運維工作中，遠端上傳或下載檔案很常用，我分享下我經常使用的sftp指令碼

#!/bin/bash

SCRIPT_NAME=`basename $0`
CURRENT_DIR=$(cd "$(dirname "$0")";pwd)

execute_sftp_cmd()
{
    local host_ip=$1
    local user_name=$2
    local user_password=$3
    local file_name=$4
    local file_dir=$5
    local cmd=$6
 
    local log_file=${CURRENT_DIR}
 
/execute_sftp_cmd.log
    # 如果密碼中包含$符號，需要轉義以下
    user_password=`echo ${user_password} | sed 's/\\$/\\\\$/g'`

    /usr/bin/expect <<EOF > ${log_file}
    set timeout -1
    spawn sftp ${user_name}@${host_ip}:${file_dir}
    expect {
        "(yes/no)?"
        {
            send "yes\n"
            expect
 
 "*password:" { send "${user_password}\n"}
        }
        "*assword:"
        {
            send "${user_password}\n"
        }
    }
    expect "Changing to:*"
    send "${cmd} ${file_name}\n"
    expect "100%"
    send "exit\n"
    expect eof
EOF
   cat ${log_file} | grep -iE "denied|error|failed"
 
 >/dev/null
   if [ $? -eq 0 ];then
        echo "Script execute failed!"
        return 1
   fi
   return 0
}
execute_sftp_cmd "[email protected]"

舉一個下載檔案的例子，上傳檔案也是支援的
