I can't use the mtools command on Minix 3.2.1, i tried installing all the packages whit pkgin-all but didnt work, still saying mtools: not found when trying to use it
How can I install it?
In MINIX 3.2.1 Mtools are not supported anymore. I don't know why they did that. I believe you are using Mtools for file transfer between MINIX to other operating systems. Well there is very easy method now. You have to use openssh ( networking thing ) for that. Just install openssh and login your MINIX 3 system with a ssh client. Here is an article " Install openssh on minix 3"

I am using asdf + asdf-erlang as my version manager for Erlang. All seems to be working fine, except that typing erl -man mnesia results in No manual entry for mnesia.
I have installed all dependencies mentioned on the asdf-erlang github page. I have also installed xsltproc and fop. Unfortunately "man" folder located under ~/.asdf/installs/erlang/18.3/lib/erlang/erts-73/ is empty. I haven't found man pages being generated elsewhere.
I was trying to locate build log, but I was not successful with that either.
I am using 64bit Ubuntu 16.10 & 16.04.
OK. I finally managed to resolve the issue:
Go to https://www.erlang.org/downloads/ and download manpages for the version(s) of Erlang you have installed using asdf (so for 18.3 you're looking for: http://erlang.org/download/otp_doc_man_18.3.tar.gz)
Copy man folder with its content (extracted from the archive) to ~/.asdf/installs/erlang/<version>/lib/erlang/. After doing so, you should have .~/asdf/installs/erlang/<version>/lib/erlang/man containing man1, man3, man4, man6, man7 (and each of those folders should have some manpages in it).
Repeating steps above for all the versions installed using asdf, allows you to use manpages for specific version of Erlang you are using at the moment.
looks like erlang-manpages are not included in the asdf-erlang since you are using ubuntu i would suggest you add Erlang Solutions repository to your system, call the following commands:
wget https://packages.erlang-solutions.com/erlang-solutions_1.0_all.deb
sudo dpkg -i erlang-solutions_1.0_all.deb
sudo apt-get update
then install erlang-manpages:
sudo apt-get install erlang-manpages
you could also install erlang-doc — HTML/PDF documentation
sudo apt-get install erlang-doc
check this page for more information
The man path in #MaciekTalaska 's answer seems not correct, it does not work at all, for erlang 18.3.
After reading ASDF's activate script(), here's one statement:
_KERL_MANPATH_REMOVABLE="$HOME/.asdf/installs/erlang/18.3/lib/erlang/man:$HOME/.asdf/installs/erlang/18.3/man"
Therefore, you just need to:
Go to https://www.erlang.org/downloads/ and download manpages for the version(s) of Erlang you have installed using asdf (so for 18.3 you're looking for: http://erlang.org/download/otp_doc_man_18.3.tar.gz)
Copy man folder with its content (extracted from the archive) to $HOME/.asdf/installs/erlang/${version}, but not $HOME/.asdf/installs/erlang/${version}/lib/erlang/ (in fact, there isn't a folder named erlang under lib).
I'm trying to set up a Ruby on Rails environment within OpenSuse, but I've encountered a problem. When running sudo zypper install rubygem-railties-3_2 all I get is File '/repodata/repomd.xml' not found on medium 'http://download.opensuse.org/repositories/Banshee/12.1/'. So something seems to be wrong at their side.
Is there anyone who as a workaround for, or more info about, this problem?
When running the command $ sudo zypper up I was receiving a similar error:
File ... not found on medium http:// ...
Detailed error:
File './x86_64/libxkbcommon0-0.7.2-48.2.x86_64.rpm' not found on medium 'http://download.opensuse.org/repositories/KDE:/Qt5/openSUSE_Leap_42.3/'
The solution which worked for me was to run $ sudo zypper ref before running $ sudo zypper up
Obviously, you have setup an additional repository for Banshee for a very old opensuse version. Opensuse only keeps its repositories alive for the last two two releases to the current release. For this reason, you get this error. You can disable or remove the repositorium to resolve the error.
In order to install packages that are not part of the currently configured repositories, it is the easiest to use the one-click install available at https://software.opensuse.org/search .
I am attempting to follow instructions on this page:
http://www.agilereasoning.com/2011/05/25/ruby-on-rails-on-windows-7-using-cygwin/
I have been trying to install Rails with varying success first using the railsinstaller and I encounter difficulties like no vim and I couldn't copy and paste from the Windows command prompt so I install CYGWIN. It didn't download the files correctly so I downloaded them manually and some were hard to locate. I couldn't find the final package as a .tar file so I downloaded libxslt-devel-1.1.20-1.i386.rpm.
Right click the Cygwin shortcut and choose edit from the menu. Change the contents to >match:
1 #echo off
2 C:\cygwin\bin\rxvt -sr -sl 1500 -e C:\cygwin\bin\bash.exe --login -i
Do I have to put this as a command to run on the executable or inside the cygwin commmand prompt? When I try to do that I get this:
-bash: 'command': command not found
Lots of things wrong here.
You can copy/paste the command prompt with Edit->Mark or Edit->Paste
libxslt-devel-1.1.20-1.i386.rpm is a linux file.
C:\cygwin\bin\rxvt - why are you mesing around with rxvt?
I recommend you install the rubyinstaller + devkit and then do gem install rails. However don't expect to be happy with rails' performance on windows.
Ruby on Rails on Windows via CYGWINTry:
Install Vagrant
Virtual Box,
and Cygwin (or PuTTy, I am using Cygwin).
With this set, open Cygwin, go to your project folder, run vagrant init <box> (my box is hashicorp/precise64 - see others)
(you may also want to cfg your Vagrantfile?). All set, Run: vagrant up and vagrant ssh
Now you have a virtual machine (Ubuntu) running, and you can install rvm (recommended... so you can have different versions of Ruby), or go directly with ruby, rails, etc.. (sudo apt-get ruby -v x.x.x,etc)
- Vagrant "creates and configures lightweight, reproducible, and portable development environments".
- Cygwin helps with ssh issues, etc...
- Virtual Box manages the machine (Ubuntu, or other OS)
With this set, I have no problem at all running Ruby (on Rails) with Windows.
I've just installed Cygwin on Windows 7 to develop RoR apps with, trouble is I am trying to connect Git with my Github account through Cygwin but for some reason when I run the command ssh-keygen -t rsa -C "myemail#etc.com" it gives me back the message "bash: ssh-keygen: command not found"
I am following the Ruby on Rails Tutorial by Michael Hartle by the way but can't seem to find a solution.
Can anyone offer any advice?
Chances are you probably forgot to install the openssh package when you installed Cygwin.
I've used this guide before, and everything was flawless(for ssh):

