Bash scp several files password issue
提问by Matt
I am trying to copy several files from a remote server into local drive in Bash using scp. Here's the part of the code
我正在尝试使用 scp 将多个文件从远程服务器复制到 Bash 中的本地驱动器。这是代码的一部分
scp -r -q $USR@$IP:/home/file1.txt $PWD
scp -r -q $USR@$IP:/home/file2.txt $PWD
scp -r -q $USR@$IP:/root/file3.txt $PWD
However, the problem is that EVERY time that it wants to copy a file, it keeps asking for the password of the server, which is the same. I want it to ask only once and then copy all my files.
但是，问题是每次要复制文件时，它都会不断询问服务器的密码，这是相同的。我希望它只询问一次，然后复制我的所有文件。
And please, do not suggest rsync nor making a key authentication file since I do not want to do that. Are there any other ways...? Any help would be appreciated
并且请不要建议 rsync 或制作密钥身份验证文件，因为我不想这样做。有没有其他办法……？任何帮助，将不胜感激

You can use expectscript or sshpass
您可以使用expect脚本或sshpass
sshpass -p 'password' scp ...
sshpass -p 'password' scp ...
#!/usr/bin/expect -f
spawn scp ...
expect "password:"
send "ur_password"
An disadvantage is that your password is now in plaintext
一个缺点是你的密码现在是明文

I'm assuming that if you can scp files from the remote server, you can also ssh in and create a tarball of the remote files.
我假设如果你可以从远程服务器 scp 文件，你也可以 ssh 并创建远程文件的 tarball。
The -r flag is recursive, for copying entire directories but your listing distinct files in your command, so -r becomes superfluous.
-r 标志是递归的，用于复制整个目录但在命令中列出不同的文件，因此 -r 变得多余。
Try this from the bash shell on the remote system:
从远程系统上的 bash shell 试试这个：
$ mkdir /home/file_mover
$ cp /home/file1.txt /home/file_mover/
$ cp /home/file2.txt /home/file_mover/
$ cp /root/file3.txt /home/file_mover/
$ tar -cvf /home/myTarball.tar /home/file_mover/
$ scp -q $USR@$IP:/home/myTarball.tar $PWD

Well, in this particular case, you can write...
好吧，在这种特殊情况下，您可以编写...
scp -q $USR@$IP:/home/file[1-3].txt $PWD
