Can this be modified so it’s output can be used in gxmessage ?

#!/bin/bash
# 
# Show size of dir using gxmessage 
# 
clear
a=`du /home/andy/Downloads/`         # 
echo "$a"         # The quoted variable preserves whitespace.

P.S. How come # in front are stripped out ?

I’ve edited your post so it displays properly. Edit it yourself to see what I did. Those 3 characters that look like quotes are accents (below Escape) and I made it straight “text”.

I do not see any difference.

I would like to use gxmessage to show the output.

Here is what I would like to use, assuming you have gxmessage installed.

gxmessage -fg red -font ‘sans 20’ -timeout 3 ’ BACKING UP FILES FOR UBUNTU_MATE 16.04.3 LTS’

gxmessage lets you change font size,color,time it displays, etc.

I'm not sure your goal. When I run that gxmessage command, up pops this message:

My last post was addressing how "#" was being stripped out of the post here.

Thanks for the help with displaying # characters.

My goals is to display the result of du /home/andy/Downloads/ in a format that has an adjustable font and will also shutdown after a set amount of time.
