I remember when I first started as Linux System Administrator, I would google Linux command lines. Expectedly if I was looking for a command but not sure what it might be called. It was not until I came across a command called apropos. It has saved my bacon and time when I was in a bind.

Looking at the command apropos:

In computing, apropos is a command to search the man page files in Unix and Unix-like operating systems. apropos takes its name from the English word with the same spelling that means relevant. It is particularly useful when searching for commands without knowing their exact names. – source: wiki – apropos

basically, this command will search through the manpages in the description and manuals for the command that is being searched. Seeing the command I action:

apropos dmesg

dmesg (1) – print or control the kernel ring buffer
vmcore-dmesg (8) – This is just a placeholder until real man page has been written

 

That’s really cool how a simple the command it. You use the man command to read the manual of the command to go more in-depth with it.

My take on this; I’m glad that I’ve found this command and it has served my well up to the is.
