Retrieve directory path from full file path through sh


I have a file abcd.txt which has contents in the form of full path file names i.e.
$home> vi abcd.txt

Now I want to retrieve only the directory path name for each row

How to get the same through shell script?
I have done till now:
while read file
  cd  <here need the directory path for each row>
  .. do some common operation ...
done < abcd.txt

Previously Franklin suggested for getting only the file name to use:

Please help!Smilie

$ for F in /a/b/c/r1.txt /q/w/e/r2.txt /z/x/c/r3.txt; do echo ${F%/*}/; done

Another way: Remove the base filename you found with ${file##*/}. This method does not delete the trailing soidus.

for file in "/a/b/c/r1.txt" "/q/w/e/r2.txt" "/z/x/c/r3.txt"
        echo "${file%%${file##*/}}"
