我是靠谱客的博主小巧季节，最近开发中收集的这篇文章主要介绍shell实现字符编码转换工具分享，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

复制代码代码如下:

#!/bin/bash

: << mark
转码工具，支持UTF-8转GBK和GBK转UTF-8

mark

#set -x

scode="gbk"
dcode="utf-8"

function Usage()
{
cat << EOF
Usage: conv [OPTIONS] [DIR]
[-u] GBK to UTF-8
[-g] UTF-8 to GBK
EOF
exit 1
}

#将当前目录下所有普通文件进行转码 GBK to UTF-8
function g2u()
{
local dir=$1
printf "Convering $dir ......"
for file in $(ls $dir)
do
file="$dir/$file"
if [ -f $file ];then

coding=$(file -b $file | cut -d ' ' -f1)

   #进行转码
   if [ "$coding" = "ISO-8859" ];then
    local tmpfile=$(mktemp)
    Fright=$(stat -c %a $file)
    Fuser=$(stat -c %U $file)
    Fgro=$(stat -c %G $file)
    iconv -f $scode -t $dcode $file > $tmpfile || Usage
    mv $tmpfile $file &&
    chmod $Fright $file
    chown $Fuser:$Fgrp $file
   fi
  fi
done
printf "      done\n"
}

function u2g()
{
local dir=$1
printf "Convering $dir ......"
for file in $(ls $dir)
do
file="$dir/$file"
if [ -f $file ];then

coding=$(file -b $file |cut -d ' ' -f1)

   #进行转码
   if [ "$coding" = "UTF-8" ];then
    local tmpfile=$(mktemp)
    Fright=$(stat -c %a $file)
    Fuser=$(stat -c %U $file)
    Fgro=$(stat -c %G $file)
    iconv -f $dcode -t $scode $file > $tmpfile || Usage
    mv $tmpfile $file &&
    chmod $Fright $file
    chown $Fuser:$Fgrp $file
   fi
  fi
done
printf "      done\n"
}

[ $# -ne 2 ] && Usage

while getopts ug opt
do
case $opt in
  u) echo "Convert gbk coding to utf-8 ...."
  for dir in $(find $2 -type d)
  do
   g2u $dir
  done

  g) echo "Convert utf-8 coding to gbk ...."
  for dir in $(find $2 -type d)
  do
   u2g $dir
  done

  *) Usage
  exit 1

esac
done
