dir2sfs with xz compression, How can I? (Solved)

[oldyeller]

Hello Everyone,

Can dir2sfs be edited to and or have xz compression?

Code: Select all

#!/bin/bash

. /etc/DISTRO_SPECS

t=`echo "$1" | sed "s/\/$//"`
z=`echo "$1" | sed "s/\/$//"`

if [ ! -d "$t" ];then

  echo "error: no valid folder specified!"
  exit 0

fi

### if no _versionnummer in the end, get it from system
check=`echo $t | sed "s/\(.*\)_[0-9][0-9][0-9]$/\1/"`

#echo --- $check

if [ "$check" == "$t" ];then

  v=$DISTRO_VERSION
  z="${check}_$v"

fi
#echo $t - $z


if [ -f "$z.sfs" ];then

  echo "$z.sfs already exists, refusing to overwrite it!"
  exit 0

fi

mksquashfs "$t" "$z.sfs"
md5sum "$z.sfs" > "$z.sfs-md5.txt"
sync


echo
echo
s=`du -m "$z.sfs" | sed "s/\s.*//"`
echo "created: $z.sfs ( $s MB )"
echo "created: $z.sfs-md5.txt"
echo
echo "...byebye..."
echo

Adding

Code: Select all

 -comp xz

to the mksquashfs line ought to do it I think.

Thanks that worked save 3m off my sfs.

This is the code from Saluki/Carolina, select gz or xz

Code: Select all

#!/bin/bash

t=`echo "$1" | sed "s/\/$//"`
z=`echo "$1" | sed "s/\/$//"`

if [ ! -d "$t" ];then

  echo "error: no valid folder specified!"
  exit 0

fi

### if no _versionnummer in the end, get it from system
check=`echo $t | sed "s/\(.*\)_[0-9][0-9][0-9]$/\1/"`

#echo --- $check


#echo $t - $z


if [ -f "$z.sfs" ];then

  yad --title "sfs exists" --text "$z.sfs already exists, refusing to overwrite it!" --button=ok:0
  exit 0

fi

yad --title "Choose Compression Type" --button=XZ:0 --button=GZIP:1 --text "Choose which algorthim to compress the sfs with.
Chosing XZ here will give you a smaller iso but
may be slower than GZIP on very lowspec machines."
[ $? = 0 ] && COMP="-comp xz"

mksquashfs "$t" "$z.sfs" $COMP |while read -n 50 LINE ; do 
echo $LINE |egrep '[0-9]\%'| cut -f1 -d% |awk '{print $NF}'|grep -v '\.' ;done | \
Xdialog --title "Building Squashfile " --gauge "Building Squashfile. Please Wait..." 0 0
md5sum "$z.sfs" > "$z.sfs-md5.txt"
sync


echo

s=`du -m "$z.sfs" | sed "s/\s.*//"`
echo "created: $z.sfs ( $s MB )"
echo "created: $z.sfs-md5.txt"

Hi Geoffrey,

Will give this a go. Thanks

I think you will save some more with this one:

Code: Select all

-b 1024k -comp xz -Xbcj x86 

Gives the best compression xz can do for squashfs.

Thank you,
I just tried and the result is impressive.
For a 509 MB folder, I get 149MB with -comp xz, and 129MB with -b 1024k -comp xz -Xbcj x86

Bookmarked.
Asri did a pet for adrive, similar as dir2sfs. Somebody would have any idea where to retrieve it ?

pas de réponse.. le résultat d'une compression dépend aussi du fichier à comprimer..
blank is the main character
When 1000 blanks, they are replaced by a flag '1000 blanks to write' flag is only 2 or 3 characters
