[13:48] next [13:48] What is the difference between vi and vim, it looks the same? [13:49] neer, for most systems yes, but vi used to be the old one, vim is newer. [13:49] vi enhanced [13:49] next [13:49] So, do we have to refer the whole thing from the log? And this is just going to be a q/a session? [13:50] ! [13:50] skarpy, you will have to try the commands from the log, if you have questions, we will take it here.

[13:52] thanks [13:52] poojaencoded, 2 things, you are talking out of order, also use a pastebin like paste.fedoraproject.org to show so many lines [13:52] soumam_, correct, but think about a situation where you will have to login to a server and work [13:53] and also vim is very powerful [13:53] poojaencoded: yes and chhose vim [13:53] next [13:53] ! [13:53] ok, kushal !we will learn its power :) [13:53] poojaencoded, yes, install vim [13:53] next [13:53] Edit mode turns on with a/d/w keys also. Why is that?

[13:58] next [13:58] kushal: what's difference between :wq and :x command ! [13:58] zetathon__, or in the mailing list [13:58] My question is not related to vim rather it's bash scripting related from previous day. Can I ask it now? [13:58] ok [13:59] ! [13:59] iKshitij, noting that I know about, expect :x is one character less to type :) [13:59] arush, ask [14:00] next [14:00] kushal, Is working with hjkl is more preferable or with up-down-key-left-right key during editing in vim? [14:00] asraisingh, most of the vim users use hjkl [14:00] asdofindia, but again, personal choice [14:00] next [14:00] this error is popping: [14:01] !

[14:02] saikat_, first become root, sudo su - [14:02] tell when you are ready [14:02] I am root [14:02] asraisingh: I used to prefer nav key but when you start touch typing you don't want your finger to move to nav key. Hjkl seems easy :) [14:02] saikat_, then these two command one by one [14:03] dnf remove vim-minimal [14:03] dnf install vim sudo -y [14:03] asraisingh, https://www.flickr.com/photos/kent-chen/6825667892/ will give you more details :) [14:03] next [14:03] I do not have any question i just have a little request please send all the link for home work at the end of the session so i will only read those only. [14:03] kvy, Nope, we will not do that. [14:04] can i ask why? [14:04] ! [14:04] kvy, It is the duty of the participants to read the logs. [14:04] !

