splitting up of absolute filepath


I am using the bash shell on suse.I need to split the absolute file path
into filename and directory path.

eg: /cas/43fg/temp/sample.txt

i want to split the above into
sample.txt(file) and /cas/43fg/temp(directory path)

I want to do this by using shell commands.Would anyone help ?

A solution :
file=$(basename $full_path)
dir=$(dirname $full_path)

pth=$( echo ${full_path%/*} )
file=$( echo ${full_path##/*/} )

pth=$( echo $full_path | sed "s,/[^/]*$,," )
file=$( echo $full_path | sed "s,/.*/,," )

pth=$( echo ${full_path%/*} )

Remove the shortest match from / to end of the input string

file=$( echo ${full_path##/*/} )

Remove the longest match /*/ from the start of the string

Why the $(..) and the echo ?

This will work as well.
