You should quote the pattern for the shell, e.g.:

grep 'gdk*' file.txt

You can see what's going on by using the shell command 'set -x' before 
running 'grep'.

Given file.txt with three lines:

/usr/local/lib/gdk-pixbuf-2.0
empty
/usr/local/lib/libgd2

When I do:

grep gdk file.txt
this results in : /usr/local/lib/gdk-pixbuf-2.0

Which looks ok for me.

When I do:

grep  gdk* file.txt
this results in : /usr/local/lib/gdk-pixbuf-2
                  /usr/local/lib/libgd2.0

This looks like then '*' eats the 'k'
from 'gdk*' and looks for 'gd'' instead of 'gdk*'.
Or equivalent to grep  gd* file.txt
Or equivalent to grep  gd file.txt

grep   gdk.* file.txt
this results in : /usr/local/lib/gdk-pixbuf-2.0

Which looks ok for me.
Either now the point is eaten or the point is correctly replaced by 'any 
character'



grep is grep-3.8 and linked with


Can you please verify if this is a bug or anything in my thinking is 
wrong beacuse I have overlooked something?