[14:05] kushal, getting this error on 1st command: Error: The operation would result in removing the following protected packages: sudo. [14:05] kvy: what you can do is write a script which filters the URLs alone from the log. [14:05] kushal, oh got it. [14:05] saikat_, not error, it is asking to press Y or N [14:05] press y [14:05] next [14:05] like instead of having 'h' to move left one character, Can we change? [14:05] Whats a visual mode? [14:05] ahole[m] no just the homework [14:05] im_mohsin, I don't know if that is possible [14:05] ahole[m], sounds interesting will try for sure [14:06] Out of context but where are these buffer editors used ? I know in servers we use them because they are light weight. [14:06] kushal, it does not say type y/n. pressed y, nothing happens [14:06] ok. Thanks. i thought it would good to arrange keys in sequence [14:06] saikat_, dnf remove sudo vim-minimal [14:06] what does it do? [14:07] next [14:07] Cyber_freak: you can use it day to day job also, depend on your preference [14:07] im_mohsin, Nope, there is a reason for those keys :) [14:07] dodococo, wait for that answer [14:07] ! [14:07] im_mohsin: I think you can edit vimrc to remap your keys [14:08] ! [14:08] ahole[m]: copying the logs in a txt file and just give a search like find in notepad will also do.In command line we can use grep for http [14:08] kushal, this error: [root@localhost ~]# dnf remove sudo vim-minimal [14:08] Dependencies resolved. [14:08] Error: The operation would result in removing the following protected packages: sudo. [14:08] [root@localhost ~]# ^C [14:08] Will get the pastebin after this session [14:08] stop flooding please. I cannot follow [14:08] soumam_: You'll have to run it everyday. [14:08] kushal, saikat_ it's the same on my fedora 26 beta VM. I think you can do sudo dnf remove vim-minimal without root, then become root and do the second line [14:08] dodococo: http://vimdoc.sourceforge.net/htmldoc/visual.html#Visual it will contain document around visual mode. [14:09] saikat_, you don't have to get the pastebin, just paste in paste.fedoraproject.org [14:09] saikat_, are you on F25? [14:09] yes [14:09] saikat_: use sudo dnf remove vim-minimal [14:09] saikat_: you did it wrong [14:09] ahole[m], that´s a 2 second job man :) [14:09] saikat_: you are removing sudo! :) [14:10] soumam_: I guess I am the lazy one. [14:10] iKshitij, yes, that will happen in this case [14:10] praveenkumar, same error with your command [14:11] dodococo, i look into it :) [14:11] saikat_: can you use pastebin and put what you tried and also error. [14:11] praveenkumar, okay [14:11] sounam, making a script and executing it would be a good learning curve if not done already [14:12] ! [14:12] dodococo, I will show in few minutes [14:12] next [14:12] This is regarding the change and delete. How can I press cw? When I press c the edit mode is turned on. [14:12] saikat_, and you also wait [14:12] ashwanig, it should not [14:13] kushal, yes. [14:13] ashwanig, press escape first [14:13] vipulgupta2048_ yes of course after i will learn python.I will do everything by script :) [14:13] ashwanig, Ah, you should be in the command mode. [14:13] you need to go in the command mode [14:13] Please stop talking about the other random things. [14:13] kushal, Sorry, my bad. [14:13] kushal :P [14:13] abhinavshirur, Good catch. [14:13] next [14:13] How to remove a PPA (repository) completely ? I have read the answers on forum but after doing ppa-purge, sources.list still shows the repositories. [14:13] kushal: sorry my bad. [14:14] ! [14:14] vipulgupta2048_: do you mean remove all PPA repo you have added? [14:15] vipulgupta2048_, sorry, I don't know about Ubuntu that well, can anyone else reply?

For installing Visual Studio a PPA was installed. I uninstalled vscode but the PPA still was left in the system and showing in sources.list in apt [14:16] anupamas, do you have more than one line in the file you edit? [14:16] anupamas, may be because you are in the first line. j and k to shift lines [14:17] yes schubisu [14:17] you need to have lines spread across the file, anupamas [14:17] ! [14:17] ! [14:17] vipulgupta2048_: it's possible, you would like to remove all the ppa. This is because it searches the PPA everytime when looking for packages [14:17] vipulgupta2048_: afaik, PPA are same as repo in Fedora [14:18] vipulgupta2048_: it's better maxking answers this, he uses Ubuntu [14:18] difficult to simultaneously follow the discussion here and also read from the log file! [14:18] saikat_: are you not able to install vim? [14:18] sayan, Yes [14:18] and also difficult to wait for ur turn [14:18] !

[14:19] precise* [14:19] saikat_: login as root and remember don't log out of root until and unless I tell you [14:19] like :u is for undo, then what does :r do? [14:19] saikat_: I will tell you the steps one by one, okay? [14:19] saikat_: try man vim and see the first line. [14:19] sayan, yes, thank you, i am logged in as root [14:20] :r replaces and :u is for undo [14:20] Yes I know, In the software menu PPA installed by the users are shown separately. I just want to know the best way to remove them (one particularly), maxking [14:20] ! [14:20] sayan, first line says vim - Vi IMproved, a programmers text editor [14:20] samridhia, No its not replace [14:20] ! [14:20] its doing something else only [14:20] ! [14:20] saikat_: you have vim with the alias vi. [14:21] zetathon__, try that [14:21] :r is copy pasting the same stuff again [14:21] okay got it [14:21] next [14:21] like :u is for undo, then what does :r do? [14:21] saikat_: check pm [14:22] ahole[m], so do i need to upgrade it or what? when i try to open txt files, it opens with regular txt editors [14:22] I tried but, I dont know whats heppening [14:22] zetathon__ caps lock? [14:22]
