我正在使用 sftp 从大型机主机向 linux ftp 服务器发送文件。
一旦文件驻留在 linux 机器上，我想将日期附加到文件名。 （例如：filename.txt 变成 filename122308.txt）
我已经尝试使用 'date +%m%d%y' 的 'rename' 命令 - 文件已重命名但未执行标志（文件名变为 filename'date +%m%d%y'.txt
“cp”和“mv”命令不起作用...有什么想法吗？
谢谢。
【问题讨论】：
命令正在通过 JCL 控制卡发送。我认为这种方法行不通。
【讨论】：
由于 sftp 没有运行 shell，所以没有什么可以执行 date 命令。您可能必须在发送方评估您想要的新名称，然后执行 sftp 重命名。
另一种选择是将文件发送到队列区域（例如带有您的日期字符串的文件夹），并在 linux 框上设置一个脚本相应地移动/重命名接收到的文件。

你可以通过命令行来做吗？存在执行 sftp 的选项...
sftp [[user@]host[:file [file]]]
...所以你可以执行...
export WHEN=`date +%m%d%y`
sftp theUser@theHost:filename$WHEN.txt filename.txt <<-!
thePassword
!

您可以访问 Linux 服务器吗？在这种情况下，您可以在那里重命名文件。例如，您可以使用 inotify 来监视目录，然后使用脚本在该目录中创建新文件时将日期添加到文件中。
Here's Python 中的一个简单示例（尽管大多数语言都有 inotify 绑定）。您要监听的事件是 IN_CREATE。

#"put /local/path/file /some/path/fileName09092009.txt"
#That is provided as the command list to sftp because of the single "-" that
#says "get my list of commands from standard-input" The -vvv is for verbose
#(lots of diagnostics) and then the $USERID@$TARGET uses the USERID and TARGET
#variables to connect as user-at-server for the exchange.
#A passwordless SSH authentication is already in place, so no password
#is needed.
echo "put /local/path/file $REMOTEPATH/fileName$WHEN.txt " | \
sftp -b - -vvv $USERID@$TARGET
#Just echo out that we're about to do the next step and change file
#permissions.
echo "Changing file Permissions on REMOTE"
echo "Done"
【讨论】：
不确定您的大型机 SFTP 客户端，但许多 SFTP 客户端支持使用 !运行本地操作系统命令的前缀。因此您可以在发送前将文件复制到新名称，然后发送，然后删除副本。
例如：
!cp filename.txt filename122308.txt
put filename122308.txt
!rm filename122308.txt
exit
如果空间很重要，请使用两次 mv 而不是 cp & rm。
