tr, cut, newbie stuff



Hello,
	Please respond privately to this message. I'm trying to figure out tr,
sort, for a project. 
	The first task is with tr, i have to take a file, run tr on it, and
translate all uppercase characters in that file to lowercase, then store
that translated output somewhere else. Everytime i try this i get cintax
errors.
	For sort, i have another field with 8 colon separated fields. The last
field is a numeric cost field, i have to sort the various items by cost,
and store that sorted output in another file. Again, when i execute this
command i don't get any cintax errors, but the output file is not sorted.

Finally, i have to use the grep utility to search for files that have two
links and again store that output in another file.
	Any help on this is greatly appreciated.
Thanks.
Dave.
