Git Tutorial - 9 - Comparing the Staging Area with the Repository Video Lecture | Version Control with Git - IT & Software

what's up guys bucky here and welcome to
your ninth get tutorial and in this
video i want to talk to you guys a
little more about diff and i want to
show you guys a problem that a lot of
beginners have and i want to explain it
and hopefully after this video you'll
understand on how to avoid this problem
so let's just go ahead and open up any
text file i'm just hold on got a
freaking itch in my eye
mmm oh it's stuck to my eyeball awesome
so uh let's just go ahead and make some
changes to the first text file and i
just put like hand blasts or whatever so
let's go ahead and save this and now if
you open up bash and put get diff it
says okay that file which is the one on
your working copy is different from the
one in the repository so that's why it
pretty much is telling you the changes
that's what we learned in the last video
right but check this out what I'm gonna
do now is put git add first text and
whenever I hit enter what it does is it
takes this file and takes it and takes
it from the working copy and puts it in
the staging area so if I do get this now
and hit enter a lot of people expect to
see the differences but what this diff
command does is it only shows the
differences between your working copy in
the repository since this file is now in
the staging area it's not comparing it
against the repository so that's why it
looks like everything is up-to-date even
though you still have this file that's
different than the one in your
repository so if you're like okay I open
up my gift bashing so how exactly do we
compare the staging area against the
repository well it's actually really
really easy put git diff and again what
this is doing is comparing your
repository against your working copy but
if you add the option - -
staged and to enter what this does now
is it compares the files in your staging
area against the repository so remember
just real quick get def compares working
copy in a repository and get this stage
compares staging area in a repository so
now what we can do let's just go ahead
and get come in and we'll just put a I
don't know made some really dumb changes
hit enter and now if we do get status
enhancer our working directory scaling
again so I just want to point out that
difference well shows a difference the
that detail about the difficulty of so
thing guys for watching don't forget
subscribe and I'll see you guys next
time
