One last try , can you run exactly the below from a shell script .

Code:
#!/bin/bash

bash
echo WARNING : THIS DATA HAS BEEN SQLED

#finds all sql files in the home directory and replace sql files containing an underscore with a dash

find / -name "*.sql" | sed -e 's/_/-/g'

#records the number of changes made and outputs them to the user

for i in `ls *-.sql`
do
((n++))
done
echo "Number of conversions is $n"

Is something specific supposed to be entered after the bash? (above the warning)

I managed to increment the count of f using the below code. However, the count that it is displaying isn't correct; it is echoing 1. There has been more than one sql file replaced with a dash. Any ideas?

Code:
#records the number of changes made and outputs them to the user

set sum  = 0
foreach f ("-.sql")
     @ sum++
end
    echo "Number of conversions is " $sum
