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. ;-)
