Shell Scripting Tutorial-6 Rename & Delete Files & Directories Video Lecture

hello guys my name is mother and welcome
to my channel this is the sixth tutorial
in the series of tutorials on UNIX shell
programming in this tutorial we'll be
checking out the MV command which is
used to rename files and directories and
we'll also be learning how to remove or
delete directories through the terminal
using the RM command now what I'm going
to do is I'm going to first create a
file using touch-touch is something that
we learned about two tutorials ago I
don't really remember I recorded it a
few days ago so anyway we type in touch
and then give a space character and then
type in name for our file let's call
this one anything let's call it forest
under sport Gump
right and I can actually see in my home
folder that my father's been created
it's an empty text file and that's what
touched us for you now if suppose I want
to rename this file from forest
underscore come to anything let's say if
I want to be knit rename it to the green
month then I'll be using the MV command
and we I'll give a space type in the
name of my file that I want to remain
renamed which is forest underscore come
and then give another space character
and then type in the new name for my
file which would be the underscore green
underscore month and if I type in enter
here
then I'll see in my home folder I no
longer have my file forrest gump because
it has been renamed to the green month
that is what MV does for you it works
the same for dike trees if I have a
directory called new and if I want to
change it to all then you know I'll
simply have to type in RM space new
space all and press Enter and my
directory will be renamed the next thing
that we're gonna check out is how to
remove files or directories using the RM
command now if suppose I want to remove
my file the green month the command T
uses RM I'll type in RM give a space and
then type in the name of my file
which is the underscore green underscore
mile if I press Enter key
I see that my file is no longer there
right so it has been deleted now what
I'm gonna do is I'm gonna first create a
diet free using mkdir and i'll call it
new press and enter and i see in my home
folder that I have my directory right
here
now I'll try to remove the static
reusing RM RM space new that's how it
should be because you know that's how we
did it for the files so you know let's
try to repeat it for a diet free but you
get an error message system it says that
RM cannot remove new because it is a
directory but then RM is capable of
removing directories you just have to
provide it an option so that it knows
that what it's trying to remove is a
diet tree and it you know it's it's it's
sort of like commanding a command to
just obey the orders and you know not
think about the consequences so we have
to type in RM and then - R is the option
and I just typed in RM first gave a
space and then type in - R and another
space and this time if I type in my diet
free name and press Enter I don't get
any error message and I can see in my
home folder sorry that my new folder is
not there now another thing that you can
do if you do not want to use RM with the
hyphen R option to remove diet trees is
let me first create one and give you our
test type in enter I see that I have a
test folder in my home folder if I want
to delete it without using RM I can use
a command called rmdir it's a substitute
for RM - R and if I type in the name of
my directory which in this case is test
that's what I'm going to remove and
press Enter
I can see that in my home folder test no
longer exists so that's it for this
tutorial
these are the two commands that I wanted
to discuss with you guys and in the next
tutorial we learn how to cop
files using CP and also how to create
links both kinds of links soft links as
well as hard links so stick with me I
