	Here is a program called tolower, that takes an argument and
returns it in lowercase.  Compile it and use the csh script:

	foreach file (*)
	mv $file  `tolower $file`
	end

======== tolower.c ==========

/*	tolower.c

	converts argument to lowercase on stdout
*/

#include <stdio.h>

main(argc,argv)
	int argc; char **argv;
 {
	if (argc > 1) {lowers(argv[1]); printf("%s",argv[1]); exit(0);}
	else exit(1);
	}

lowers(str)
	char *str;
{
	char tolower();
	for (; *str; str++) *str = tolower(*str);
	}

char tolower(chr)
	char chr;
{
	if (chr>='A'&& chr<='Z') return chr-'A'+'a';
	else return chr;
	}
