for i in `cat input` - Dangerous Backticks

Use while loop instead:
Code:
#!/bin/bash

while read line
do
        c=$( program ${line} | wc -l )
        line=${line/:/ }
        line=${line/-/ }
        echo "${line} ${c}"
done < input

       an exit status of 1 on EOF and always prints at least a new-line. It is often used within shell files to read from the user's terminal.

EXIT STATUS

       Exit status is:

       0        Successful completion

       >0       End-of-file on input.
