To use rsync to copy files and directories with whitespace or blank characters in their names, you will need to enclose the names in quotes or use the -- option to indicate the end of options.
Here's an example of how to use rsync to copy a file with a whitespace character in its name:
rsync "file name.txt" user@remote:/destination/
This will copy the file file name.txt from the current directory to the /destination/ directory on the remote host.
Alternatively, you can use the -- option to indicate the end of options and avoid the need to enclose the file name in quotes:
rsync -- file\ name.txt user@remote:/destination/
You can use a similar approach to use rsync to copy a directory with a whitespace character in its name. For example:
rsync -- "directory name/" user@remote:/destination/
This will copy the directory directory name/ from the current directory to the /destination/ directory on the remote host using rsync.
By enclosing the names in quotes or using the -- option, you can use rsync to copy files and directories with whitespace or blank characters in their names. It's always a good idea to carefully review the documentation and use the appropriate options when using rsync. This will help ensure that your files are transferred correctly and that any problems are detected and addressed.
