I would like to know how can I show the content of multiple folders into one folder on linux.
For an Exemple :
I have the dir "/home/username/folder1" with 2 files in it "file1 and file2"
and I have the dir "/home/username/folder2" with 4 files in it "file10,file11,file12,file13"
what I want is to show "file1" and "file2" into "folder2", I don't want to show the directory "folder1" with ln -s.
