Unary Operator Message - Linux/Unix
I have this code to check the largest files by bytes. Whenever I run it, I keep getting an error message "unary operator expected"

Code:
for i in *
do
if
set -- $(ls -ls "$i")

alias filesize='ls -lS'

[ "$i" -gt $filesize ]
then
echo $1: $5 bytes
fi
done

LFC_SETFSIZEG(3)					       LFC Library Functions						  LFC_SETFSIZEG(3)

NAME

       lfc_setfsizeg - set filesize for a regular file having the given GUID; set also last modification time to the current time

SYNOPSIS

       #include <sys/types.h>
       #include "lfc_api.h"

       int lfc_setfsizeg (const char *guid, u_signed64 filesize, const char *csumtype, char *csumvalue)

DESCRIPTION

       lfc_setfsizeg  sets  the  filesize for a regular file having the given GUID; set also the last modification time to the current time.  This
       function should only be called by the stager after the last write operation has been performed on the file.  The file is identified by  its
       guid.

       guid   specifies the Grid Unique IDentifier.

       csumtype
	      specifies the type of checksum. Valid types are:

	      CS     standard 32 bits checksum

	      AD     Adler 32 bits checksum

	      MD     MD5 128 bits checksum

RETURN VALUE

       This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.

ERRORS

       EFAULT	    guid is a NULL pointer.

       EINVAL	    The  length  of  the  guid exceeds CA_MAXGUIDLEN or the length of the csumtype exceeds 2 or csumtype is an unknown type or the
		    length of the csumvalue exceeds 32.

       SENOSHOST    Host unknown.

       SENOSSERV    Service unknown.

       SECOMERR     Communication error.

       ENSNACT	    Name server is not running or is being shutdown.
