Why VI always starts in insert mode? - startup

At some point, whenever I use vi from the command line (windows 10/WSL) it starts up in insert mode, meaning that everything I usually do to navigate ends up adding stuff to the file, wasting time having to clean it up.
I didn't have a vimrc file, and there doesn't seem to be anything in my bash rc files to modify vi behavior. Any ideas what I may have done or any ideas how to stop this behavior? I'm using Ubuntu-20.04
FWIW, adding a .vimrc file with tab related settings didn't change it's behavior. I looked at the /etc/vimrc file, and nothing inside it seemed relevant.

After plowing through google search and trying everything I understand about configuring 'vim' and doing comparison tests, I think:
This behavior is specific to Windows Terminal when opening a WSL terminal. Using WSL's "native" terminal (i.e., clicking the "Ubuntu 20.04 LTS" menu in the "Start" menu) doesn't have this problem.
My original motivation for switching to Windows Terminal is for its multi-tab feature. But this new behavior is crazy -- it works against years of my muscle memory of using "vi", and I'm almost certain that one day I'll accidentally update some configuration file while reading it in "vi". And, I cannot re-train a new muscle memory because all the rest of the UNIX world (e.g., when I SSH into a remote server) hasn't changed. This is like constantly switching between a Mac keyboard and a PC keyboard where the Ctrl key, etc., are in different places.
My solution: I switched to MobaXterm. It has multi-tab support, and is actually richer in features compared to Windows Terminal.

Please run the following:
alias | grep vim
sudo find / -name .vimrc 2>/dev/null
These commands should show you all the places to check, change the alias or fix the .vimrc files found.
Do you find it always going into edit mode, when you vim a file directly and when you use vim as the git commit editor for example?
EDIT:
You could also try which -a vim or whereis vim to see if you have multiple versions. Or failing that sudo find / -name vim 2>/dev/null

here is a better solution. I downloaded the binary.
https://github.com/lxhillwind/vim-bin/releases/tag/v9.0.0978
Put the vim command in /usr/bin/vi
Put the runtime in:
/usr/local/share/vim/runtim
sudo apt remove vim vim-common vim-runtime vim-tiny
sudo apt purge vim vim-common vim-doc vim-runtime vim-tiny
The second line actually gets rid of residual-defaults.
There is also a defaults.vim someplace on the system. I just nuked it.
I went through and made sure there were no aliases or vi or vim configuration files, but still no luck.
This is a horrible solution, but the only thing that is keeping my sanity right now.
vi -c ":imap jj "
You can alias it in your .bashrc. Looking into better solutions.

how do I change default editor for sudo vipw from "vi" to "vim" by tcsh in FreeBSD

When I use command sudo vipw to edit my password file, It's always use vi as editor. I don't like this very much and want to change it to vim.
I already tried:
Add export EDITOR=/usr/local/bin/vim in /etc/profile.
But shell told me "export: Command not found". I thought the reason is export is built-in function only in bash. And I don't want to change my shell.
AddEDITOR=/usr/lcoal/bin/vim in default block of /etc/login.conf
Add setenv EDITOR vim in /root/.cshrc, /.cshrc, ~/.cshrc
All above didn't work at all.
I have google for hours but could not find anything help.
Your /etc/sudoers file doesn't keep your EDITOR environment variable.
I personally have an /etc/sudoers.d/local file, something like
# We don't need to worry about wheel users breaking in to get root access because they already have it.
Defaults:%wheel env_keep+="HOME EDITOR",!set_home,shell_noargs
I'm not sure why this isn't the default, since wheel users have already been given full access. But it's apparently prevailing wisdom to continue hassling them.
Note: If you're using an older /etc/sudoers file that doesn't support an /etc/sudoers.d directory, these lines can be dropped in there... or you could add #includedir /etc/sudoers.d as the last line of your /etc/sudoers file to enable an /etc/sudoers.d directory. Um, yes, the # is a required part of that line, because someone thought it was important for that directive to look like a comment.
Try adding this to the root user /root/.chsrc:
setenv EDITOR vim
or to set it globally to all users using shell tcsh/csh add it in /etc/csh.cshrc
From the man:
A login shell begins by executing commands from the system files /etc/csh.cshrc
and /etc/csh.login. It then executes commands from files in the user's home directory:
first ~/.tcshrc or, if ~/.tcshrc is not found, ~/.cshrc ...
Non-login shells read only /etc/csh.cshrc and ~/.tcshrc or ~/.cshrc on startup.
Also verify vim is installed since is not by default, you could try:
pkg install vim-console
setting the EDITOR or VISUAL environment variable is the key.
if you don't want to go to the trouble of modifying config files (which is indeed the long term solution) then you could sudo su - to get to the root prompt and then you could export EDITOR=/usr/bin/vim before running vipw
There is an empty file called .selected_editor in $HOME (/root).
Remove it and the next call to vipw will ask you to select the editor.

