This article is about how to recursively exclude files when using the scp command. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Q: I need to copy all the folders that contain * .c files from my local notebook named hostA to hostB. I use the following scp command, but I don't know how to exclude specific files (such as * .out):

$scp-r ~ / projects/ user@hostB:/home/delta/projects/

How do I tell the scp command to exclude specific files or directories from the Linux/Unix command line?

People can use the scp command to securely copy files between network hosts. It uses ssh for data transfer and authentication. The 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 you can filter or exclude files when using the scp command. However, there is a good solution to exclude the file and copy it securely using ssh. This page explains how to filter or exclude files when using scp to recursively copy directories.

How to use the rsync command to exclude files

The syntax is:

Rsync av-e ssh-- exclude='*.out' / path/to/source/ user@hostB:/path/to/dest/

Here:

-a: recursively to the directory, that is, copy all files and subdirectories. In addition, turn on archive mode and all other options (equivalent to-rlptgoD)

-v: detailed output

-e ssh: use ssh as the remote shell so that everything is encrypted

-- exclude='*.out': excludes files that match patterns, such as * .out or * .c.

Example of the rsync command

In this example, all files are copied recursively from the ~ / virt/ directory, but all * .new files are excluded:

$rsync-av-e ssh-- exclude='*.new' ~ / virt/ root@centos7:/tmp

Sample output:

Scp exclude files but using rsync exclude command

If rsync is not found on the remote server, the rsync command will fail. In this case, try the following scp command, which uses bash shell pattern matching in the current directory (it cannot be used with the-r option):

$ls

Sample output:

Centos71.log centos71.qcow2 centos71.qcow2.new centos71.v2.qcow2.new meta-data user-data

Copy everything in the current directory except .new:

$shopt-s extglob$ scp! (* .new) root@centos7:/tmp/

Sample output:

Centos71.log 100% 4262 1.3MB/s 00:00centos71.qcow2 100% 836MB 32.7MB/s 00: 25 meta-data 100% 47 18.5KB/s 00:00user-data 100% 1543 569.7KB/s 00:00
