檔案格式導致cgi無法運行

今天有客戶回函：perl編寫的cgi程式無法運行,報錯，查看日誌：
[Mon Aug 22 16:12:57 2011] [error] [client 59.57.251.34] Premature end of script headers: aaa.cgi
[Mon Aug 22 16:12:58 2011] [error] [client 59.57.251.34] Premature end of script headers: aaa.cgi
[Mon Aug 22 16:12:58 2011] [error] [client 59.57.251.34] Premature end of script headers: aaa.cgi

[Mon Aug 22 16:13:21 2011] [error] [client 59.57.251.34] Premature end of script headers: aaa.cgi
[Mon Aug 22 16:13:21 2011] [error] [client 59.57.251.34] Premature end of script headers: aaa.cgi
伺服器端直接運行報錯：
[root@localhost cgi-bin]# ./aaa.cgi
-bash: ./aaa.cgi: /usr/bin/perl^M: bad interpreter: 沒有那個檔案或目錄
root@localhost cgi-bin]# dos2unix aaa.cgi
 
重新核實，ok!
分析：該檔案格式不對，非二進位格式，導致。。。
