how perform grep operation on all files in a directory

Question

Working with xenserver, and I want to perform a command on each file that is in a directory, grepping some stuff out of the output of the command and appending it in a file.

Answer 1

If you want to do multiple commands, you could use:

for I in `ls *.sql`
do
    grep "foo" $I >> foo.log
    grep "bar" $I >> bar.log
done
