display YAD progress bar while finding files

[Roelof Berkepeis]

hello all,

I'm new to YAD and i want to build some application which finds all JPG files (or other) in a folder and its subfolders, display the found file names in a YAD dialog (i'm using --list for this) and perform some string filtering functions on each file name to finally build an SQL statement : this SQL will be written to a file, which the user later can execute to insert these file names (and their dates/sizes/etc) into a database. I somewhat succeeded : the finding process is indeed shown in a YAD list by this script :

#! /bin/bash

myNR=0

fcAmp(){

sed 's/&/&/g' # sanitize ampersand char (due to yad error message)

}

fcMY(){

while read data; do

echo "$myNR$data"

myNR=$((myNR + 1)) # file counter prefix number

done

}

find /home/roelof/Desktop/FBset/ -name '*.jpg' | \

fcAmp | \

fcMY | \

yad \

--notebook \

--list \

--column "Files" \

--title "Some App Title" \

--fontname "mono 10" \

--width 600 \

--height 300 & \

yad --progress --pulsate --auto-close --auto-kill --button gtk-cancel:1

#---------------------

However, the last line doesn't work properly : i expect the progress bar displays the real progress (of the list-building, while finding files), but it shows "0 %" all the time .. I also wonder how to get such progress bar into the "notebook"; my script gives a second YAD window.

#! /bin/bash

myNR=0

fcMY(){
while read data; do

    myNR=$((myNR + 1))               # file counter prefix number
    echo "$myNR"
    echo "$data" | sed 's/&/&/g' # sanitize ampersand char (due to yad error message)
    echo "#Found $myNR item(s)"      # third line here goes the text for the progress bar


done | tee >(lisT)

    # A way to kill the progress (well, sort of)
    echo ""
    echo ""
    echo 100 # Printing 100 closes the progress dialog
}

function lisT(){
    (yad \
    --notebook \
    --list --column "Num" \
    --column "Files" \
    --column "hidden" \

    --title "Some App Title" \
    --fontname "mono 10" \
    --width 600 \

    --height 300 \
    --hide-column="3" \
    --print-column="2" \
    --separator="" > /home/roelof/Desktop/result.txt # write the result(s) to a file
    if [[ $? == 1 ]]; then
        rm -f /home/roelof/Desktop/result.txt
        exit 0
    fi) || exit
}

find /home/roelof/Desktop/FBset/ -name '*.jpg' | \
fcMY | awk 'NR % 3 == 0;fflush()' | yad --progress --pulsate --auto-close --auto-kill --button gtk-cancel:1 --on-top

# awk - prints every third line and flushes to stdout
#---------------------

Something like that would do. It's a bit ugly (most likely), because I haven't slept much last night...
