Syntax: chgrp <new group> <file/folder>
chgrp is an abbreviation for change group.
With this command you can change the group membership of a certain file or folder.
|chgrp group1 myfile.txt||Change group membership of the file "myfile.txt" to the group "group1".|
Sometimes you might not be able to perform a certain command or task from the Terminal.
This might be because you don't have the right permission to do so.
When that happens you can try to add the word "sudo" in the beginning of the line.
Sudo is an abbreviation of superuser do and means that you want to execute the following command as a user with extended permissions, most often as an Administrator. When using "sudo" you sometimes need to enter the password of the root account.
