How to change file or directory owner in Linux

Each file or directory in Linux has an owner, group, and permissions that allow who can read, write, and execute the file.

If you wish to change the owner for a file or directory, you can make use of the chown command. Using the chown command you can change both the owner user and the owner group for a file or directory.

sudo chown <new-user-name>:<new-user-group> file/directory

Example 1 : Change owner only

File:

sudo chown code2care /Users/c2ctech/data/data.csv

Directory:

sudo chown code2care /Users/c2ctech/data

Example 2: Change owner group only

File:

sudo chown :devs /Users/c2ctech/data/data.csv

Directory:

sudo chown :devs /Users/c2ctech/data

Example 3: Change both owner and group

File:

sudo chown code2care:devs /Users/c2ctech/data/data.csv

Directory:

sudo chown code2care:devs /Users/c2ctech/data
