@DavidFoerster Grats David, every single one is well deserved :)

user716691

11:46

what does this command do mkdir ~/.npm-global

create a hidden directory npm-global but where ?

dessert

@DavidFoerster congrats!

@user716691 in your home directory, the one shown by echo ~, with the format /home/YOURUSERNAME

user716691

@dessert oh thanks but suppose if I want to create a directory at root then what should I type

dessert

@user716691 then you should do e.g. sudo mkdir /.npm-global

user716691

@dessert ok thanks , I already have a directory but its not hidden ,can i make it hidden directly or do i need to delete it and then create a new hidden directory of same name ?

dessert

however, as you can see by the sudo, creating a directory there is nothing a user normally needs to do or should do without knowing what they do

you can do mv your_non_hidden_directory .your_now_hidden_directory

user716691

11:52

actually installing node ,going through the steps given here : docs.npmjs.com/getting-started/fixing-npm-permissions

the problem is i need a hidden directory of same name

.npm-global

i have a npm-global directory in my home folder

following steps i need to follow :

Make a directory for global installations:

mkdir ~/.npm-global
Configure npm to use the new directory path:

npm config set prefix '~/.npm-global'
Open or create a ~/.profile file and add this line:

export PATH=~/.npm-global/bin:$PATH
Back on the command line, update your system variables:

source ~/.profile

dessert

then why do that in /? it seems like a good idea to install under ~/…

user716691

@dessert yeah ,i just asked for curiosity but actually intended to install it in home so ,need to know how to make a regular directory already existing into a hidden one

dessert

so you have a directory npm-global and want to rename it to .npm-global? that’d be:

mv npm-global .npm-global

assuming you’re working in your home directory, else first change to there with cd ~

user716691

@dessert but as I know mv is used to move a directory ,is it also for renaming it ?

dessert

or give absolute paths: mv ~/npm-global ~/.npm-global

user716691

12:01

??

dessert

@user716691 there’s actually no moving if you stay in the same filesystem, it’s all renaming :)

user716691

@dessert oh thanks i didn'

dessert

so yes, mv also renames

user716691

t know this before

@dessert oh ok thanks i didn't know it before

:)

dessert

happy to help :)

user716691

12:04

@dessert but further have a query why it is suggested to have a hidden directory ,i mean why not a normal one ?

can you suggest any reason ?

dessert

@user716691 that’s just because you don’t really need to alter this directory directly any more once the installation is done, so why see it every time you open your file browser?

dessert

the same with the .config directory: it’s a good thing to store config data in your home directory, but you don’t need and presumably don’t want to see it

you can very well use a normal, un-hidden directory as well if you want, hiding it is just a convenience thing

user716691

ok got it .now the next step given is Configure npm to use the new directory path:

npm config set prefix '~/.npm-global'

which can be done simply by giving upper command

then it says Open or create a ~/.profile file and add this line:

export PATH=~/.npm-global/bin:$PATH

i don't know how to open a file and change something into it .

should i just use cd command and go into suggested dir

like cd .profile ?

??

Benny

it's easy to do it, simple open terminal and type

gedit ~/.profile

then edit, close, reboot. done.

user716691

12:16

@Benny oh great thanks !

:)

@Benny i have a question i have installed my nodejs/npm at /opt/node-v8.11.2-linux-x64

what is suggested For many POSIX systems, this will be /usr/local.

DANGER: If the path is just /usr, change the default folder to a new one as described in the npm documentation.

so want to know should i continue with /opt/node-v8.11.2-linux-x64 or should i move it at /usr/local/ as given ?

which would be more apt

?

@dessert need your suggestions too here

Benny

it's ok /usr/local is in your PATH, just try to put it and see the results

dessert

TBH, I’d just follow the instructions…

user716691

ok

when i tried to use this command :

mv ~/opt/node-v8.11.2-linux-x64 ~/usr/local

it says no such directory exist so should i use

mv /opt/node-v8.11.2-linux-x64 /usr/local

??

@dessert please suggest

@Benny plz suggest

dessert

12:36

Well did you install in ~/opt/… or /opt/…? That’s not the same!

the instructions talk about your root directory /, not your home directory ~/!

user716691

after giving command :

npm config get prefix

it says this :

/opt/node-v8.11.2-linux-x64

dessert

well why move it then?

user716691

so it seems its in root ,hope i am not wrong

dessert

it is indeed :)

user716691

means ,as par as its given it suppose to be at /usr/local rather /opt/??

i am getting confused here

@dessert isn't it ?

dessert

12:39

could you provide a link to the instructions please?

generally, never touch a running system ;P

user716691

here are the instructions :

https://docs.npmjs.com/getting-started/fixing-npm-permissions

or otherwise i am stating everything here by copying ,just give me a sec

To minimize the chance of permissions errors, you can configure npm to use a different directory. In this example, it will be a hidden directory on your home folder.

Back-up your computer before you start.

Make a directory for global installations:

mkdir ~/.npm-global
Configure npm to use the new directory path:

npm config set prefix '~/.npm-global'
Open or create a ~/.profile file and add this line:

export PATH=~/.npm-global/bin:$PATH
Back on the command line, update your system variables:

dessert

read that, but it doesn’t talk about /opt/ or /usr/local/ – or am I missing something?

user716691

the link was referred through another page which states the following :

Configuring npm
You will need to do this if you get a permission error when you try to install npm modules. If you don't have permission errors, then skip this configuration. You can come back to it and configure later.

Locate the path to npm's directory. It might differ depending on the OS. Execute the command below to find your path:

npm config get prefix
For many POSIX systems, this will be /usr/local.

DANGER: If the path is just /usr, change the default folder to a new one as described in the npm documentation.

here the npm documentation is actually a hyperlink referring to the upper instructions page as I said earlier

dessert

if you want it the apt way, install it using apt:

sudo apt install npm

problem solved :)

Mitchell van Zuylen

Hello guys,

dessert

12:44

wow, it’s crowded in here today

hi :)

user716691

@dessert haha i know it sound easy but then you don't learn a lot , i prefer to install it on my own rather a third party package installation ,so i need your help here :(

Mitchell van Zuylen

I'm running a server, which I use as a host for a guest ubuntu 12 virtual machine. The memory of the guest was too small, so now I tried to increase the size

user716691

Hi Mitchell

dessert

@user716691 it doesn’t say you should move anything, or does it?

Mitchell van Zuylen

Now the VDI it's running on is 800 gb instead of the initial 200. I'm not sure how to proceed from there. If I log into the guest, it still thinks it's only 200gb.

dessert

12:46

i think /opt/ is just fine :)

Mitchell van Zuylen

lsblk shows me that dva is still the original 200gb

user716691

@dessert what it suggest that it should be there at usr/local and i have it at /opt/ so want to move it from /opt/ to /usr/local

Mitchell van Zuylen

I though it was because the newly added 600gb was unallocated, I tried to use cfdisk, but it still shows the original 200gb only. Any thoughts?

dessert

@user716691 what makes you think that? this “many POSIX systems” thingy? well, it says nothing more than that…

don’t move directories around randomly in your root directory and expect your system not to break :)

Benny

@user716691, Hey, sorry, I am at work now and can't help so much.

user716691

oh ok , well i got your point ,and simultaneously i searched about the difference between /opt/ and /usr/local and i got this link :
https://unix.stackexchange.com/questions/11544/what-is-the-difference-between-opt-and-usr-local

where somebody said that /usr/local, for self, inhouse, compiled and maintained software. /opt is for non-self, external, prepackaged binary/application bundle installation area.

so i feel /opt is good enough to have node/npm no need to move it to /usr/local right ?

as it certainly unbundled means not part of OS

Takkat

@MitchellvanZuylen you need to partition and format the drive after growing it. If you had not booted from it you can also grow the first partition. Both is best be done from gparted running a live system in the VM. Make a backup/snapshot before you start!

user716691

@Benny no problem , @dessert is available and helping me ,still thanks :)

dessert

@MitchellvanZuylen I’m not ignoring you, I just don’t know how to help you. ;)

Takkat

12:54

@dessert: too bad because I am at work too - this means very little to no time ;)

dessert

well I’m at (home office) work too

just that me being here means insufficient self control in my case :(

Mitchell van Zuylen

@dessert np, thanks anyway!

Takkat

here it is a real office with many co-workers and a boss who may pop in any time. Me dead quiet then

Mitchell van Zuylen

@Takkat Thanks. Just to make sure I understand, I should run gparted from the guest, and not the host, right?

dessert

@user716691 right.

Mitchell van Zuylen

12:58

Okay, I'll give that a try. Thanks!

Takkat

@MitchellvanZuylen you run it in VBox from a live ISO mounted to your VM - then you can "see" your VDI

bit of letter shuffling here

dessert

@Takkat do you work with natural and/or computer languages?

user716691

@MitchellvanZuylen you can check this post of mine ,may be it can help

https://askubuntu.com/questions/938910/how-to-resize-root-to-increase-home-partition-size-in-ubuntu-16-04-with-gparted

@dessert oh thank you so much :) you are a great help :)

Takkat

@dessert I take them all :D - no it is natural here at work.. Computer is only a tool.

dessert

@user716691 you’re welcome :)

Mitchell van Zuylen

13:01

@Takkat @user716691 Thanks! If I do this, what happens to data currently on the disk?
E.g. it had 200gb of data, I increased the dvi to 800. If I use parted, does that retain the original 200gb of data?

Just checking before I accidentally delete all my data haha

dessert

@MitchellvanZuylen good thinking ;)

Fabby would say: Backup thrice before proceeding!

user716691

@MitchellvanZuylen well its recommended that you should back up your data but in my case when i did same i didn't backed it up and my data was safe but still would recommend to have a back up :)

Takkat

@MitchellvanZuylen snapshot/Backup!!!

dessert

I think you got the picture. ;)

Mitchell van Zuylen

Cool, thanks guys! Installing gparted now.

user716691

13:04

Mitchell van Zuylen

It's extra 'fun' since I only got terminal access to my guest (and host actually..) and all the guides are for the GUI's haha

@PiMathCLanguage it does work as I know

mhhh because I have still this problem, I am using Linux Mint 18.2 XFCE (which is based on 16.04)

I mean pasting to terminal works, but copying from terminal not

Takkat

@MitchellvanZuylen you don't have physical access to the host - then it is more complicated. Can you clone your VM?

dessert

@PiMathCLanguage did you try marking the text with the mouse and pressing Ctrl+Shift+C?

PiMathCLanguage

yes, I did

also something weird, when I open a new terminal, copying and pasting is working again

but in the previous opened one, copying still not woks

user716691

@PiMathCLanguage then simply leave that terminal ,its simple :D

Hello :)

Mitchell van Zuylen

@Takkat, I only have access over SSH. I think I could clone it, why? (I need to run now, meeting starting in 5 min) THanks for all the help so far!

PiMathCLanguage

but I need to copy from the other terminal something because I need to copy some outputs from there

I mean, I will open another one, but this problem will still occure some time

any permanent solution to this?

Takkat

@MitchellvanZuylen for CLI use parted to partition and mkfs to format. This will give you an extra partition which you will have to mount then to be able to use.

cl-netbox

Hey @Takkat nice to see you ! :) Everything fine ?

Takkat

If you want to grow the existing drive you can't boot from it - then you need to boot another Ubuntu VM to mount the drive to there. All not so convenient without a GUI or physical access-

@Takkat Same with me ... quite busy. :)

user716691

@PiMathCLanguage have you tried to copy outputs to some other file like text file ??

PiMathCLanguage

@user716691 you mean mark / copy from terminal and then paste to a text file (in an editor or so)?

I tried to paste it to some places, does not work

except for the new opened terminal, but I would really like to know, when and how this happens

user716691

13:36

@PiMathCLanguage yes ,if that works then that way you will be capable of copying what you need and then simply close your old terminal , look sometimes system need to updated ,reboot to have changes in action , and you yourself said its not working in old terminal but working in new one so it might be something system not getting correctly in old one

PiMathCLanguage

probably, yeah

cl-netbox

@PiMathCLanguage looks as if the clipboard functionality is (partly) broken on your system.

PiMathCLanguage

@cl-netbox that could be too

dessert

or the “C” key hangs ducks

cl-netbox

@PiMathCLanguage does it work after rebooting the system ? might solve the problem.

PiMathCLanguage

13:38

@cl

cl-netbox

yes ?

PiMathCLanguage

@cl-netbox I have not tried it yet, because in the new terminal copying is working again

sorry my fault (was pressing enter too soon)

cl-netbox

@PiMathCLanguage please check it out ... reboot the system and look if it works correctly afterwards.

PiMathCLanguage

okay, I will try it later on (have some work going on)

cl-netbox

@PiMathCLanguage good luck ! :) I hope it solves the problem ... often it does in such cases.
