Name

chgrp - change group ownership

chgrp [OPTION]... GROUP FILE...
chgrp [OPTION]... --reference=RFILE FILE...

Examples

Lets create directories in /tmp to test chgrp command. 

# cd /tmp
# mkdir -p directory1/directory2

also we can create file in /tmp/directory1/directory2 

# touch /tmp/directory1/directory2/file
# ls -ld /tmp/directory1/directory2/
# ls -l directory1/directory2/

At this stage as we can see the group ownership is assigned to root for both directories and file. To change ownership of directory1 to linuxconfig we can enter command: 

# chgrp linuxconfig /tmp/directory1/
# ls -ld /tmp/directory1/
# ls -ld /tmp/directory1/directory2/

The group ownership of directory1 has been changed to linuxconfig. To change group ownership of directory2 and file within directory2 we can use recursive options -R. 

# chgrp -R linuxconfig /tmp/directory1/
# ls -ld /tmp/directory1/
# ls -ld /tmp/directory1/directory2/
# ls -l /tmp/directory1/directory2/
