Cygwin : typing characters can't display after popup browser - cygwin

I want to run activator from play framework(www.playframework.com).
When i type activator, the program will run and popup browser. When i closed or hided the browser, I continue to use cygwin bash for other commands.
But when i try to type, i can't see the characters\text\command that i'm typing. When i hit enter, i can see the bash response output to what i've typed.
I also try to re-install and it gave the same problem.
What could be the problem? do i miss some setting? i'm using win8.1 pro 64bit and install latest cygwin with default selection.

I had this same issue with the following configuration:
Cygwin on Window 7 64 Professional
Typesafe Activator 1.2.3
Oracle JDK 1.7 64
So, this is how I've managed to solve this problem, and so far I didn't noticed any collateral effects:
Edit "activator" shell script:
[PATH_TO_YOUR_INSTALLATION]\activator-1.2.3\activator
Comment the following line (around #220) from:
# stty -icanon min 1 -echo > /dev/null 2>&1
Another option
If don't want to edit this file, just run (blindly) the follow command, and echo start working again:
stty icanon echo
That's it!

BSD script command prevents a terminal from recognizing its size. How can I fix this?

I’m using script command to record a terminal log all the time. It’s a useful command, but a terminal size isn’t reflected when I change it because of this command.
Let’s say I change a terminal size without using script command.
Before I change it, stty command, which confirms or reflects a terminal size, shows as follow.
$ stty size
53 200
Then, I will change a terminal size.
$ stty size
35 158
You will see my terminal size has changed.
Next, I will change a terminal size with using script command.
Before I change it, stty command shows as follow.
$ stty size
53 200
Then, I will change a terminal size.
$ stty size
53 200
stty command doesn’t recognize my actual terminal size when using script command.
This causes the appearance of some command is broken, such as less or vim.
I know stty command has ability to reflect a terminal size as follow.
$ stty rows <ROWS> cols <COLS>
But I’m too lazy to execute this command above every time I change a terminal size.
Originally, stty command should recognize terminal size changes automatically. But script command does something bad I think.
How can I fix this problem? Or could you please let me know the alternative?
Here’s my environment:
script command BSD December 4, 2013
macOS Big Sur 11.4
iTerm2 Build 3.4.8
zsh 5.8 (x86_64-apple-darwin20.0)
I haven’t tried GNU version of script command yet, but it seems that GNU version of it can’t be installed on a Mac computer.
I have tried on Terminal.app as well, but the same problem occurred.
Thank you in advance.

Alter Behavior of xdg-open

I use the command xdg-open quite a lot in my Ubuntu Linux terminal. However, two things irk me:
Is it possible to suppress the error messages?
Is it possible to get the command to always complete? (That is, not continue running, so that I have another "new line" in my terminal).
I realize 2 may not be possible, because of the way the program works, but I imagine 1 is.
First one is easy. Just
alias xdg-open="xdg-open 2>/dev/null"
If you want it permanently, just add that line to ~/.bashrc file.
I recommend you to think twice if you want to become blind to errors, though.
The second one is quite confusing to me. xdg-open shouldn't be intereactive. In my computer (Debian sid) xdg-open execs the command and ends, even if the command itself has not ended (ie: you have not closed the application opened for the URL). I think this should be the behaviour of xdg-open on any platform (it's supposed to work exactly the same way on any XDG system, that's its very purpose).
Anyway, for any command you launch in a shell, if you want it to be non-interactive, that is, to allow to enter commands even if the previous one hasn't finished, you just attach "&" to the end of it. Example:
# prompt is not shown until you close the calculator
$ gnome-calculator
# prompt is shown right after opening calculator and you can
# work on the shell even if you don't close it
$ gnome-calculator &
I maybe late for the answer, but I got exactly the same problem like you have / had.
I tried to start a URL with xdg-open, my default browser is firefox, and not xdg-open but firefox started with an error:
[user#user-pc ~]$ xdg-open https://www.google.de # the page opens fine, but firefox had an error
[user#user-pc ~]$
(process:3783): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed
# needed to press enter here
xdg-open closed fine but the firefox error stayed and I need to press enter to get the bash moving.
To get along this problem I called xdg-open within a new shell putting those output to /dev/null:
bash -c "xdg-open https://www.google.de" 2> /dev/null
The page opened fine, no error shown – rather nothing has been shown. And no need to press enter.

