Title: xdotool how to select desktop send F5 and return?

It sounds simple; xdotool selects desktop, simulates F5 key press and returns focus to calling window / program.

After googling though it doesn’t sound simple anymore.

I need to do this from bash / gnome-shell.

Any ideas?


This project is related to this Q&A where the icons drop off the left screen into a black whole because of different sized monitors:

Thanks to Podesta’s help I created this code:

TestIcons () {

    [[ $TestSeconds == "" ]] || [[ $TestSeconds == 0 ]] && TestSeconds=5

    local i Position File
    for (( i=0; i<${#IconsArr[@]}; i=i+ICON_FLD_CNT )) ; do
        File="$ICONS_DIR"/"${IconsArr[((i+ICON_NAME_NDX))]}"
        Position="${IconsArr[((i+ICON_COL_NDX))]},${IconsArr[((i+ICON_ROW_NDX))]}"
        gvfs-set-attribute -t string "$File" \
                'metadata::nautilus-icon-position' "$Position"
    done

    wmctrl -k on        # Show desktop
    xdotool key F5      # Refresh desktop (show icon new positions)
    sleep $TestSeconds  # Pause for view
    wmctrl -k off       # Restore windows

    for (( i=0; i<${#OldIconsArr[@]}; i=i+ICON_FLD_CNT )) ; do
        File="$ICONS_DIR"/"${OldIconsArr[((i+ICON_NAME_NDX))]}"
        Position="${OldIconsArr[((i+ICON_COL_NDX))]},${OldIconsArr[((i+ICON_ROW_NDX))]}"
        gvfs-set-attribute -t string "$File" \
                'metadata::nautilus-icon-position' "$Position"

    done

    wmctrl -k on        # Show desktop
    xdotool key F5      # Refresh desktop (show icon new positions)
    wmctrl -k off       # Restore windows

} # TestIcons

This is what the screen looks like:
