Changing File Ownership

When UNIX was created back in the 70s, it was strictly developed as multi-user OS. For this reason, files on UNIX had an owner, so that only this owner and the all-mighty root could decide which read, wright and execution rights could be given to the other users on the same system.

Linux and OS X being both UNIX-based operating systems, share this feature. To change the ownership of file, the chown command is used.

chown [user] [file]

For assigning the file to your own username, one can use:

chown $(whoami) [file]
