Bulk modification of file and folder owners and permissions under Linux

Batch modification of file and folder owners and permissions under Linux requires two commands, chmod and Chown

Example: Perform the same permission change for all files in the/opt/oracle/directory as subdirectories:

Chmod-r 700/opt/oracle/

-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)

/opt/oracle/is the directory that needs to be executed

Example: Perform the same owner change for all files in the/opt/oracle/directory as the subdirectory, so that the owner is modified to the Oracle user of the Oinstall user group

Chown-r oracle:oinstall/opt/oracle/

-R Ibid.

Oracle:oinstall Oinstall User Group of Oracle, user groups do not have to
