Title: How to Copy File Permissions and Ownership to Another File in Linux
Post by: alext on July 14, 2018, 02:23:59 pm

Assuming you have two files or you have just created a new file and want it to have the same permissions and ownership of an older file.

In this article, we will show you how to copy permissions and ownership from one file to another file in Linux using chmod and chown commands respectively.

Copy File Permissions to Another File

To copy file permissions from one file to another file, use chmod command with the --reference switch in the following syntax, where reference_file is the file from which permissions will be copied rather than specifying mode (i.e octal or numerical mode permissions) for file.

Code: [Select]

$ chmod --reference=reference_file fileFor example,

Code: [Select]

$ ls -l users.list
$ ls -l keys.list
$ sudo chmod --reference=users.list keys.list
$ ls -l keys.list
Copy File Permissions to Another File
Copy File Ownership to Another File

Likewise, to copy ownership from another file, use chown command with the --reference switch as well using the following syntax, where reference_file is file from which owner and group will be copied rather than specifying owner:group values for file.

Code: [Select]

$ chown --reference=reference_file fileFor example,

Code: [Select]

$ ls -l keys.list
$ touch api.list
$ ls -l keys.list
$ sudo chown --reference=keys.list api.list
$ ls -l api.list
Copy File Ownership to Another File
You can also copy file permissions and ownership from one file to multiple files as shown.

Code: [Select]

$ sudo chmod --reference=users.list users1.list users2.list users3.list
$ sudo chown --reference=users.list users1.list users2.list users3.listFor more information, refer to the chown and chmod man pages.

$ man chown
$ man chmod
