Re: [Astlinux-devel] Adding a "spinner" indicator when e2fsck is working

[Michael K. <mic...@ip...>]

Do you really need a spinner? 
Couldn't you just echo a comment that e2fsk is working and this could take a REAL long time so don't panic?
You could then have another comment after e2fsk saying its done!

Here is a working test of a "spinner" function:
https://gist.github.com/abelbeck/40c1da054ae6740f03e09ef70452cf70

In our case, instead of the test examples:
--
date
sleep 2
date
sleep 10
--
we would have:
--
e2fsck -y $ASTURW >/dev/null
status=$?
--

Seems to work, the question is whether it is worth adding.
