Shell Scripting Tutorial-17 Use Commands In Your Scripts Video Lecture

hello guys my name is mother and welcome
to my channel this is the 17th tutorial
in the series of tutorials on UNIX shell
programming in this tutorial we're gonna
continue our discussion on shell
scripting and we're going to create
another shell script and this one is
probably going to do more than the
previous one that we created and as I
did in the previous tutorial I'm going
to first save this script file because
that will enable text highlighting or
syntax highlighting in my text editor my
editor will know that this is a script
file and I'll save it in my home folder
and I have called it SS 2 because it's
the second file that we made and I'll
put a comment this is my second script
file
there you go
now I mentioned in the previous tutorial
that in ensure scripts you can basically
use all the commands that we have
learned in this course thus far and not
only the commands that we've learned but
a lot more commands and you know the
manner in which you used those commands
is the same as the manner in which you
use the commands individually at the
terminal wherever you have to make
modifications I'll tell you guys but you
know if suppose you want to see the
directories or files in your current
folder then what you can do is just type
in LS in your script file and if you
want the long listing then you can put
the option - L and if suppose you also
want to see the present working
directory then you can put PWD or you
know what maybe we can put PWD before
using LS - err
that would make more sense and in the
end suppose if you just want to see some
fancy text on screen using banner then
you can include banners whether I'll
just type in the end to mark the end of
the script so that's it that's going to
be our second script file I'll save this
one and it's in the home directory and
let me first clear the terminal for you
and
you can see that the file is there it's
called SS - Lord Sh again and cleared
again now execute it using SH as a
steward SH is my file name and when I
press the Enter key there you go the
first sentence in the output is you know
comes from the execution of PWD in my
script file and then from this line
onwards you have the output of LS - L
and then at the end you see the output
from banner and the end is displayed
using hashes the order in which these
commands got executed is the same as the
order in which you specified them in
your script file and that will always be
true and that's it this is all I wanted
to discuss with you guys in this one
thank you so much for watching and in
the next tutorial we're going to prepare
another script file please ignore their
dog and subscribe to my channel and once
again thank you for watching