In my application directory (on Windows) I run:
sudo pdfkit --install-wkhtmltopdf
as explained here, but I got this error:
'sudo' is not recognized as an internal or external command,
operable program or batch file.
What could be the problem ?
Sudo is a Unix specific command designed to allow a user to carry out administrative tasks with the appropriate permissions.
Windows does not have (need?) this.
Run the command with the sudo removed from the start.
sudo is a Unix/Linux command. It's not available in Windows.
sudo is used for Linux. It looks like you are running this in Windows.
That you are running Windows. Read:
http://en.wikipedia.org/wiki/Sudo
It basically allows you to execute an application with elevated privileges. If you want to achieve a similar effect under Windows, open an administrative prompt and execute your command from there. Under Vista, this is easily done by opening the shortcut while holding Ctrl+Shift at the same time.
That being said, it might very well be possible that your account already has sufficient privileges, depending on how your OS is setup, and the Windows version used.
sudo is a command for Linux so it cant be used in windows so you will get that error
Sudo is a Unix specific command designed to allow a user to carry out administrative tasks with the appropriate permissions.

Yes, windows don't have sudo on its terminal. Try using pip instead.
Install pip using the steps here.
type pip install [package name] on the terminal. In this case, it may be pdfkit or wkhtmltopdf.
Analogue to sudo in Windows is running command prompt "As Administrator" by right-clicking on it's link. Then everything you run in it will be "sudo-ed".
sudo is not for windows, its for unix/linux.
option 1: install ubuntu cli software (not OS) in windows, here is the windows store link: https://www.microsoft.com/en-in/p/ubuntu-2004/9n6svws3rx71. After installing you can use ubuntu's cli in your windows where sudo will work.
option 2: install and use gem (ruby on rails) for installing wkhtmltopdf-binary
gem install pdfkit
gem install wkhtmltopdf-binary
ref: https://github.com/pdfkit/pdfkit
option 3: you can use npm or python for wkhtmltopdf insted of ruby on rails, both modules (nodeJS python) works fluently and compatible with windows:-
https://www.npmjs.com/package/wkhtmltopdf
https://pypi.org/project/wkhtmltopdf/
