(Note: I have plenty of python and unix shell experience, but fairly new to ipython -- using 7.5)
I'm trying to replicate a UNIX shell function that I use all the time, so that it works in the ipython shell.
The requirement is that I want to type something like to myproj, and then have ipython process the resulting text by doing a cd to the directory that comes back from to. (This is a quick-directory-change utility I use in unix)
The way it works in unix is that a shell function invokes an external command, that command prints its result to stdout, and the shell function then invokes the internal cd to the target dir.
I've been trying to wrap my head around %magic and macros and aliases in ipython, but so far I don't see how to get this done. Any ideas?
Is it possible to start a command prompt from perl script using Win32::Process::Create package?
I am trying to start DOORS from perl script. The executable is present in C:\Program Files\DOORS\bin\runDOORS9.rck.
I need to start the runDOORS9.rck with the argument COL9 to change the Database.
Try the good old system() function. On Windows it would use the cmd.exe, the system shell, to execute the command.
Since what you try to launch doesn't seem to be an .exe file, potentially you would have to use the start command of the cmd.exe.
For example:
system(qq{start "" "C:\Program Files\DOORS\bin\runDOORS9.rck" COL9});
(The first "" is required due to quirky argument parsing of the Window's shell commands. See help start for more information.)
I am debugging a windows process that crashes if the execution stops for even a few milliseconds. (I don't know how many exactly, but it is definitely less than the time taken by my reflexes to resume the process.)
I know I can launch a windbg session via the command prompt by typing in windbg -p PID which brings up the GUI. But can I then further pass it windbg commands via the command prompt, such as bm *foo!bar* ".frame;gc";g".
Because If I can pass it these commands I can write these down in a .bat file and just run it. There would at least be no delay due to entering (or even copy-pasting) the commands.
Use the -c parameter to pass them:
windbg -p PID -c "bm *foo!bar* .frame;gc;g"
According to the help (found by running windbg /?):
-c "command"
Specifies the initial debugger command to run at start-up. This command must be enclosed in quotation marks. Multiple commands can be separated with semicolons. (If you have a long command list, it may be easier to put them in a script and then use the -c option with the $<, $><, $><, $$>< (Run Script File) command.)
If you are starting a debugging client, this command must be intended for the debugging server. Client-specific commands, such as .lsrcpath, are not allowed.
You may need to play around with the quotes...
Edit: Based on this answer, you might be better off putting the commands into a script file to deal with the quotes:
script.txt (I think this is what you want):
bm *foo!bar* ".frame;gc"
g
Then in your batch file:
windbg -p PID -c "$<full_path_to_script_txt"
Making my PHP Command line application support Linux and Windows. Currently it has this code below to work from command line on Linux/unix
How can I make it work on Windows? I lan on having a setting to determine if the sytem is Linux or Windows and using the correct commands based on that but I do not know how to make these function below work in Windows
exec() is a PHP function to run stuff through the command line
exec("rm -f $dest_file", $var);
exec("mv $quant_file {$this->tmp_path}/{$src_filename}-quant.png");
You could test which platform you're on using the PHP_OS constant and run commands accordingly.
I would, however, suggest that you use the PHP provided filesystem functions (if possible).
Here are some links:

