+How to exclude file when using scp command recursively
+======
+
+I need to copy all the *.c files from local laptop named hostA to hostB including all directories. I am using the following scp command but do not know how to exclude specific files (such as *.out):
+```
+$ scp -r ~/projects/ user@hostB:/home/delta/projects/
+```
+
+How do I tell scp command to exclude particular file or directory at the Linux/Unix command line?
+
+One can use scp command to securely copy files between hosts on a network. It uses ssh for data transfer and authentication purpose. Typical syntax is:
+
+```
+scp file1 user@host:/path/to/dest/
+scp -r /path/to/source/ user@host:/path/to/dest/ 
+```
+
+## 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/ [[email protected]][1]:/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/ [[email protected]][1]:/tmp`
+Sample outputs:
+[![Scp exclude files but using rsync exclude command][2]][2]
+
+Rsync command will fail if rsync not found on the remote server. In that case try the following scp command that uses [bash shell pattern matching][3] in the current directory (it won't work with the -r option):
+`$ ls `
+Sample outputs:
+```
+centos71.log centos71.qcow2 centos71.qcow2.new centos71.v2.qcow2.new meta-data user-data
+```
+
+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)* [[email protected]][1]:/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
+```
+
+
+See the following man pages for more info:
+```
+$ [man rsync][4]
+$ man bash
+$ [man scp][5]
+```
