whenever you install itunes || co, you will have installed al required stuff already. so to view the content of your plist file use following batch file:
you need plutil in the folder %commonprogramfiles(x86)%\Apple\Apple Application Support

then you can also convert back to binary with that tool.
show_plist.bat [plist-file]

cd %commonprogramfiles(x86)%\Apple\Apple Application Support
echo now showing "%1"
echo plutil -convert xml1 -o - "%1"
plutil -convert xml1 -o - "%1"


or to convert them directly:
Bin to XML: plutil -convert xml1 file.plist
XML to Bin: plutil -convert binary1 file.plist

first install
apt-get install inotify-tools
maybe also screen to have inotify running with screen in the background

then monitor what is going on. directories after a @ are ignored.

inotifywait -m -r / @/dev @/media @/mnt @/opt @/proc @/root @/sbin @/sys @/tmp @/usr @/bin @/etc @/lib @/var/run/samba/ @/var/cache/samba/

# Make sure we have our PIDDIR, even if it’s on a tmpfs
install -o root -g root -m 755 -d $PIDDIR

for me it did not do all the trick. samba was still trying to access:
/var/lib/samba so:
mv /var/lib/samba/ /var/lib/samba_
cp -ar /var/lib/samba_ /tmp/samba_lib
ln -sf /tmp/samba_lib /var/lib/samba

(this is what I am currently testing… but should work.. so unconfirmed yet 🙂

arr=(“as” “df” 5 kkk “uz z t”);
for ((i=0; i<10; i++));
do echo ${arr[$i]};
done

OUTPUT:

as
df
5
kkk
uz z t

calc if else with floats
a=1.6;b=1.7;if [[ $a < $b ]];then echo $a smaller than $b;fi numbers: i=0 $((i+2)) >> 2

create single images every 25 pic:

ffmpeg -i $1 -r 1 -f image2 out/%05d.png

assemble back all together:
ffmpeg -i out/%05d.png -sameq $2

and as bash script

#!/bin/bash
#create a dir named out by hand, now to lazy
rm out/*
#every 250 /300 one image (10 sec approx)
ffmpeg -i "$1" -r 0.1 -f image2 out/%05d.png
#compile all together with 30fps
ffmpeg -i out/%05d.png -qscale 0 -r 30 "$1.mov"

a=0;ls | while read line; do a=$((a+1)); mv $line `printf “%05d.png\n” $a`;done

multiple VOB file with multiple audio tracks into avi
we want to have only VOB 4 to 7

for i in `seq 4 7`; do c=`ls VTS_0$i*| grep VOB| grep -v _0.VOB | tr “\n” ” “`;cat $c > $i.VOB;done

for i in `seq 4 7`;do ffmpeg -i $i.VOB -vcodec libxvid -y -acodec libmp3lame -ac 2 -map 0:0 -map 0:2 -map 0:1 -vb 2M -ar 44100 -ab 128 $i.avi;done

unpack: rootfs
cat rootfs.gz | lzma -d | cpio -id -H newc
or
cat rootfs.gz | gunzip -c | cpio -id -H newc

pack:

dd if=/dev/zero of=rootfs1 bs=1k count=8192
mke2fs -q -F -m 0 -i 1024 rootfs1

mkdir -p rfs
sudo mount -t ext2 -o loop rootfs1 rfs
cd rfs
tar –exclude=”*/lib*\.a” –exclude=”*/man/*” –exclude=”*/include/*” -cpf – * | \
sudo tar -C rfs -xf –
// sudo chown -h -R 0:0 rfs

find ./rfs | cpio -o -H newc | gzip -9 > rootfs.gz
sudo umount rfs

//gzip -9 -c rootfs1 > rootfs.gz

better to unpack with
cpio -id --no-absolute-filenames
or you will smash your linux…

auspacken:

gunzip < initrd.img | cpio -i –make-directories

einpacken:

find ./ | cpio -H newc -o > initrd.cpio

gzip initrd.cpio

mv initrd.cpio.gz initrd.img
