I have a small utility script called clear.bat that does some housekeeping work on my sources.
It is a .bat file so that I could easily double-click it in Windows Explorer.
Sometimes, I find it more handy to execute it from my Git bash (msysgit, if this matters).
To do this, I type
cmd
clear.bat
exit
cmd turns my Git bash into a normal cmd window where I could easily execute my batch. When I type exit, the cmd environment is terminated and I'm back in my Git bash.
Could this be achieved in an easier way?
I tried cmd /C clean.bat since the docs say
Syntax
CMD [charset] [options]
CMD [charset] [options] [/c Command]
CMD [charset] [options] [/k Command]
Options
/C Run Command and then terminate
/K Run Command and then return to the CMD prompt.
This is useful for testing, to examine variables
Edit:
Just noticed that the post is broken.
What I want is to execute clean.bat from within the Git bash without having to type the three commands above (cmd, clear.bat, exit). I just want to execute the .bat file from within my Git bash. Obvious way would be to create a separate .sh file that does the same work but this will lead to double code.
Edit 2:
When I execute cmd /C clean.bat, the Git bash turns into a plain CMD environment and only displays the prompt. The file clean.bat does not get executed. It's the same as if I just type cmd.
Also, adding a /debug switch does literally nothing. Seems like only cmd gets evaluated and all further parameters are getting ignored.
After playing around a bit more, I found the solution myself:
cmd "/C clean.bat"
does the trick. But I got no clue, why...
./clear.bat will do the trick.
The Git for Windows (msysGit has been superseded by Git for Windows1) FAQ says you have 3 options:
Run programs that have problems using the winpty utility. This allows you to keep using the nicer mintty terminal, but can become unwieldy if you need the workaround for many programs.
Modify the shortcut for Git Bash to run bash directly without mintty so it uses the default console host and configure it for "Quick Edit", reasonable size and scroll-back and suitable unicode font. You'll still have to live with the other quirks of console host.
Install and use ConEmu.
At some point, Git for windows added support for the MSYS_NO_PATHCONV environment variable, so in addition to #eckes and #AlikElzin-kilaka solutions, you can also
MSYS_NO_PATHCONV=1 cmd /c clean.bat
In general, I prefer this solution, as it allows the code to be the closest to resembling normal bash, and there are many ways to export MSYS_NO_PATHCONV depending on your preferred situation.
Note: Git for Window's bash does not support the MSYS2 environment variable MSYS2_ARG_CONV_EXCL
The other solutions
The weird quoting solution
Why does cmd "/c clean.bat" not create other errors?
It turns out argument parsing in windows does not follow the same universal rules as it does in *nix. Instead, in windows the arguments are parsed differently based on the runtime you compile against. Basically in windows, the command line arguments are passed in as "one string" and then parsed by the runtime.
See here(archive) for more explanation than you could ever want.
E.g. cmd parses arguments differently then wscript.exe
In the end, you can hopefully find something that works with this method, and it is the most "window-esque" of the three solutions
The // method
This is pretty well explained here and simple to use, but adds an extra / which does not help readability
I like start clean, it opens a new window with cmd. This method has some benefits:
cmd.exe gets a native console
the new console has a native windows character encoding (e.g. cp1251 vs utf8)
This will work and it frees the terminal too
nohup ./nucleus.bat &
less nohup.out

