函数库中的部门代码
远程执行命令，传送文件，或者文件同步。自动输入密码。需要expect的支持。
常在linux下操作的话，这些肯定是容易用到的。绿色的。不用使用rexec和rsync。
更方便。存入文件，source 一下即可。

用法
登陆  se ip/主机名
gexec ip/主机名  ip/主机名  'cmd'
gsyn ip/主机名  ip/主机名  文件或者目录的位置

#ssh login or execute comd
se()
{
    [[ -z $1 ]]&& echo se se3 who
    [[ "$1" > = ]]&&host=$1.xxxxx.com||host=119.42.239.$1
    ssh $host $2

}

#execute cmd in group, example, gexec se2 se3 35 'ps -x'
gexec()
{
    for i in ${*:1:$#-1};
    do
        [[ $i > = ]]&&host=$i.xxxxx.com||host=119.42.239.$i
        ex ssh $host ${*:$#}
    done
}

#distribute directorys or files, example, gsyn se2 se3 35 ~/dir
gsyn()
{
    cd `dirname ${*:$#}`
    cd $OLDPWD
    for i in ${*:1:$#-1};
    do
        [[ $i > = ]]&&host=$i.xxxxx.com||host=119.42.239.$i
        ex scp -r ${*:$#} $host:$OLDPWD/
    done
}

gscp()
{
    for i in ${*:1:$#-2};
    do
        [[ $i > = ]]&&host=$i.xxxxx.com||host=119.42.239.$i
        ex scp -r ${*:$#-1:1} $host:~/${*:$#}
    done
}

check()
{
    if [ $# = 0 ]
    then
        echo "check ip|file|config string"
        return
    fi
    case $* in
        file)
        find . -name "*.*" | xargs grep /home/.* | awk -F/home '{print $1":/home"$2}'| sed -e 's/[^a-zA-Z0-9]*$//'|awk -F: '{gsub("\""," ");system("if [ ! -e  "$3" ] ;then echo \""$0"\" ;fi;")}'
        echo "WARNNING, those files wasn't exist,please check "
        ;;
        ip)
        find . -name "*.*" |xargs grep "[1-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}"
        ;;
        *)
        ls|xargs grep "$1"
        temp=`ls|xargs grep "$1"|sed -n $3p|uniq`
        if [[ -n $2 ]]
        then
            temp=`echo $temp|awk -F= '{print $2}'`
            [[ $temp = "$2" ]]&&print OK||print WARNNING
        fi
        ;;
    esac
}
