You aren’t checking if the starting directory was aborted only the destination directory. Also you can shorten if - then - fi like this:

d1="$(zenity  --file-selection --title="Bulk Move    Choose starting directory"  --directory)"
[[ "$?" != 0 ]] && exit
d2="$(zenity  --file-selection --title="Bulk Move    Choose destination directory"  --directory)"
[[ "$?" != 0 ]] && exit

This gives double the amount of abort checking with 1 less line of code.

To test the progress bar on any system use this:

$ for i in ./* ; do echo $i ; sleep .1 ;  done | zenity --pulsate --title "Processing " --text "${filename} " --pulsate --auto-close --auto-kill

--pulsate is not supported for this dialogue

Ah there is an error message! --progress is missing to tell zenity a progress bar is desired. So the working script would be:

d1="$(zenity  --file-selection --title="Bulk Move    Choose starting directory" \
    --directory)"
[[ "$?" != 0 ]] && exit

d2="$(zenity  --file-selection --title="Bulk Move    Choose destination     directory" \
    --directory)"
[[ "$?" != 0 ]] && exit

for i in "$d1"/* ; do

    ## filter out the actual file name
    filename=$(basename -- "$i")
    ## the meaty bit
    ffmpeg -i "$i" -c:v libx265 -preset medium -x265-params crf=28 \
        -c:a aac -strict experimental -b:a 128k "$d2"/"${filename%.*}.mkv"

done | zenity --progress --pulsate --title "Processing " \
              --text "ffmpeg - convert files" \
              --pulsate --auto-close --auto-kill

Passing ${filename} to --text option will not update display with each file name processed. If you want this you will need to switch to yad (Yet Another Dialog) which is a super-charged version of zenity:

Although the source code appears in the .gif you can copy and paste in your own script from this Q&A:

⇧ Is it possible to turn off a specific USB port so it doesn't accept any device? Is a for loop using arrays better than using field splitting on a simple variable?  β‡©