In conemu using cmd I can edit the prompt nice and easy in the CmdInit.cmd file - I do this because I don't like the prompt spread over two lines.
However I can't seem to do the same trick when I select the startup in settings to be bash::Cygwin.
I see that the CmdInit.cmd is dos commands, so I could create a startup.sh? not sure how I invoke it.
Also the PROMT variable does not seem to exist in the bash mode - even though there is a very long two-line prompt. How can I change it? Where are the defaults even taken from?
I'm trying to run gitk on Windows but the console gives me:
'gitk' is not recognized as an internal or external command,
operable program or batch file.
But then, I can do
> where gitk
C:\Program Files (x86)\Git\bin\gitk
How comes?
UPDATE: Stealing the OP's comment:
Thanks for a (lengthy) explanation, the easiest fix for me was to move from the old msysGit (1.9.5) version to the newer "Git for Windows" builds which has a proper Windows wrapper for gitk.
gitk, unlike most git commands, is a shell script that invokes Tcl.
If you examine the gitk executable file itself, its first few lines are:
#!/bin/sh
# Tcl ignores the next line -*- tcl -*- \
exec wish "$0" -- "$#"
(At least that's what it looks like on my Linux system; the Windows installer for gitk might change that.)
On a Unix-like system, that first line, known as a "shebang", tells the system to invoke /bin/sh to execute the file rather than executing it directly.
The third line executes the wish command, which executes the script as a Tcl script.
If you have Tcl installed on your Windows system, you should be able to run gitk as a Tcl script using something like this:
C:\> tclsh "C:\Program Files (x86)\Git\bin\gitk"
(Disclaimer: I have not tried this.)
You might also be able to change the command's name from gitk to gitk.tcl and set up a file association in Windows so it will be invoked correctly. (I'm a little surprised that the Windows git installer didn't do this for you.)
More information on running Tcl scripts on Windows can be found here.
And this question discusses invoking gitk on Windows from the context menu rather than from the command line.

Is there a way to suppress showing the command window when running a console application on Windows XP?
Details: I am calling a (console-based) program from Vim. I would like to avoid the command window being shown every time I do this.
Try start /B <program name> to start the program without a new window.
Did you try shell.vim?
The xolox#shell#execute() function
This function enables other Vim
plug-ins to execute external commands
in the background (i.e.
asynchronously) without opening a
command prompt window on Windows.
i can't believe no one has suggested simply using :silent
for example, I have the following in my .vimrc (gvim on Win7)
"open windows explorer to the directory of the current file
:map <leader>ex :silent !Explorer %:p:h<CR>
When I didn’t want to see the output of external commands called from the Vim command line, I would prepend them with :silent. However, this results in a command window momentarily flashing on screen when running GVim under MS Windows. After a short while, I got annoyed by this behaviour so I researched alternative solutions (which is how I came across this question).
The best solution I came up with was to use Vim’s inbuilt system function which runs shell commands without opening an external command window. While the output of the shell command is not printed, its exit status is conveniently available via v:shell_error. It also has the advantage that it’s portable across (all) platforms.
Example (the echo statement should print 0 if C:\Windows exists):
call system("dir c:\windows")
echo v:shell_error
You could maybe use some autohotkey script of this kind:
Loop {
WinWait, my command window title
WinHide
}
I was trying to use git-bash as my shell from vim on Windows but having the command prompt open whenever a command was run, as you described. My eventual solution was to install the plugin xolox/vim-shell and add the following snippet to .vimrc:
if has('win32')
set shell=bash\ -c
set shellcmdflag=
set shellxquote='
set shellquote=
set shellredir=>
set noshelltemp "This prevents an external window from opening.
endif
This utility will also do the job:

Im trying to automatically run a script using Cygwin via CMD. I basically created a BAT file that goes to the directory and executes an .SH file. SH files are accosiated with Cygwin, and I tried something like "cygwin update.sh" in the command line. But all it really does is open Cygwin. I want Cygwin to automatically run the script file. Is there any easy way to do this, I've been trying to find but can't. Thank you!
You'll want to call the shell script with a particular shell, e.g. bash.
When having Cygwin open, call which bash to figure out where the binary is located. Cygwin also comes with tools that can convert paths between Cygwin and Win32 form, which is pretty helpful in cases like yours.
There is one other thing that may work, depending on your setup. There is an environment variable named PATHEXT which declares file extensions that are deemed "executable" by CMD. This can be used to your advantage, if Windows is configured so that the shell's "open" verb executes the correct shell for the file extension .sh (in your case).
Good luck.
From Cygwin Terminal, read man mintty. Try something like the following from a Windows Command Prompt:
c:\cygwin\bin\mintty --hold always --exec /cygdrive/c/path/to/bash/script.sh
I also found this!

I didn't quite understand it at first, but then it worked as I wanted it. Just if anyone knows, is there a way to make the script run without the CMD window open?? Thanks
