I'm wondering if there is a way set a linux or mac terminal so that you are always entering commands at the top of the terminal screen, and previous commands are below it.
Example
-----Screen top----
>EnterCommand
>PreviousCommand 1
>final line of Previous Command 1 output
>second to final line of previous command 1 output
-----Bottom of screen-----
Thanks!
Such a feature is not built into the standard *nix terminal driver; a terminal application would have to be specifically written to translate newlines and line wrapping into upward motion instead of downward. Note that this will likely break a number of TUI applications, so it is not recommended to use them with such a terminal application.
This seems pretty close to what you're asking for:
https://github.com/swirepe/alwaysontop
To use it run:
git clone https://github.com/swirepe/alwaysontop.git
cd alwaysontop/
source alwaysontop.sh
If you decide you like it just source it in your .bashrc or .bash_profile with something like:
echo "source ~/alwaysontop/alwaysontop.sh" >> ~/.bashrc
Hope that helps!

I'm trying to switch from vim/gvim to neovim on Linux. Up to now my standard workflow started with opening the cli, navigate to my project directory, and run gvim <filename> with the file I intend to start working with.
With neovim I can start it from the KDE menu to get a nice GUI. according to the menu settings, it simply runs nvim with an optional filename parameter. But I don't find the way to run nvim from the cli in a way, that it starts the GUI. Running nvim <filename> simply starts the cli UI.
Google gave me a lot of interesting information, but not, what I'm looking for.
There are different GUIs for neovim. Check which one do you actually use and start it from the command line. Navigate to the KDE menu for neovim GUI, right-click on it and select Edit application... Go to the Application tab and check the Command edit box. There you'll see the actual command which is run by KDE when you select the corresponding menu item. You can create your own shell script or alias which will run this command and use it on the command line.
UPDATE
Maybe some parameter or environment variable is passed to nvim so it changes its behavior. You can try to see what system call KDE actually performs to start the editor. For example, I'm using KDE plasma, so pidof plasmashell gives me the pid which I need. Then:
strace -f -v -e trace=execve -p `pidof plasmashell` &> plasma.trace
After that go to KDE menu and start neovim. Terminate the strace command with Ctrl-C and check the plasma.trace file for the execve system calls made to start the neovim process.
So I was installing node and somehow I ended up in the /user/local/bin folder checking what was there.
I wanted to so a ls | grep node but did a ls | cat node. The node directory then started to show itself in all its glory. I chuckled, laughed, then stopped the cat but that left my terminal looking something like this:
It is easily fixable by exiting the window.
I don't recommend you try it but i've managed to recreate it reliably. Just cat the node directory leave it for a few seconds then cancel it.
My question is what on earth is going on here? AFAIK using cat shouldn't be able to make this stuff happen.
Terminals interpret certain combinations of bytes as commands. This is how command line programs can output colors, or change the cursor position. What you're seeing is the output after one of these commands activated a box drawing character set by accident. You can activate it yourself with echo or printf:
my cool prompt$ printf '\033(0'
└≤ ␌⎺⎺┌ ⎻⎼⎺└⎻├$
To get out of this mess, type reset and press Enter - it will clear the screen and set all settings back to default.
└≤ ␌⎺⎺┌ ⎻⎼⎺└⎻├$ ⎼␊⎽␊├
(..screen clears..)
my cool prompt$
You managed to output the contents of the node executable to the terminal. What happens when you output random octets to the terminal depends on what those characters are and on the terminal. It often leaves the terminal in a state that the user did not really expect.
I am not sure if this is possible but I couldn't find the answer anywhere else or even people who have tried it but my current PS1 is this:
export PS1="\[\e[00;32m\]??\[\e[0m\]\[\e[00;37m\]\n\[\e[0m\]\[\e[01;31m\]\d\[\e[0m\]\[\e[00;37m\] \[\e[0m \]\[\e[01;31m\]\T\[\e[0m\]\[\e[00;37m\]\n\[\e[0m\]\[\e[00;32m\]>\[\e[0m\]"
It is showing up and working upon opening the terminal however I am wondering if it was possible to clear the screen after a command finishes (with a prompt similar to windows cmd 'pause' command if possible) so that it isn't repeated or shown at the bottom of the window
I am running Manjaro XFCE if it makes a difference.
Thanks!
You can try something like this:
PS1='$(echo "(press enter to continue)" > /dev/tty ; read ; clear) $ '
NOTE: You need the redirect > /dev/tty because the standard output of the commands run by PS1 goes nowhere.
Replace the ending $ with whatever prompt you want to show.
I don't really think it is such a good idea. In the short time I've been testing that, it is so irritating!!!
I think you are way better just pressing Ctrl+L befor typing your command to clear the terminal.
I use IntelliJ for most of my Java programming, but every once in a while I need to make certain changes which are much easier done in VIM.
Thus, the question:
While I'm editing a file in IntelliJ, it is somehow possible to tell IntelliJ to start VIM with the same file that is currently under cursor.
Thanks !!
Absolutely!
Go to File -> Settings -> External Tools and add a new one.
Program and Working Directory fields should be self-explanatory. The parameter field should be $FilePath$. Click the Insert macro button to see more token values that you could use.
You can also bind keyboard shortcuts to the external tools you define.
See the help page on configuring third party tools for more info.
Also, see the answers below with helpful screenshots for Windows or Mac.
Even though the original question is about VIM, I'd like to share my settings for GVIM. Especially useful is the parameter used to take it to the current line.
I find it useful to have Gvim open up the file AND take me to the current line. This is done using the following parameters: +$LineNumber$ $FilePath$.
When executed, Gvim should open up and take you to the line you were at in Intellij.
Here's how to set this up with the Homebrew version of MacVim (i.e. the mvim command) on Intellij IDEA 14.
Go to Preferences->Tools->External Tools and click the plus symbol.
Set up the new tool with these parameters
Program:
/usr/local/bin/mvim
Parameters:
+"silent! "$LineNumber$"|norm! zz" $FilePath$
Working Directory:
$SourcepathEntry$
For macOS 10.12+ users, If you want to open it in iTerm2, here is a latest solution:
#!/bin/sh
vim="vim $1"
osascript -e "
tell application \"iTerm\"
set myterm to (create window with default profile)
tell myterm
activate current session
launch session \"Default Session\"
tell the current session
write text \"$vim\"
end tell
end tell
end tell
"
Date: Apr 5, 2018
iTerm2: 3.1.5
IntelliJ IDEA: 2018.1
https://gist.github.com/backslash112/open_vim_in_iterm.sh
This was somewhat more involved on the Mac OS X (Lion), especially if you'd like to use Terminal.app
The only difference on Linux is the shell script would be much simpler... (really it'd be simple to not even use a shell script for this on Linux, with a terminal that accepts the -e argument!)
Here's my working solution:
#! /bin/sh
vim="vim $1"
osascript -e "tell app \"Terminal\"
activate
do script \"$vim\"
end tell"
I am using these parametrs for launching vim: +$LineNumber$ --remote-tab-silent "$FilePath$". It allows you to open each new file in vim's tabs. Works fine)
Go to Settings -> Tools -> External Tools
Click the + to add a tool.
Here are the settings I use:
Name: Vim
Program: /usr/bin/gvim
Arguments: --servername $ProjectFileDir$ --remote "+call cursor($LineNumber$,$ColumnNumber$)" $FileDir$/$FileName$
Working directory: $ProjectFileDir$
I turn off "Open console for tool output".
The arguments will use Vim in client-server mode, so if you jump to Vim from IntelliJ in the same project dir multiple times, the existing Vim instance will be reused, and they will also place the cursor in Vim exactly where it is in IntelliJ.

I have experienced some bugs but for the most part it works.
I'm having some problems working with my development environment. Specifically, after I invoke the screen utility from within Cygwin I lose the ability to do tab completion. Before I invoke screen however tab completion works just fine.
I messed around with setting different values for the TERM env variable (VT100, xterm etc) but without success. It must be something trivial but I have no idea anymore. Does StackOverflow have any suggestions for me?
when you issue 'screen' from inside cygwin it might put you in another shell like /bin/sh instead of /bin/bash (and bash is where you're getting the tab completion from).
To fix the problem you could edit your .screenrc file (found in your home directory) and add in this line:
shell bash
Then try running screen again and you should see tab completion work within this new window.
The problem is that bash needs to be run as a login shell in order to have tab completion in the default cygwin setup. If you run bash in a cygwin bash you won’t have tab completion either. To set screen to run bash in login mode, add this line to your ~/.screenrc file:
shell -bash
I had a similar problem with git autocompletion not working when using screen on a linux machine, but wasn't due to a different shell. I fixed it using this question: Git autocomplete in screen on mac os and doing the following:
Get the git autocompletion script
curl https://raw.github.com/git/git/master/contrib/completion/git-completion.bash -OL
why would you want that hanging around?
mv git-completion.bash .git-completion.bash
add this line to your ./bashrc
source ~/.git-completion.bash
Then in your terminal
source ~/.bashrc
That worked for me.
(I imagine after three years you've probably solved your problem, but I hope this helps someone else)
