You are awesome, dude! I hope I get good enough one day to be able to post helpful vids like this. :D Quick question about Ubuntu Desktop... oh, nvm, I'll just utilize some of tips you shared in this vid to find the answer my own damn self ;)
Hey Dave, I have been watching your videos a lot recently as I really enjoy them and appreciate what you are doing .. keep it up :) I have a request which may sound silly or kinda "stupid", but I was wondering if you can create a video simulating the day-to-day activities of a system admin (Linux CLI of course cause I do not believe it is real administration otherwise :) ) .... I have basic system admin experience and passed the LFCS recently, and I had installed and handled several servers in the past 5 years (mainly a few Cacti NMSs) and I never felt like I did any admin work...like in the whole 5 years only last year one server showed some performance issues and I used top to notice the average load and then ended up having IT ( I am an RF engineer but I handle this stuff as our IT only know "Monopolisoft" lol) add more vCPUs as they were needed in addition to adjusting the poller threads/proccesses. so I want to become a system admin but in all honesty I have no idea what to expect...is it just basic stuff like user creation and partitioning...etc ...what LFCS or RHCSA covers? I appreciate if you can answer this request or actually make a video as I failed to find one ( perhaps you have one which I didnt find?). Also, anyone you know needs an excited linuxer willing to do work in exchange for the most expensive rate possible...not money..but mentoring :) ? I am more than willing to work (on my free time) for free for the right mentor. Regards, Ahmad
hello tutorialLinux i have one question if u can help me im using linux fedora i dono much about linux just simple stuff and commands and how to run it, but couple of days back i wanted to open my system but it gave me "Minimal Bash-like line editing is supported. For the first word, TAB lists the possible command completions. anywhere else TAB lists possible device or file completions." im running dual linux and win 10 i started win 10 using f12 it works fine but Fedore doesn't. got any ideas? Thanks
You're seeing the Grub bootloader console, as Grub was unsuccessful booting into your Linux kernel. Dave may have a video on this at a later date, since it can come up in the RHCSA objectives.
awk/mawk/gawk/nawk: awk certainly is a great little language, altho back in the 90's we really thought Perl 5 obsoleted it by bringing together sed, awk, egrep, shell functionality and a lot more together in one neat package. It is weird to see how much it has stayed around whereas a lot of people treat Perl 5 as dead despite new versions coming with all distros constantly...I guess people either dislike the syntax or...something. On the very recent Ubuntu distro I'm looking at, (admittedly thru WSL as I am on my Win 10 box right now, but I don't think that changes things at all) it looks like you'd only get mawk by calling it explictly: MyPrompt $ ls -l /usr/bin/*awk* lrwxrwxrwx 1 root root 21 Jul 25 11:50 /usr/bin/awk -> /etc/alternatives/awk -rwxr-xr-x 1 root root 658072 Feb 11 2018 /usr/bin/gawk -rwxr-xr-x 1 root root 3189 Feb 11 2018 /usr/bin/igawk -rwxr-xr-x 1 root root 125416 Apr 3 2018 /usr/bin/mawk lrwxrwxrwx 1 root root 22 Jul 25 11:50 /usr/bin/nawk -> /etc/alternatives/nawk MyPrompt $ ls -l /etc/alternatives/*awk* lrwxrwxrwx 1 root root 13 Jul 25 11:53 /etc/alternatives/awk -> /usr/bin/gawk lrwxrwxrwx 1 root root 29 Jul 25 11:53 /etc/alternatives/awk.1.gz -> /usr/share/man/man1/gawk.1.gz lrwxrwxrwx 1 root root 13 Jul 25 11:53 /etc/alternatives/nawk -> /usr/bin/gawk Confirmed by --version: MyPrompt $ awk --version GNU Awk 4.1.4, API: 1.1 (GNU MPFR 4.0.1, GNU MP 6.1.2) Copyright (C) 1989, 1991-2016 Free Software Foundation.

A minor point compared to whether one prefers perl or bash/gawk, but apropos to the video, you want to make sure the man page, info, etc. you are reading corresponds to the version you are actually calling, right?

Dude tldp's bash guide is amazing and exactly what I was looking for!

today I played your bash programming tutorial, I fall asleep at end of first video and woke up on seventh one....now, I gotta watch them again.
Yeah, that's bad news for my bash tutorials. I wish they were a bit more exciting :-). But sometimes, you just gotta learn some stuff.

It's ok man.
Some people voice make sleep too .
Like DarkViperAU.
Thx. from a future sysadmin :)

I have visions of you sat in your corner at work giggling away just typing 'man man' on the command line :P
Very useful :)
