I run the command
cp -r <Folder Name> .<Folder Name>. It have done something, but I cannot find it.
cp -r Agent .Agent.old # (There is a dot symbol on the 2nd folder name)
Prefixing the file name with a dot (
.) is usually considered as hidden files. This folder copying should have done in the same way.
try to list hidden items by.
ls -la .Agent.old