I have script lets say:
C:\foo.bsh
I want to be able to run this command via the windows run command:
Start -> Run
Windows Key + R
and type something small like 'foo' and hitting return.
However, I do not want a cmd prompt to be visible. This script does some preprocessing for an IDE. I do not want the cmd prompt to be open for the lifetime of the IDE process.
I have tried:
1) Creating a bat file with the following contents:
c:\cygwin\bin\bash --login "C:\foo.bsh" (this fails because it keeps a cmd open)
2) Converting the above bat file to an exe using bat_2_exe_converter (does not make the cmd silent)
thoughts?
EDIT: The solution so far suggests something to type from an actual cygwin shell. I am trying to get a faster solution by having something short I can type in the Windows run command. Also, the nohup command; exit doesn't automatically kill the box - however I can manually kill it without killing the IDE process. The run command accepts shortcuts (.lnk's), bat's, exe's.
Try the run.exe command of cygwin. It is a big install, a complete unix environment for your Windows machine. Suppose you installed it at c:\cygwin\.
No mystery, just run c:\cygwin\bin\run.exe <your command here> and you will have your no dos window execution.
You can run it from any DOS window (run cmd.exe from the start menu). You don't need to run it from cygwin.
To make it easier, append C:\cygwin\bin to your %PATH% env var (My Computer → Properties → Advanced → Environment Variables) (Kudos to Felipe Alvarez comment).
Now you can just type
c:\cygwin\bin\run.exe "C:\foo.bsh"
You must create a link in your Start Menu with this command so will be able to run it with Win-R.
Here is the man page of the runcommand:
$ man run
RUN(1) run 1.3.0 RUN(1)
NAME
run - start programs with hidden console window
SYNOPSIS
run [ -p path ] command [ -wait ] arguments
runcommand [ -p path ] [ -wait ] arguments
DESCRIPTION
Windows programs are either GUI programs or console programs. When
started console programs will either attach to an existing console
or create a new one. GUI programs can never attach to an exiting con‐
sole. There is no way to attach to an existing console but hide it if
started as GUI program.
run will do this for you. It works as intermediate and starts a pro‐
gram but makes the console window hidden.
With -p path you can add path to the PATH environment variable.
Issuing -wait as first program argument will make run wait for program
completition, otherwise it returns immediately.
The second variant is for creating wrappers. If the executable is
named runcommand (eg runemacs), run will try to start the program (eg
emacs).
EXAMPLES
run -p /usr/X11R6/bin xterm
run emacs -wait
runemacs -wait
run make -wait

You can use either...
c:\cygwin\bin\bash -l /path/to/script_to_interpret.sh
...or...
c:\cygwin\bin\bash -l -c /path/to/executable_script.sh
Note: the -l flag tell bash to "act as if it had been directly invoked by login" and use Bash Startup Files. This is important in that it sets your $PATH and other things you rely on when you launch a cygwin terminal. If you don't include -l or --login you will get "command not found" when you try to call anything except of a bash builtin.
The difference between the 2 is like the difference between doing...
bash script_to_interpret.sh
...and...
./executable_script.sh
...in *nix. The former interprets the script using bash. The latter executes the script (only if it has chmod +x executable_script.sh) and interprets it according to its "shebang" line. The latter method is also what you want to do if your executable is not a script at all, like a *nix binary compiled from source.)
It has been bugging me for a while I couldn't find the solution for this, but I finally got the right mix together.
You can simply do the following if you have cygwin on your PATH:
run bash test.js
If cygwin is not on your path, you can do this:
c:\cygwin\bin\run.exe -p /bin bash test.js
If you are looking for more control over the created window (maximize, etc) it looks like you can use cygstart also.

As the terminal can't close while your script is still running, try the command:
"nohup C:\foo.bsh; exit"
This way your script will be backgrounded and detached from the terminal, and it should exit quickly so the terminal goes away. I think that the window may still 'flash' with this approach, but the results should be better than what you're getting.
I'm running Cygwin64 and the xwin server link points to:
C:\cygwin64\bin\run.exe /usr/bin/bash.exe -l -c /usr/bin/startxwin.exe
This creates an icon AND a notification on the taskbar. I don't like that. The icon is rather useless, the notification has all your menu options from .XWinrc.
So... I wrote a .vbs script to silently run this command and make the icon go away:
Set objShell = CreateObject("WScript.Shell")
objShell.Run("C:\cygwin64\bin\run.exe /usr/bin/bash.exe -l -c /usr/bin/startxwin.exe"), 0
Another imperfect possibility is to run the script via a shortcut and set the shortcut's Run option to "minimized".
Go to the directory where you have installed cygwin(on my machine it is c:/cygwin64/bin)
Once there simply type "bash.exe"
