工具指令碼 網路編碼

生成結構體網路編碼的perl指令碼(使用google protocal更為通用)：

#

! /usr/bin/perl -w
# usage : proto_hfile proto
my$classmane = "
--@@@@--"; 
for(@ar**
)    
my$out = $in
;    
$out =~ s/(\.\w+)?$/.h/;   #
change suffix name
rename
$in, $in."
.proto
";        #
rename old file, use old name for new file
$in .= "
.proto
";             
unless (open in,"
unless(open out, "
>$out")
print out "
#include \n";
while()
if( /}\s*;/)      
print out $_
;    }
}sub

shell指令碼編碼問題

最近某個指令碼的執行經常導致編碼問題。指令碼從遠端mysql資料庫獲取影片中文名，然後再匯入本機的mysql中。發現由crontab自動執行的時候獲取的影片名稱都是亂碼，但手動執行指令碼卻正常輸出。幾天都是這個問題。今天突然想起以前也有類似問題，在終端執行 echo lang 然後在指令碼中加 ex...
