Isn't that what the command dirname does? It only does one line at a time, though.

P.S. This is another way:
Code:
sed 's/\/[^\/]*$//'

The final operand (not shown) is the name of your input file.

/ at the end needed?

A couple more ways from the many ways to skin the cat:
Code:
awk '{$NF=_} 1' FS=/ OFS=/ file

Code:
while read line ; do echo "${line%/*}/" ; done < file