Run script from dock in Mac OS X

I am developing web applications using Ruby on Rails and Sublime Text 3 on OS X 10.8.4. I recently installed the package RubyTest. The tests only work when Sublime is launched using the command
subl
in terminal. Otherwise I get the error message:
/bin/sh: rspec: command not found
I think that's meant to be the case; that's implied in RubyTest's readme file on github.
However I'd like to retain the ability to launch from the dock. Is there a way I can do this?
Unfortunately, OSX applications do not pick up on your $PATH variable set in Terminal. To change the internal PATH settings in Mountain Lion (this method hasn't been tested with previous versions, although it should work), you'll need to edit /etc/launchd.conf:
Make sure you have admin privileges.
Open Terminal or your favorite substitute and see if there's anything in the file /etc/launchd.conf:
cat /etc/launchd.conf
If you get an error like
cat: /etc/launchd.con: No such file or directory
then continue with the next step. If the cat command does display some content, copy it to the clipboard.
Create a new text file with the following content, modified to fit your needs:
setenv PATH /usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin:/Users/YourUserName/bin:/path/to/gems/bin
If the cat command displayed some content in the previous step, paste it into the new file before the setenv PATH command. If it already contains a setenv PATH command, just modify it to add the directories you need, such as /path/to/gems/bin
Save the new file in your home directory (/Users/YourUserName) as launchd.conf.
Go back to Terminal and enter:
sudo mv ~/launchd.conf /etc
to use admin power to move the new file to /etc, replacing anything that was there before. Depending on your previous usage of the sudo command, you may get a short "be careful doing what you're doing" message, but either way you'll need to enter your password. /etc is not directly accessible through the Save dialog unless you're a real power user and know how to get around OSX's file system restrictions.
Reboot your computer
And you should be all set. If you're interested, launchd and launchctl use the csh/tcsh syntax, so you can't use the bash/zsh export PATH=/usr/local/bin:... format.

How to pass env variables to GNOME

I want to replace some utilities(like telnet) with transparent wrappers(with loggers).
At first I used aliases, that worked nicely at the command line but gnome doesn't understand shell aliases so that when people would launch the utilities as the shell for a gnome-terminal profile it would run the actual utility instead of the wrapper.
Then I tried adding new folder with symlinks and prepended it to PATH(security isn't a huge concern plus its a special folder just for these symlinks) in ~/.bashrc but they still run the original(I'm guessing gnome doesn't run .bashrc since it works from the command line). Any ideas where setting path needs to go?
Maybe update-alternatives fits your needs?
I found two ways to do this that seem to work like I want(sourcing scripts for gnome env).
First putting it in ${HOME}/.gnomerc (but I found some places that say you should manually exec gnome session afterwards and others that don't(It seems to work fine without it) and I'm afraid of breaking login.)
Putting it in ~/.profile seems to work so I just
echo 'PATH=~/.symlink_dir/:${PATH}' > ~/.profile
(note that this is ignored by bash if a ~/.bash_profile exists so you may want to manually source it from ~/.bash_profile just in case
echo 'source ~/.profile' >> ~/.bash_profile).
If you really want to use your replacement utilities throughout, you could put symlinks to your replacements in /usr/bin/ (or wherever as appropriate) and move the originals to /usr/bin/originals/ (or wherever).
If you do that, you'd better make sure that your wrappers are rock solid though. Depending on what you're replacing, errors might prevent booting, which is generally undesirable.
It might not be what you are asking, but have you tried changing the commands of the launchers from the menu editor.
If you are using Gnome 3 you will have to download the alacarte package.

Do I need to re-make and re-install couchdb everytime I want to test a change to the source?

I am trying to contribute more with couchdb code, but I have really no idea how it is done the right way.
I have cloned the source from apache git repository and built it with
./configure
make && sudo make install
Then I wanted to change a file from the source called couch_httpd_show.erl
Do I need to run make && sudo make install again for every change I make to the source code and want to see how it behaves?
I am sure there's a more practical way to do it, because this approach is a bit time and patience consuming right?
Yes, there is a shortcut.
./configure
make dev
./utils/run
This builds and runs CouchDB entirely in the current directory. Instead of running as a background daemon, CouchDB will run in the foreground and output log messages to the terminal. It uses some local directories to store stuff: ./tmp/log for logs, ./tmp/lib for databases, and (if I remember correctly) ./etc/couch/local_dev.ini for configuration.
If you run this instead:
./utils/run -i
then you will also have an interactive Erlang prompt, which you can use to help debug.
When I work on CouchDB, I run this in the shell:
make dev && ./utils/run -i
After I change some code, I press ^C, up-arrow, return.
When I joined Couchio, I was responsible for production CouchDB deployments. I asked Chris Anderson for advice about something and he said, "Sorry, ask Jan. I've been just using utils/run for years!"
You can rebuild that one file and drop the output beam in place and restart.
erlc <file.erl>
& then copy the .beam file into place. To restart couchdb use either init:restart(). in the erlang shell or POST /_restart to CouchDB.
Although you might want to consider using the commandline erlang & javascript test suite also to ensure you didn't break anything.

where is my java file?

I'm using ubuntu and I call gedit by using this command:'sudo gedit filename.java'. I'm newbie in ubuntu so now I can not located that file. Ah I'm using windows XP and ubuntu and I have three disk C,D and E in windows XP the fourth disk for ubuntu is not display in windows XP. Can anyone show me where I can find my file? Thank you very much!
Try looking up the command "find". It will locate files.
The next time you need to find a file and you don't know where it is, just use the locate program included with Ubuntu. Sure, your file most likely won't show up immediately in the slocate database, but it's a really good searcher.
Also, the command line and the run prompt assume that the starting point, that is, the current working directory is always "~" unless you've set it differently. That means that all files and paths are relative to your home folder: /home/username for a user and /root for the root user.
Finally, you do not need to use the sudo command for writing code in your own home directory, and thus you can just stick with gedit filename.java. However, if you ever do need to use a graphical application with root/superuser privileges, use gksu for GTK apps and kdesu for KDE apps. sudo is for when you are running an program or need elevated privileges in a terminal.
Type "man find" into the terminal to get a description of how to use the command. But first place I'd look is the home folder. Open up the terminal and type "~" without quotes.
Open a terminal again ( from where you initially typed sudo ) and type ls -l you have to find it there.
