidemux.
Once avidemux is finished with your file, it’s ready to go.
UPDATED 8-10-10:
This script has been superceeded by its newer version at http://www.surlyjake.com/shell-scripting/script-to-run-handbrake-recursively-through-a-folder-tree/. The new version features all of the previous features, but can also traverse recursively through a folder structure.
#!/bin/bash
if [ -z "$1" ] ; then
TRANSCODEDIR="."
else
TRANSCODEDIR="$1"
fi
for file in "$TRANSCODEDIR"/*
do
HandBrakeCLI -i "${file}" -o "${file}.mp4" --preset="iPhone & iPod Touch"""
doneSave that into a .sh file like “handbrakefolder.sh”
