shell脚本gbk环境下搜索utf-8日志

方法1：

使用linux iconv将utf-8日志转为gbk编码的文件，然后gbk环境下统计数据。

utf8(){
    LOG_FILE="/lcims/crontab_shell/outfile/lan_wlan_wo/SocketMain.log141114_lan1"
    LOG_FILE_TMP="/lcims/crontab_shell/outfile/lan_wlan_wo/141114_lan1"
    echo "utf-8-----"

    #only linux os use iconv
    iconv -f utf-8 -t gb2312 $LOG_FILE >$LOG_FILE_TMP
    echo "--------result"

    more $LOG_FILE_TMP|  grep "接收"|head -4;
}

gbk(){
    echo "gbk----"
    LOG_FILE="/lcims/crontab_shell/outfile/lan_wlan_wo/SocketMain.log141114_wlan2"
    LANG=zh_CN.gb18030;export LANG;
    more $LOG_FILE|  grep "接收"|head -4;
}

utf8
gbk

方法2：

在gbk环境下，通过将gbk中文字符串转为utf-8字符串，然后通过utf-8字符串去搜索utf-8的日志文件。

utf8(){
    LANG=zh_CN.utf8;export LANG;
    LOG_FILE="/lcims/crontab_shell/outfile/lan_wlan_wo/SocketMain.log141114_lan1"
    LOG_FILE_TMP="/lcims/crontab_shell/outfile/lan_wlan_wo/141114_lan1"
    echo "utf-8-----"

    more $LOG_FILE|  grep `perl -e 'use Encode;$a=encode("utf-8",decode("gb2312","接收"));print  $a'`|head -4;
}

utf8
