Command of the Day: chown

As with chmod, this is another program that has stood the test of time…Unix time ba dum tsh. This was also another command that was released with Unix 1, and the GNU version was released as part of Fileutils in October 1992. The chown command stand for change owner. As you may have guessed, it allows one to change the owner of a file or directory, and allows you to change the group as well.
/usr/bin/cat ⏎ 

Command of the Day: chmod

This is one of the oldest commands as it has been around since the first version of Unix that was released in 1971. The GNU version was written by David MacKenzie, the same author as head, tail, and many others that I haven’t covered yet. chmod stands for change mode. What some may consider to be file permissions were considered modes, and are still referenced as such.
/usr/bin/cat ⏎ 

Command of the Day: top

Like all great Unix commands, top has a meaning behind its name. It stands for Table Of Processes. Not surprising as it shows a wealth of information running about the system. If you’re running a Linux machine, or macOS (or some BSD variant), top is an extremely useful program. It is a task manager, err..well, more of a system monitor, but has some task manager like properties. The original program was first released in 1984 by William LeFebvre for Unix.
/usr/bin/cat ⏎
