BASH：如何通过ftp传递文件名变量

Question

I am trying to upload multiple files to a remote server via FTP.

The file names have been extracted into a variable and are separated by a single space, example:

testVideo.mp4 testVideo2.mp4

How can I get these file names to be used by 'put' or 'mput' for example to transfer the files themselves to the remove server?

This works:

var="testVideo.mp4 testVideo2.mp4"
mput $var

Much obliged for any help.

Answer 1

Using a string to hold the list of file names is fundamentally flawed, since a filename could contain a space. (Does var="foo bar.mp4 baz.mp4" contain two or three filename?) Instead, use an array:

var=( "testVideo 1.mp4" "testVideo 2.mp4" )
mput "${var[@]}"

The quoted expansion of the array guarantees that if any element of the array itself contains whitespace, that element will be properly quoted as a single argument to mput .

Answer 2

ncftpput can accept a list of local filenames, and ftp them to a remote host. See http://www.ncftp.com/ncftp/doc/ncftpput.html
