Discussed in #116

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.

Fixed in dwarfs-0.7.0-RC3.
