Question about using chown recursively

Hi everyone, I’m currently learning Linux and had a question about using the chown -R command. What is the safest way to test ownership changes before applying them to important directories? I want to avoid accidentally changing system files. Any best practices would be appreciated.

 

Create a test directory with some files and practice chown on them.

Code:

mkdir /tmp/TestDir
pushd /tmp/TesDir
touch A
touch B
touch C
ls -lh
