是的，你有拼寫錯誤比較beetwin 2文件，並得到輸出，一些括號丟失各地comparisions和一些間距錯誤。修復它們和腳本將工作：

#!/bin/ksh 
cd /tmp 
FilesDiff=`diff -U 0 /tmp/file1 file2 |grep ^@ |wc -l` 
countnew=`cat /tmp/file1 |wc -l` 
countold=`cat /tmp/file2 |wc -l` 
if (($FilesDiff != 0)) && (($countnew > $countold)) 
then 
    exit 0 
else 
    exit 1 
fi
