There are two modifications in Ubuntu that can be used, "change Mode"&"change owner"

That is, chmod and chown, which can use the recursive parameter-r to change permissions for all child files and subdirectories.

1, the use of chmod Modify permissions:

Perform the same permissions changes for all sub-files in the document/directory as subdirectories:

Chmod-r document/

-r parameter is all files and subfolders under the recursive processing directory

700 is a changed permission representation (only the owner has permission to read and write and execute)

document/is the directory that needs to be executed

2. Use Chown to change the owner:
