Works for me.
Code:

-rw-r--r--  1 root  wheel   411 Jul 27 10:58 3.txt
-rw-r--r--  1 root  wheel   552 Jul 27 10:58 4.txt
-rw-r--r--  1 root  wheel  1371 Jul 27 10:57 file
-rw-r--r--  1 root  wheel     0 Jul 27 11:04 test.file
# ls -l $1 | awk 'NR>1{min=min?min:$5}{if(min >$5)min=$5}{if(max<$5)max=$5;suma+=$5}END{printf "min=%d max=%d suma=%d", min,max,suma}'
min=0 max=1371 suma=2742[11:04:49]#

NAME

       shells - shell database

SYNOPSIS

       /etc/shells

DESCRIPTION

       The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
       shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.

       A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by  the  routines
       which search the file. Blank lines are also ignored.

       The  following  default	shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh,
       /bin/tcsh,  /bin/zsh,  /sbin/jsh,  /sbin/sh,  /usr/bin/bash,  /usr/bin/csh,  /usr/bin/jsh,  /usr/bin/ksh,  /usr/bin/pfcsh,  /usr/bin/pfksh,
       /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh. Note that /etc/shells overrides the default list.

       Invalid shells in /etc/shells may cause unexpected behavior (such as being unable to log in by way of ftp(1)).

FILES

       /etc/shells	       lists shells on system
