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,
- -a : Recurse into directories i.e. copy all files and subdirectories. Also, turn on archive mode and all other options (-rlptgoD)
- -v : Verbose output
- -e ssh : Use ssh for remote shell so everything gets encrypted
- --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:
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 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]
