Several ones. One is to use tr:

	... | tr '[A-Z]' '[a-z]' | ...

Or with character classes:

	... | tr '[:upper:]' '[:lower:] | ...

You can also use awk for this task:

	... | awk '{ print tolower($0) }' | ...

You can use this within the awk portion of your script, too.

Or shortened:

	... | awk '{ print tolower }' | ...

But keep in mind: Things like german Umlauts usually won't
be processed correctly.

Those are a few possible solutions. There are more. ;-)
