pattern matching for one, # and ## will find first and last occurrence of
text
eg.

$ PATH="file:///etc/some/dir/file"
$ echo ${PATH#*/}
//etc/some/dir/file

$ echo ${PATH##*/}
file
% is used to get the left side # for the right side

it's also used to get numerical data, like the below example gets the size
of the $DISTLIST array
eg..

$ DISTLIST=(ubuntu debian fedora suse)
$ echo ${#DISTLIST[@]}
