Try something link:
cat <file> | grep ^/

Code:

grep ^/ filename | while read dirname
do
echo $dirname
done

would do

If you want to search only for lines which starts from / then use this code

Code:

for input_dir_row in `cat your_file`
do
echo "$input_dir_row" |grep -s "^/">>/dev/null && echo "$input_dir_row "
done

Code:
