Welcome pandatricks. I know you didn't ask for feedback, but I'd like to offer at least one suggestion that should really help your scripting: there is (almost?) never any reason to combine grep and awk. Generally I'd say awk can take care of both steps but in getting your WIFI variable I'm not even sure what awk is doing there: grep only outputs one word, and awk prints the first word of every line. This can be replaced by just grep here - but also note your grep expression is far to specific - it will cut off the end of many wireless interface names. The following would be better:

WIFI=$(ip link | grep -o 'wl[^:]*')

I've also replaced the backticks with $() but that's mostly just a style issue.

There are other cases of excess pipes. The tail -> grep -> awk -> head could definitely be reduced.

Hi there,

Greetings from Jakarta.
I'm Centos 3 and Ubuntu Dapper Drake generation, and i'm stuck with 6.8 Centos and 14.04 Ubuntu for just ignoring SystemD
I like pacman since my childhood, and now i'm starting to use Arch as guest in my win7 vmware. I think i will use it as main host os in my old x220 when i found light and customizable DE for old hardware, later.

Thanks. I'm definitely here to learn, so tips are good.

Also I realised my previous version was crap. I should interrogate the system properties rather than script variables in the reporting lines at the end. I tested the bejeezus out of it today at work and it's much better.

Welcome to the Arch Linux Forum. There are a few DE's suitable for older computers. Guessing that your X220 is a Thinkpad, I doubt you would have trouble running any DE. XFCE4 is pretty light weight (my opinion), and I think LXDE is even lighter. My personal favorite is OpenBox, but it does require you to "get your hands dirty" - set up configuration, menu entries, etc.

I hope you enjoy exploring the Arch Linux world.

Salutations,

I start learning Linux since a couple of weeks, I tried all the fancy distributions, Ubuntu, mint, CentOS etc but I finally landed on arch on learn the depths of Linux. How all the things are working under the hood and arch is quite good at explaining it by making us doing ourselves.

Well I am still trying to install arch again and again to understand mount points, file system tables, network configuration etc.

Best,
aslam

hey been using Arch linux for years. Not really much of a communicator so havent joined the forums. decided what the hell.

phoenix310 · 2017-06-10 19:02:54

Hey all! I'm new to Arch Linux and trying to get my feet wet with it. I've used pretty much mostly Debian based systems with a stint with Fedora and openSUSE (very short stint with openSUSE). In searching for a everyday distro to use, I keep hearing about Arch (and its derivatives) so I decided to give it a whirl. So far it's pretty nice. It's cool to have much more control of my system and the packages I install. I'm still trying to get my network shares to mount using my logon script. I'll search the forums for some answers and see what I'm doing wrong. I'm using the MATE desktop and I'm used to just plopping the script path at the end of the .profile file but it doesn't seem to work at all in the .bash_profile. All in all that's my only real issue so far. Other than that, I enjoying the package manager and everything else.

Hello All,

New to Arch, around 9 years using Linux at home.
Looking forward to learning all I can from the great resources available here while using Arch.
Hope to be able to contribute in some meaningful way sometime down the road.

Welcome, forum newcomers.

jasonwryan is an incredibly knowledgeable guy. I don't think I will ever attain his skill level. He also practices great economy of words. He doesn't waste them. One would do well to thicken one's skin, don't take every terse and direct statement as a personal attack, and to take jwr's advice. If he tells you to read the wiki, he usually provides a link to the specific page on the subject at hand. By doing that, he has greatly narrowed our search. We are expected to dig into the information on our own. This is truly the better way to learn.

Dig in, learn, and enjoy the wonderful world of Arch Linux!

Hi all.

I've always been interested in servers and whatnot, but since I was comfortable using Windows, 90% of my network is Windows based. It started when I got sick of carrying around an external harddrive and wanted to be able to stream my movies around the house. Converted my gaming PC to a file server and it worked wonderfully for 4 years... until a drive died. Luckily I had backups, but it gave me wake up call on backups... Windows kinda sucks at it. Since then, I've moved on from the old gaming PC and I now run ESXi to virtualize everything. Easier to backup everything and run raid for less downtime - it would really suck if I was in the middle of exams and something died... Mostly run Debian VM's now.

