Raspberry Pi Linux LESSON 9: Using the Linux Sort Command

This is a quick lesson that shows you how to sort lists and files using the Linux sort command. We show how you can sort a file with output going to your terminal window, or how to send the output to a new file. We look at sorting alphabetically, numerically or by calendar month. We also show how to reverse sort.

See more details on this lesson at our WEB site at:

Thanks a lot for all your lessons, i really learn from your vids. I just want to add (as i learned now on my own) that the sort -M command only works when you type in the months in the same language as the raspberry is setup with the language/country settings :-).

nice tut. also iv used a command called alias and i use it for all kinds of things but 1 good reason to use it is if your used to windows commands and you miss dir command you can alias ls and dir together and now when i type dir it actually ls :)
here are some examples you can use for a future lesson if you wish to!

here is an example which will allow ipconfif to be used instead of just ifconfig on linux when your used to windows this can be quite fun

type in your terminal the following:

alias ipconfig='ifconfig'

heres that dir example:

alias dir='ls -l'

Heres a ssh connect line example:


another eample for resetting a service:


alias srest='sudo /etc/init.d/apache2 restart'
heres an example for ssh connection to a raspberry pi

alias picon1='ssh 192.168.1.16'

(please note that the above example about ssh is not permanent but the rest are! can you work out how to make this a permanent alias?

Paul-

Excellent class. I find myself trying to find examples in which to implement these commands. More to follow...

Great video Mr. Mcwhorter. I didn't know any of these commands thank you.

A new command "touch" was used here but never explained on previous lessons.
If someone wants to know, I found this: The touch command is used to create, change and modify timestamps of a file.

Got a question. I'm not trying to be rude but what is the point of learning this command lines when you can do them in graphic interface (not sure what to call it... Linux?) ? Is it to use them in python codes later on ? or maybe some sort of batch files ? Thanks for the great upload.

Linus Torvalds and everyone else on the planet pronounces it Lih-nix (not Lie-nix). Get it straight!
What did I learn? You can't type, you can't spell July, you forgot October, and you take 40 forevers to teach the simplest Linux commands.
