wolph / to_images.sh
Created March 9, 2014 16:59
Script to automatically convert directories to sparse images on OS X. Since I have noticed a pretty obvious slowdown in OS X when having lots (many millions) of files on the filesystem, this has given me quite a significant speedup.
#!/bin/bash -e
function image_all(){
echo "Processing $1"
test -d "$1" || return 1
cd "$1"
for i in *; do
if [ "$i" == "utils" ]; then
continue

Simple script to copy zfs vdevs (partitions) from one zpool to another with a progress bar :)
#!/bin/sh
source=$1
dest=$2
snapshot=$3
size=$(zfs send -nP $source@$snapshot 2>&1 | grep size | awk '{print $2}')
echo "$source@$snapshot -> $dest: $size"
zfs send $source@$snapshot | pv --timer --progress --eta --rate --average-rate --bytes --size $size --cursor --name $source | zfs receive -Fvu $dest
