Shell Scripting Tutorial-12: Sort Video Lecture | Shell Scripting: Discovering to Automate Command-Line Tasks - Back-End Programming

hello guys my name is mother and welcome
to my channel this is the twelfth
tutorial in the series of tutorials on
shell scripting and in this tutorial
we're going to check out the sort
command now sort as the name suggests is
used to sort text now what I'm going to
do in this tutorial is I'm going to
first create two files I'm going to call
the first one animals and I'm just going
to type in some animal names like owls
and camels and pigs and what I was going
to put in here dogs and lions and
elephants and maybe asses yeah and I'll
press control D to end my document there
and I can see my file by typing in cat
animals there you go that's my file and
I'll create another file using cat again
and this one are called sports now just
type in some sport names or cricket and
tennis and what else ice hockey and what
else can I put in here soccer of course
and then basketball and maybe wrestling
yeah I should do it save this file as
well now see a yeah there it is it's
pretty clear my terminal now we get to
our discussion on sort now what sort
does is if I type in sort and if I
provided a file name let's say animals
in what sort would do is it would
extract the text out from animals it
would arrange the sentences in
alphabetical order and it would display
the sorted output on my screen if you
don't believe me then you can see this
Asus comes first and then camels and
then dogs and elephants lions owls and
pigs all these animals have been
arranged enough
but he could order the names that is and
if I would apply sort to sports then I
see that basketball comes first because
it starts with the alphabet B then
cricket because it starts with C and
wrestling because it's got a W as the
first alphabet gets the last position so
that's what sort does for you it's a
pretty handy utility and we can use it
in multiple ways we'll discuss it in
more detail maybe when we get to shell
scripting but I can assure you guys that
you will be using this a lot and the
other thing that you can do with sort is
if you just type in sort and press ENTER
you see that the cursor blinks on next
line and the shell waits for you to type
in some text and what this basically
means is the shell waits for you to type
in input that it can sort and display to
you so let me just type in some film
names or movies on Apocalypse Now
then maybe cast away and the forest come
that's my favorite film right there
then Raging Bull you can forget Scorsese
Oh an aviator
this waters can go in there one more
name huh Saving Private Ryan and when I
press control-d I see that my firm names
are displayed in alphabetical order
Saving Private Ryan was the last entry
that I provided and after that I press
ctrl D and the next statement that
follows is Apocalypse Now which happens
to be the first movie in our list if we
prepare the list in alphabetical order
aviator is the next one then cast away
then Forrest Gump enraging go and Saving
Private Ryan starts with s so it
obviously has to be the last item on the
list so that's it for now that's all I
have to say about sort and there are a
lot of other options that come along
with sword and maybe you can check them
out in your own and maybe if I get a
chance to speak about sword again in
future I'll discuss it but with the time
being thank you so much for watching
this tutorial please subscribe to my
channel and I'll see you in the next one
