bash 新手. 請幫我看程式寫的對不對 - Linux

#!/bin/bash
# Passwd file format:
# root:x:0:0:root:/root:/bin/bash
#
# Purpose: Check if remote machines have more than one uid=0 account
#

for host in ma01 ma02

do

COUNT=`ssh $host "cat /etc/passwd | awk '{if ($3 == 0) print $0}' | wc -l "`

if [ $COUNT -gt 1 ]

then

echo "$host : More than one uid 0 account!"

fi

done


不好意思...想請問. 我這樣寫..對不對呢?

謝謝大家了.
