Progressbar for extracting Basefiles

[Karsten Nordsiek]

Hello to all,

a small problem and I hope you can help me

I want to show a progressbar while extracting the basefile so I have 
done some changes as follows:

changes in /srv/fai/nfsroot/usr/sbin/ftar

Usage: ftar [OPTION] ... SOURCE

    -1                   Use only first tar file matching class name.
    -c class[class]      Define classes (space separated).
    -d                   Delete all files in target before extracting.
    -D                   Create debug output.
    -h                   Show summary of options.
    -p                   Show progress indicator
    -r                   Recursively remove files in target before 
extracting.
    -s source_dir        Look for source files relative to source_dir.
    -t target_dir        Extract files relativ to target_dir.
    -v                   Be verbose. Not yet used.

(Option p added to the Optionlist)

declare Variables:

source=$FAI/files
target=$FAI_ROOT
deletefiles=0
removedir=0
tardone=0
single=0
ignore=0
progress=0

(added progress=0)

Changes in Section extract()

     if [ $progress -eq 1 ]; then

         echo "ftar: extracting $file to $target/$dir" | tr -s '/'
         $catname $file | pv -s $(du -sb $file | awk '{print $1}') | tar 
$xattrs --numeric-owner -C $target/$dir $vflag -xf -
     else
         echo "ftar: extracting $file to $target/$dir" | tr -s '/'
         $catname $file | tar $xattrs --numeric-owner -C $target/$dir 
$vflag -xf -
         tardone=1
         # if option -1 is set, only one class will be used
         [ $single -eq 1 ] && exit 0
     fi

Changes in File /srv/fai/nfsroot/usr/lib/fai/subroutines

changes in Section task_extrabse()

fetch-basefile
     # remember, ftar extracts into $FAI_ROOT by default, so / means 
$FAI_ROOT/
     # copy the base file class based if it exists
     [ -d $FAI/basefiles ] && ftar -1vp -s $FAI/basefiles /
     if [ $? -ne 0 ]; then
         if [ $do_init_tasks -eq 1 ]; then
             ftar -p -1v -c base -s /var/tmp /
         else
                [ -d $NFSROOT/var/tmp ] &&
                ftar -p -1v -c base -s $NFSROOT/var/tmp /
         fi

         # if no base file was extracted, call debootstrap
         if [ ! -d $FAI_ROOT/etc ]; then
             echo "No base file found. Calling debootstrap."
             [ -z "$FAI_DEBOOTSTRAP" ] && die "\$FAI_DEBOOTSTRAP 
undefined. Aborting"
             call_debootstrap $FAI_DEBOOTSTRAP
             task_error 801 $?
         fi
     fi


The file has been extracted but there is no output in Stdout (Terminal)

Let me know if you need more Informations
