The keyword should be a shell's parameter expansion.

Code:
% cut out shortest suffix (right side)
%% cut out longest suffix (right side)
# cut out shortest prefix (left side)
## cut out shortest prefix (left side)

#### EXAMPLE (the slash is just the delimeter) ####

$> VAR=eins/zwei/drei/vier
$> echo ${VAR%/*}
eins/zwei/drei
$> echo ${VAR%%/*}
eins
$> echo ${VAR#*/}
zwei/drei/vier
$> echo ${VAR##*/}
vier

This book is a good choice regarding such things and many other helpful concepts etc.:
