dwarfsextract option (command) of the read operation (process) for yad (progressbar) ?

[fwn0]

I would like to have the progress of extracting dwarf archives displayed graphically. Is there any way to send the unpacking process to a pipe?
I have tried something similar 7 zip or fa:

# Unpacking package
"$7zz" x archive.7z -aoa -oc:"$1" >> "$progress_pipe" \
2>&1 >> "$progress_pipe" & echo "$!" >> "$main_proc_id"

# Wait here and it returns exit status "${?}"
# It's stderr redirected to /dev/null for prevent messages from the kill
wait "$(<"$main_proc_id")" 2>/dev/null

if [ "$?" = "0" ]; then
	echo "#Installation completed" >> "$progress_pipe"
	kill "$main_pid" >"$main_proc_id" 2>/dev/null
else
	echo "#Installation error" >> "$progress_pipe"
	echo $? >> "$progress_pipe" 
	kill "$main_pid" >"$main_proc_id" 2>/dev/null
fi

or: 
# Unpacking from the archive
"$fa" x "$dir"/archive.fa -o+ -dp"$1" >> "$progress_pipe" \
2>&1 >> "$progress_pipe" & echo "$!" >> "$main_proc_id"

# Wait here and it returns exit status "${?}"
# It's stderr redirected to /dev/null for prevent messages from the kill
wait "$(<"$main_proc_id")" 2>/dev/null

if [ "$?" = "0" ]; then
	echo "#Installation completed" >> "$progress_pipe"
	kill "$main_pid" 2>/dev/null >"$main_proc_id"
else
	echo "#Installation error" >> "$progress_pipe"
	kill "$main_pid" 2>/dev/null >"$main_proc_id"
fi

which works fine, but for dwarfsextract it cannot capture this process.

Yep, dwarfsextract currently has no way of displaying or sending progress information.

It was easy enough to add, though, so it's now in the latest release candidate dwarfs-0.7.0-RC3.

You need to supply the --stdout-progress flag to enable progress output. I've tested this with zenity, so I would assume it works just fine with yad as well:

dwarfsextract -i rasp-norm2.dwarfs -o tmp --stdout-progress \
    | zenity --progress --auto-close --no-cancel --time-remaining
