SFTP bash shell script to copy the file from source to destination
提问by Ashish Sood
I have created one script to copy the local files to the remote folder, the script is working fine outside of if condition but when I enclosed inside the if condition the put command is not working and logged into the remote server using sftp protocol and when exist it's showing the error: put command not found
我创建了一个脚本来将本地文件复制到远程文件夹，该脚本在 if 条件之外工作正常，但是当我将 if 条件括起来时，put 命令不起作用并使用 sftp 协议登录到远程服务器，当存在时它显示错误：未找到放置命令
see what is happening after executing the script

sftp.sh: line 23: put: command not found
Please find the below script.
请找到以下脚本。
echo -e;
echo -e "This script is used to copy the files";
sleep 2;
localpath=/home/localpath/sftp
remotepath=/home/destination/sftp/
if [ -d $localpath ]
then
echo -e "Source Path found"
echo -e "Reading source path"
echo -e "Uploading the files"
sleep 2;
sftp [email protected]
put $localpath/* $remotepath
else

In a simple case such as this, you could use scpinstad of sftpand specify the files to copy on the command line:
在像这样的简单情况下，您可以使用scpinstad ofsftp并在命令行上指定要复制的文件：
scp $localpath/* [email protected]:/$remotepath/
But if you would rather want to issue sftp commands, then sftp can read commands from its stdin, so you can do:
但是，如果您更愿意发出 sftp 命令，那么 sftp 可以从其标准输入读取命令，因此您可以执行以下操作：
echo "put $localpath/* $remotepath" | sftp [email protected]
Or you can use a here documentto pass data as stdin to sftp, which might be easier if you want to run several sftp commands:
或者，您可以使用here 文档将数据作为 stdin 传递到 sftp，如果您想运行多个 sftp 命令，这可能会更容易：
sftp [email protected] << EOF
put $localpath/fileA $remotepath/
put $localpath/fileB $remotepath/
EOF
Finally, you could place the sftp commands in a separate file, say sftp_commands.txt, and have sftp execute those commands using its -bflag:
最后，您可以将 sftp 命令放在一个单独的文件中，例如sftp_commands.txt，并让 sftp 使用其-b标志执行这些命令：
sftp -b ./sftp_commands.txt [email protected]
