Scp exclude files

I don’t think so you can filter or exclude files when using scp command. However, there is a great workaround to exclude files and copy it securely using ssh. This page explains how to filter or excludes files when using scp to copy a directory recursively.

How to use rsync command to exclude files

The syntax is:
rsync -av -e ssh --exclude='*.out' /path/to/source/ user@hostB:/path/to/dest/
Where,

1. -a : Recurse into directories i.e. copy all files and subdirectories. Also, turn on archive mode and all other options (-rlptgoD)
2. -v : Verbose output
3. -e ssh : Use ssh for remote shell so everything gets encrypted
4. --exclude='*.out' : exclude files matching PATTERN e.g. *.out or *.c and so on.

Example of rsync command

In this example copy all file recursively from ~/virt/ directory but exclude all *.new files:
$ rsync -av -e ssh --exclude='*.new' ~/virt/ root@centos7:/tmp
Sample outputs:

centos71.log  centos71.qcow2  centos71.qcow2.new  centos71.v2.qcow2.new meta-data  user-data

Copy everything in the current directory except .new file(s):
$ shopt -s extglob
$ scp !(*.new) root@centos7:/tmp/
Sample outputs:

centos71.log                                  100% 4262     1.3MB/s   00:00    
centos71.qcow2                                100%  836MB  32.7MB/s   00:25    
meta-data                                     100%   47    18.5KB/s   00:00    
user-data                                     100% 1543   569.7KB/s   00:00

Understanding extglob shell option to exclude files with scp and rsync

If the extglob bash shell option is enabled using the shopt command (builtin), several extended pattern matching operators are recognized by the Linux system as follows:
