批量转换文件编码GBK to utf-8

find ＋ iconv的组合会强制给文件添加.cpp.cpp类似的后缀，所以组合mv指令 ，放在shell脚本里运行

#!/bin/bash
if [ "$#" != "2" ]; then
echo "Usage: `basename $0` dir filter"
exit
fi
dir=$1
filter=$2
echo $1
for file in `find $dir -name "$2"`; do
echo "$file"
echo "iconv -f gbk -t utf8  $file >  $file"
iconv -f gbk -t utf8  $file > $file.in
echo "mv $file.in $file"
mv $file.in $file
done

将该文件命名为iconv.shchmod +x iconv.sh ./iconvsh ./src *.cpp运行

大字符集转为小字符集，会有内容丢失，并且报错，如utf-8有中文时转为ascii