Edit a text file on the console using Powershell

I'm trying to figure out the easiest way to edit text files in the console (PowerShell in my case). I'm using Windows 7 64 bit. It galls me that I can't just type edit filename.txt to edit a file. That used to work, but that's all changed. What are my options to view and edit text files within the windows console, and if you tell me to install and learn VIM I'm going to punch you in the face. :-)
Why not use notepad?
notepad.exe filename.txt
The old edit.com works in PowerShell (at least on my box: Windows 7 Pro x86) but in x64 it doesn't work due to its 16bit architecture.
You can take a look at this easy editor.
Kinesics Text Editor.
It's super fast and handles large text files, though minimal in features. There's a GUI version and console version (k.exe) included. Should work the same on linux.
Example: In my test it took 7 seconds to open a 500mb disk image.
While risking you punching me, I guess you are stuck with the solution you mentioned. Have a look at this posting on SuperUser:
Which are the non-x text editors in Powershell?
Also, there is a nano version for windows:
Nano Editor
I'll duck and cover now, hopefully someone will have a more sufficient answer.
Bit of a resurrect but for anyone else coming to this question, take a look at the Micro editor. It's a small standalone EXE with no dependencies and with native Windows 32\64 versions. Works well in both PowerShell and CMD.EXE.
I agree with Sven Plath. Nano is a great alternative. If you have Chocolatey or scoop, you can install nano by typing the following in Powershell:
PS C:\dev\> choco install nano
# --OR--
PS C:\dev\> scoop install nano
Then, to edit somefile.txt enter:
PS C:\dev\> nano somefile.txt
It's pretty neat!
Edit:
Nano works well on my Windows 10 box but takes incredibly long to load the first time on my Windows 7 machine. That made me switch to vim (vi) on my Win 7 laptop
PS C:\dev\> choco install vim
PS C:\dev\> vim $profile
Add a line in the powershell profile to Set-Alias (sal)
sal vi vim
Esc - : - x - Enter :-)
If you use Windows container and you want change any file, you can get and use Vim in Powershell console easily.
To shelled to the Windows Docker container with PowerShell:
docker exec -it <name> powershell
First get Chocolatey package manager
Invoke-WebRequest https://chocolatey.org/install.ps1 -UseBasicParsing | Invoke-Expression;
Install Vim
choco install vim
Refresh ENVIRONMENTAL VARIABLE
You can just exit and shell back to the container
Go to file location and Vim it vim file.txt
You could install Far Manager (a great OFM, by the way) and call its editor like that:
Far /e filename.txt
You can install nano in powershell via choco - It's a low friction way to get text editing capabilities into powershell:
Install Choco
Set-ExecutionPolicy Bypass -Scope Process -Force; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))
Install Nano
choco install nano
Profit
nano myfile.txt
Best part is it becomes part of the path, and stays working across reboots etc :)
install vim from online, and then you can just do:
vim "filename" to edit that file
I'm thinking you could just use notepad, like this:
notepad myfile.extension
It should open in notepad.
I am a retired engineer who grew up with DOS, Fortran, IBM360, etc. in the 60's and like others on this blog I sorely miss the loss of a command line editor in 64-bit Windows. After spending a week browsing the internet and testing editors, I wanted to share my best solution: Notepad++. It's a far cry from DOS EDIT, but there are some side benefits. It is unfortunately a screen editor, requires a mouse, and is consequently slow. On the other hand it is a decent Fortran source editor and has row and column numbers displayed. It can keep multiple tabs for files being edited and even remembers where the cursor was last. I of course keep typing keyboard codes (50 years of habit) but surprisingly at least some of them work. Maybe not a documented feature. I renamed the editor to EDIT.EXE, set up a path to it, and invoke it from command line. It's not too bad. I'm living with it. BTW be careful not to use the tab key in Fortran source. Puts an ASCII 6 in the text. It's invisible and gFortran, at least, can't deal with it. Notepad++ probably has a lot of features that I don't have time to mess with.
Not sure if this will benefit anybody, but if you are using Azure CloudShell PowerShell you can just type:
code file.txt
And Visual Studio code will popup with the file to be edit, pretty great.
Well there are thousand ways to edit a Text file on windows 7.
Usually people Install Sublime , Atom and Notepad++ as an editor.
For command line , I think the Basic Edit command (by the way which does not work on 64 bit computers) is good;Alternatively I find type con > filename as a very Applaudable method.If windows is newly installed and One wants to avoid Notepad. This might be it!!
The perfect usage of Type as an editor :)

