BASH Scripting in Linux Lesson 1 - create, execute and debug scripts

[@kevinthomas1489]

Great introduction to bash Andrew.

The colors inside vim (or vi) are difficult to read. Change colors or at least disable the colors option.

[@rainonmyface]

I came here to say this - super great tutorial, it is a little difficult to see when it goes to blue on black.

[@farahmohumad5355]

nano is the best

[@farahmohumad5355]

i like it the way you explain if

[@DoodahGurl]

Great video. Very informative! Thanks for uploading.

[@drakejohnson3803]

I don't know if you still look at these comments, but I had a few questions. First, is there a way to put if statements on one line? Second, why do you use "vi" instead of "nano" for text editing? I saw someone else use nano and a different person use vi. Is there somereason I should use vi over nano?

[@theurbanpenguin]

+Drake Johnson Sure: cd /etc ; ls This will first change to the /etc directory and then list it. There is no conditional logic here. In other words the 2nd command will always try to tun even if the first command fails cd /etc && ls Here the listing with ls only runs cif the first command succeds. So we know we are listing the /etc directory cd /test || mkdir test In this last example the second command only runs if the first command fails. In this case we create the directory if it does not already exist. All of these examples can include more than two commands. In the long run you can do more with vi or vim than you can with nano. Nano is great wheile you are learning but try vi as well

***** Thanks a lot. But by if statements on one line I meant could you do: if [[ $USER = "$USER"]] then echo "Your username for this computer is $USER." fi Instead of: if [[$USER = "$USER"]] then echo "Your username for this computer is $USER." fi

[@neckbont]

Thanks for the video very however where do you define what the variable USER is in the script?

[@theurbanpenguin]

The variable $USER is set during the login and is part of your environment. As such you so not need to set the USER variable

[@TraceguyRune]

+kornsnap $USER is a constant and a global. It's defined by the system

[@ScreenPrintR]

Mr. The Urban Penquin, do you have an online site with courses? Thank you in advance. Oops, I found it. Sorry. Must have misspelled it before.

[@m-stermoh803]

[@devilsey3]

Well video,,good for basic concept :)

[@add111ful]

too gud nice explanation...

[@CosminRusu154]

VERY NICE!!!

[@joshoduyoye110]

SO when you set USER to andrew... are assigning andrew to the user or are you using typing andrew when you execute it?

[@jzantana]

+Josh Oduyoye That's an environment variable that gets its value upon login.

[@taurus151986]

[@theurbanpenguin]

[@taurus151986]

+theurbanpenguin thanks a lot

[@TraceguyRune]

+Albert Rama make sure its in one of the $PATH directories try this: mv bash01.sh $HOME/bin/

[@paasaanepali8729]

where did you get that if section from

[@stablizershock]

I want to execute command in current folder without defining patch how to do it>?

[@theurbanpenguin]

+stablizershock ./ or bash

[@stablizershock]

***** I made sh file named as "install.sh" and i use "sh install.sh to execute but I want my customers to just open the file and command run as intended so should I use "./install.sh" command?

[@brianmcgrady2674]

when I echo $PATH I dont have a /home/bri/bin , any isea why?

[@theurbanpenguin]

+Brian Mcgrady you can add it to your path variable PATH="$PATH:$HOME/bin"

[@changjoe01]

Thank you !

[@DJReeRee]

Relax, Kris. This is a learning environment for us all. Its not stupid about the comment i made as mary clo. I am at work and we have virtual box on our machines, we do technical support and you tube videos play extremely lower for us than that of windows. i was only commenting from my personal experience. No need to be insulting.

[@theurbanpenguin]

Nu, but speak a little. I have friends in Cluj and we visit at least every year

[@RenegadeFury]

that's sorta annoying how it's not == compared to most languages when checking

[@TraceguyRune]

+Barack Lasagna Actually, its about half and half. Half the languages out there don't require "=="

[@koczewniknawsegda3656]
