I need to launch xterm using system call in a perl script and follow by executing a simple script to kick start a tool to run. The problem is that, in the newly launched xterm, it has no setup at all. The reason i want to use simbuild command to allow the newly launched xterm with all the setup required by the tool so that i can easily kick start the tool to run.
system("xterm", "-hold", "-e", "sh", "-c", $script);
NOTE: $script contains simple setenv and a command to kick start a tool.
This is the simbuild command that I want to use, with passing several arguments
simbuild -dut usbx -1c -CUST MTLM_SA -1c- -ace "xterm"
Please advise how this can be done through system call in Perl. Thanks!

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"
I cannot run PowerShell.exe interactively in a Cygwin rxvt or mintty terminal. Seems any session using a /dev/tty? or /dev/pts? pseudo terminal device. An instance using the junky windows console device /dev/console or /dev/cons? will work.
cygstart /bin/bash -li
launches the console version in the cruddy Windows Command Prompt which is the only place I can get an interactive PowerShell.
Works. Rxvt doesnt:
Nor does mintty:
I've tried all the echo -e | powershell.exe and powershell.exe </dev/null
I'm assuming when I see answers on Stackoverflow on this they are using Console's ... or am I missing something?
Why I cannot run PowerShell 2 from Cygwin? seems to run fine, just gets powershell v3 when he wants v2 ... wish I had that problem.
I've developed a powershell wrapper to call powershell scripts and commands from a Cygwin terminal session but cannot get the interactive option to work (if you give the wrapper no script or commands then you want to go interactive). see https://bitbucket.org/jbianchi/powershell/wiki/ for info on the wrapper script. It works for most powershell.exe calls and even acts like a "she-bang" if used in the first line of the ps1 script.
Today, typing powershell at a Cygwin bash prompt just works.
If you need to run powershell inside cygwin/babun, follow https://code.google.com/p/mintty/issues/detail?id=56#c64 . Bascilly, downloard or compile https://github.com/rprichard/winpty, copy it to your $PATH and then run
console.exe powershell
This also works with batch scripts that invoke powershell inside.
The solution I've found is to use http://sergeybelous.com/ (main site) Proxy32 proxywinconsole.exe program. If this program is in the path, my poweshell.bash wrapper will call it which will let you work interactively with PowerShell.
First Install cygwin in your system.
After that type bash on powershell terminal and you can access cygwin terminal.
PS C:\Users\username\1and1> bash
username#LWMT-14R25Q2:/mnt/c/Users/username/1and1$
I'm afraid I can't answer your question, but maybe I can help you a little further on your way with this:
I believe this is related to this issue, as discussed on the MinTTY Issue #56.
It goes into great detail as to how common cmd.exe shell applications work and interact, so much as they detail how common unix applications using their TTY abstraction layer work differently than Windows command line applications.
Script for running powershell on Cygwin minty:
blahblah#blahblahbin $ cat pwrshl
#!/usr/bin/bash if [[ ! -f "$1" ]] then
echo "Usage: $0 <PowerShellScriptFile>"
exit fi
echo "\n" | powershell -Command "& {$(<$1)}"
using Expect perl module, i have written script that uses ssh command on local host machine to emulate a terminal. so consider the below scenario, i have a perl script (say script.pl) which uses expect module, and have two commands of this type
$ssh = Expect->spawn("ssh -Y $loginname\#$systemname")
so the problem here is...i am using a terminal to execute script.pl and my code has two spawn commands. I noticed that two spawn commands are started within the terminal used to execute script.pl. But i want two new terminals for two spawn commands. So here there should be three terminals one for script.pl, two for each spawn commands in the script.pl.
Is there any way of achieving two new terminals from single perl script using Expect??
"Is there any way of achieving two new terminals from single perl script using Expect??"
Sure. But a terminal is an application like anything. You have to invoke it explicitly; all you are spawning is ssh. Terminal applications are heterogeneous, so you need to figure out what terminal application is running on your system and how to get it to launch an application at start-up. Eg, for the Xfce terminal something like:
$ssh = Expect->spawn("Terminal -e \"ssh -Y $loginname\#$systemname\"");
should work. Or perhaps better:
$ssh = Expect->spawn("Terminal", ("-e", "ssh -Y $loginname\#$systemname"));
However, your terminal is probably not the Xfce terminal. If you are on Windows, I believe it is cmd. On Linux it depends upon what is installed; if you are using a distro default it will be the terminal that came with the DE -- gnome-terminal for GNOME, konsole for KDE, etc.
It might make more sense, however, if you automate launching the terminals some other way and have them execute a script using expect/ssh at start-up.
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"
