lsort.exe (stored in lsort.zip - 25,309 bytes) a "quicksort" for ANSI files up to 1GB with any line lengths.

Usage is lsort {flags} {infile} {outfile}
      or [some command] | lsort {flags}
	{flags} are -b, -g, -i, -n, -r, -u, +#, -o [outfile] where
	-b means ignore leading whitespace
	-g means start compare at first char after greater-than (>)
	-i means ignore case
	-n means sort numerically (implies -b)
	-r means reverse sort (descending)
	-u means remove duplicate lines
	+# means start compare at character # (applied before -b or -g)
	-o [outfile] write result to [outfile]
		useful when input is stdin & output isn't to be stdout
	{infile} is overwritten unless -o or {outfile} given
		if no {infile}, input is stdin, output is stdout
	{outfile} is optional; same as (but overrides) -o
		no -o & no {outfile} means outfile same as infile
		and infile saved as *.BAK; but
		when input is stdin, output is stdout (unless -o given)