I had to do some debugging on a Windows Nano docker image and needed to edit the content of a file, who would have guessed it was so difficult.
I used a combination of Get-Content and Set-Content and base 64 encoding/decoding to update files. For instance
Editing foo.txt
PS C:\app> Set-Content foo.txt "Hello World"
PS C:\app> Get-Content foo.txt
Hello World
PS C:\app> [System.Text.Encoding]::UTF8.GetString([System.Convert]::FromBase64String("TXkgbmV3IG11bHRpDQpsaW5lIGRvY3VtZW50DQp3aXRoIGFsbCBraW5kcyBvZiBmdW4gc3R1ZmYNCiFAIyVeJSQmXiYoJiopIUAjIw0KLi4ud29ybGQ=")) | Set-Content foo.txt
PS C:\app> Get-Content foo.txt
My new multi
line document
with all kinds of fun stuff
!##%^%$&^&(&*)!###
...world
PS C:\app>
The trick is piping the base 64 decoded string to Set-Content
[System.Text.Encoding]::UTF8.GetString([System.Convert]::FromBase64String("...")) | Set-Content foo.txt
Its no vim but I can update files, for what its worth.
In linux i'm a fun of Nano or vim, i used to use nano and now vim, and they are really good choices. There is a version for windows. Here is the link https://nano-editor.org/dist/win32-support/
However more often we need to open the file in question, from the command line as quick as possible, to not loose time. We can use notepad.exe, we can use notepad++, and yea, we can use sublim text. I think there is no greater then a lightweight, Too powerful editor. Sublime text here. for the thing, we just don't want to get out of the command line, or we want to use the command line to be fast. and yea. We can use sublime text for that. it contain a command line that let you quickly open a file in sublime text. Also there is different options arguments you can make use of. Here how you do it.
First you need to know that there is subl.exe. a command line interface for sublim.
1-> first we create a batch file. the content is
#ECHO OFF
"C:\Program Files\Sublime Text 3\subl.exe" %*
We can save that wherever we want. I preferred to create a directory on sublime text installation directory. And saved there the batch file we come to write and create.
(Remark: change the path above fallowing your installation).
2-> we add that folder to the path system environment variable. and that's it.
or from system config (windows 7/8/10)
then:
then:
then we copy the path:
then we add that to the path variable:
too quick!
launch a new cmd and now you've got subl command working well!
to open a file you need just to use subl command as fellow:
subl myfileToOpen.txt
you can also use one of the options arguments (type --help to see them as in the image above).
Also note that you can apply the same method with mostly any editor of your choice.
You can do the following:
bash -c "nano index.html"
The command above opens the index.html file with the nano editor within Powershell.
Alternatively, you can use the vim editor with the following command
bash -c "vi index.html"
If you have windows subsystem for linux (wsl), you will find the following command very useful:
bash -c "vi filename.txt"
Sadly powershell doesn't come with a built in console-text editor.
You can redirect standard input for simple oneliners like so:
# write text and overwrite the file with that text
"my text that will appear in the file" > file.txt
For anything more complicated you will need a package manager Chocolatey
Set-ExecutionPolicy Bypass -Scope Process -Force; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))
and install any of the following editors:
Nano
choco install nano
Issues
Very laggy on windows
Problems with arrow control
Vim
choco install vim
Issues
No major issues just remember esc + :!qa will exit vim

Screen and Cygwin: no tab completion?

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)

getting vi and rxvt to work in cygwin

I am trying to use rxvt on my cygwin w win XP but the terminal appears and disappears. What could be wrong? This is true for all except rxvt-native . I have tried a few commands found online but with no success. I include 2 I have tried:
start C:\cygwin\bin\rxvt.exe -sb -sl 3000 -fg gray -bg black -fn "Lucida Console-14" -e /bin/bash --login -i
.
path C:\cygwin\bin;%path%
ssh-agent rxvt -e bash --login -i
Another problem I am facing is trying to get vi to work in my cygwin bash shell. Setting term to xterm or vt100 does not work. Hitting enter, I see a string 78 or some other issue pops up. I have never modified my .inputrc.
My main issue was trying to get vi to work properly. I just found out that if I run
/etc/postinstall/terminfo.sh.done , I can now navigate properly in vi. The 78 (newline) M still appears but at least I can navigate in vi.
Feb 25 - This problem went away after a few windows updates. Would it make sense to ANSWER my question on the basis that this is longer reproducible?
Can't answer the first question, but have you tried invoking rxvt from its shortcut in the Cygwin folder of the start menu?
Regarding the second question, the TERM variable tells applications what terminal they're running in, so if you set it to 'xterm' while running in the Cygwin console (where normally TERM=cygwin), they'll be sending xterm control sequences that the Cygwin console doesn't understand. So basically: don't do that!
Btw, you might also be interested in Cygwin's mintty package, which is another terminal that doesn't need an X server. Installing it also creates a start menu shortcut in the Cygwin folder.
I would assume you need an X server running.
You could install Cygwin/X
One thing which may not have been clear was that the whole exercise was to get vi to work. vim did not work either at that time. But after some windows update, the problem went away. Closing it...
