经典FTP Shell脚本一例

发布时间：2014-11-17 编辑：jiaochengji.com

分享一个经典的ftp shell脚本，实现文件的ftp本地、远程服务器的互转，有需要的朋友参考下。

以下shell脚本，实现ftp文件操作：本地到远程服务器，以及远程到本地的文件传输。

代码：

复制代码代码示例:

#!/usr/bin/ksh
# Program        : ftp_script.sh
#     # Functions      : get_job_num,
#     check_ftp_log,
#                  send_notify,
#                  build_ftp_script,
#                  backup_data,
#                  run_ftp_script,
#                  log_err_msg   # Child Scripts : None
# Change History :

get_job_num()
{
#   Build the job number to fetch details from TABLE
    NUM=$1
    LEN=${#NUM}
    case $LEN in
        1) JOB_NAME=xyz000${NUM};;
        2) JOB_NAME=xyz00${NUM};;
        3) JOB_NAME=xyz0${NUM};;
        4) JOB_NAME=xyz${NUM};;
    esac
    return
}
