• Mac OS X comes with iconv utility that can convert text between encodings. Run the following command in Terminal to convert a gb2312 chinese text file to utf-8:

  iconv -f cp936 -t utf-8 chinese-gb2312.txt > chinese-utf8.txt

• To list the encodings that iconv supports:

  iconv -l

以下是自己写的使用shell递归转换一个文件目录下的文件格式到utf-8格式的脚本

#!/bin/bash  
   
function encode() 
{
	iconv -f cp936 -t utf-8 "$1" > test
	# iconv -f iso8859-15 -t utf8 "$1" > test;
	cat test > "$1";
}

function walk()  
{  
  for file in `ls $1`  
  do  
    local path=$1"/"$file  
    if [ -d $path ]  
     then  
      echo "DIR $path"  
      walk $path  
    else  
      echo "FILE $path"  
      encode $path
    fi  	
  done  
}  
   
if [ $# -ne 1 ]  
then  
  echo "USAGE: $0 TOP_DIR"  
else  
  walk $1  
fi
