Use the 'cp' command in a Bash script and exclude a specific directory

Question

I need to run this command in a shell script to copy source > destination and exclude a folder.

No rsync, tar, find, mv, etc.

Exactly this command:

cp -var test/!(test2) testbkp

1. In the shell it works
2. Run from a Bash script without exclude like cp -var test testbkp it works.

When I try to run from a Bash script with the exclude option

cp -var test/!(test2) testbkp, it doesn't work.

There isn't any output, nothing, and no error message.

I checked this post too, but no result: cp command won't run if executed from shell script

How can I run this cp command in a Bash script and exclude folders?

Answer 1

You should enable the extglob option, it isn't enabled by default in scripts:

#!/bin/bash
shopt -s extglob
cp -var test/!(test2) testbkp

Also verify that the script is indeed running under bash.
