使用 SFTP 附加日期时重命名文件

Question

我正在使用 sftp 将文件从 az/OS 系统发送到 Linux ftp 服务器。

一旦文件驻留在 Linux 机器上，我想将日期附加到文件名中。 （例如：filename.txt 变为 filename122308.txt）

我尝试使用“date +%m%d%y”执行“重命名”命令 - 文件已重命名，但标志未执行（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

？

Answer 1

命令通过 JCL 控制卡发送。 我认为这种方法行不通。

Answer 2

由于 sftp 没有运行 shell，因此无法执行 date 命令。 您可能必须在发送方评估所需的新名称，然后执行 sftp 重命名。

另一种选择是将文件发送到队列区域（例如带有日期字符串的文件夹），并让 Linux 盒子上的脚本相应地移动/重命名接收到的文件。

Answer 3

你可以通过命令行来完成吗？ 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
!

Answer 4

您可以访问 Linux 服务器吗？ 在这种情况下，您只需重命名那里的文件即可。 例如，您可以使用 inotify 来监视目录，然后使用一个脚本在该目录中创建新文件时将日期添加到文件中。

这是 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。

#Simulate the user typing out a command by using the "echo" command.  We use

#"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"

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，您可以在发送之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

如果空间很宝贵，请使用 mv 两次而不是 cp & R M。
