使用IBM AIX（UNIX）shell脚本自动执行sftp

问题描述

我试图使用UNIX shell脚本自动执行我的SFTP命令，但出于某种原因，它不起作用。这是我的代码如下。请分享您的想法/见解。

I am trying to automate my SFTP command using a UNIX shell script but for some reason it doesn't work. Here is my code as below. Please share your thoughts/insights.

#This ftp script will copy all the files from source directory into the local directory.
#!/bin/sh
HOST='sftp.xyz.com'
USER='ABC'
PASSWORD='123'
SRC_DIR='From_Src'
TRGT_DIR='/work/'
FILE='abc.txt'

sftp -u ${USER},${PASSWORD} sftp://${HOST} <<EOF
cd $SRC_DIR
lcd $TRGT_DIR
get $FILE
bye

EOF

echo "DONE"

当我尝试执行上面的代码时，出现以下错误。

When I try executing the above code I get the below error.

sftp: illegal option -- u
usage: sftp [-1246Cpqrv] [-B buffer_size] [-b batchfile] [-c cipher]
          [-D sftp_server_path] [-F ssh_config] [-i identity_file] [-l limit]
          [-o ssh_option] [-P port] [-R num_requests] [-S program]
          [-s subsystem | sftp_server] host
       sftp [user@]host[:file ...]
       sftp [user@]host[:dir[/]]
       sftp -b batchfile [user@]host

推荐答案

没有 -u sftp 的选项，请参阅了解可用选项。您可以通过以下格式传递用户名：

There is no -u option for sftp, see the manual for available options. You can pass the username in this format:

sftp username@hostname

所以在你的情况下：

So in your case:

sftp sftp://${USER}@${HOST} <<EOF

这会提示您输入密码。如果您不想提示密码，请查看以下主题：

This will prompt you the password though. If you don't want a password prompt, take a look at this topic: How to run the sftp command with a password from Bash script?