Well for my personal laptop, I've been using a 15 inch Macbook and it's been great, nothing to complain... except the size. It's heavy, bulky, and way too much power for school. I wanted to get a cheap, durable, light laptop, but I didn't have the money for a new Macbook. Definitely didn't want to go back to Windows.. and the cheapest thing avaliable was a chromebook. Yeah no. I still wanted a proper computer. I heard about old thinkpads running Linux and it sounded... affordable. I've tried uBuntu and Debian a few times on a desktop, but it just didn't feel right. Then I heard about Arch, a 'bleeding edge' distro with plenty of support (The wiki is amazing). Checked out a few setup screenshots and they looked amazing!

I eventually found an x220 for cheap and I quickly got Arch setup. It worked, but it wasn't perfect. By the time I finished setting it up, school got a bit intense so I let the install kinda get bloated and bad. Lots of random bugs everywhere. Now that I've finished exams, I finally got time to setup Arch the way I wanted and it's fantastic. Reading more about pacman sure did help me figure out the downgrading process, etc. Love the way it works.

Plans for whenever I have time is to get proper backup's going with rsync - I loved Timemachine on my macbook and while I know there's something similar, I like the idea of a full whole system backup more. I also want to figure out how to encrypt the whole partition and lastly get VM's running inside Arch so I don't have to dualboot into Windows if school has a program that's only for Windows.

Thank you,
N

I have Arch and Gnome Gnome on my X220, and it runs perfectly, just for some perspective.

And, hi ^^

hello after hours of effort finally installed arch linux official with deepin as de

eoinfirestorm · 2017-06-14 21:07:23

My name is Jon and I have a problem. It started when a gnome told me about something called Ubuntu, and I thought, "Elementary, what a fun OS to play with". Until someone backtracked and went looking for something Minty fresh. After my journey, I've arrived at the arches of Linux and find myself haunted with possibilities of what I can configure. I joined this forum since as a distro, a strong community backing would make setting up and playing with arch more enjoyable. I'm not uncomfortable with the terminal but I keep realizing that there is more that I don't know about it an find myself consistently learning new things.

Greetings from Italy!
I've been using Linux (mainly Ubuntu and derivates) for a while - say, a couple of year - as ‘casual user’, but since I like to know how things work, to use them better, I decided to try Arch Linux: it seems an opportunity to learn and have a better OS.

So... we'll meet again (and soon) in the Newbie Corner!

Hello,

I just created account, but I'm using Arch for quite some time now. I reinstalled it a lot of times (no special reason like it didn't work, was just playing with configuration) and last time I did was yesterday.
I'm running it on btrfs on luks, one partition for '/' and one for storage (mounted as '/home/storage'. home is on root partition but have Documents, Downloads, etc. linked to storage partition. '/' is on SSD and '/home/storage' is on HDD

I come from Croatia and currently live in Zagreb, I spent most of my life and childhood in Osijek though.
I currently work as junior developer and am 22 years old.

Would like to thank great Arch community that helped me solve my problems many times in past (by finding answer on [solved] forum threads and great wiki)

That would be all (maybe even too much :S) from me
Enjoy!

Texbrew · 2017-06-18 22:50:31

Hello to everyone
this is Ammar from Iraq
iam power engineer
am biggner and want to use this great disto as i checked the websites and youtubes

sorry if sometimes my English not well

thanks in advance

x33a · 2017-06-21 13:28:13

Hi Ammar, welcome to forums. Please be sure to install Arch by reading our official wiki only: https://wiki.archlinux.org/index.php/Installation_guide

It might seem a little difficult at first, but it will help you in the longer run than following third party tutorials.
