How to Copy File Permissions and Ownership to Another File in Linux

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.

$ chmod --reference=reference_file file

For example,

$ ls -l users.list
$ ls -l keys.list
$ sudo chmod --reference=users.list keys.list
$ ls -l keys.list

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.

$ chown --reference=reference_file file

For example,

$ ls -l keys.list
$ touch api.list
$ ls -l keys.list
$ sudo chown --reference=keys.list api.list
$ ls -l api.list

You can also copy file permissions and ownership from one file to multiple files as shown.

$ sudo chmod --reference=users.list users1.list users2.list users3.list
$ sudo chown --reference=users.list users1.list users2.list users3.list

For more information, refer to the chown and chmod man pages.

$ man chown
$ man chmod

  1. Thank you for your article.

    May I use the “–reference=” key for folders, not only files?

    For example, to copy permissions or owner on catalog CATALOG1 with all files located in this folder to CATALOG2?

      You are welcome.

      And you can copy the permissions and ownership of CATALOG1 to CATALOG2. Then use the -p flag of the cp command to preserve permissions and ownership while copying files from CATALOG1 to CATALOG2 like this:

      $ chown --reference=CATALOG1 CATALOG2
      $ chmod --reference=CATALOG1 CATALOG2
      $ cp -p ./CATALOG1/* ./CATALOG2/
      

      I hope this makes sense to you.
