I wish to create log of function entry and exit for my code. I am using the following command in WinDbg-
Function name and the return value
bm <module_name>!* "kcL1;.echotime;gu;r eax;.echotime;gc;"
Now I wish to do this for all the modules of the function but I don't want to write the code again for each module. Is there some way to specify bm to read module names from a file which I create using "lm" and set breakpoint for each module or something even more simple.
Also, how can I specify bm to not print the output on the screen? I am using a log file.
Sometimes I don't see the time for call exit. What can be the reason for this? How can I correct it?
you can use !for_each_module
You will not see call exit time if another breakpoint is hit (in another thread, or if the funciton calls other functions that have breakpoints)

In my personal PowerShell profile that loads whenever I start PowerShell, I want to include a set of functions by calling a function.
So I want to do something like this:
function loadMyFunctions{
. \MyFunctions.ps1
}
Now, in MyFunctions.ps1 I have a function:
function bobtest{
write-host "My name is Bob Newhart."
}
I am able to load the script MyFunctions.ps1, but after that is loaded I am not able to call bobtest in the console - I get the error message The term bobtest is not recognized...
However, if I just load the script outside the function then that script is loaded and I can call bobtest normally - but that means that I can't just not load MyFunctions when the profile is loaded - I have to load MyFunctions and cannot choose.
You see, I want to load the other functions on demand and not have them available until I choose.
Is there another way to do this or can it even be done?
Have a look at this page, How to Create PowerShell Modules and Manifests.
This will enable you to create a module which will have all your custom functions! Then inside of your loadMyFunctions cmdlet add Import-Module NewModuleName.
This will enable you to use your cmdlets.
Hope this Helps,

Best way is to use modules. But still if you want to get in some different ways , then you can try with your approach.
See the below screenshots which I have performed.
I have a function addition which simply does addition and I saved it as funct1.ps1
Now I am calling the same function from another function of the other script just using dot source without using as module and it results me properly.
Funct1.ps1
Triggered the function from another function in another script .
Hope it helps...!!!
PHP has the nifty include() function to bring in external files into the main script. Is this possible in Octave? I tried using load() but I keep getting an error: error: load: unable to determine the file format of 't_whse.m' which makes me think this is the wrong way to do this or that it's actually not possible in Octave.
You don't need to call load, as load is reserved for loading data from a file. Instead, you just want to call the script by name. This will (if it's actually a script) execute the script and make any variables that were defined in that script accessible to the calling script.
script1.m
disp('Beginning of script1');
script2;
fprintf('Value = %d\n', value)
disp('End of script1')
script2.m
disp('Beginning of script2');
value = 2;
disp('End of script 2');
I've been trying to use raster calculation in ipython for a tif file I have uploaded, but I'm unable to find the whole code for the function. I keep finding examples such as below, but am unsure how to use this.
gdal_calc.py -A input.tif --outfile=result.tif --calc="A*(A>0)" --NoDataValue=0
I then tried another process by assigning sections, however this still doesn't work (code below)
a = '/iPythonData/cstone/prec_7.tif'
outfile = '/iPythonData/cstone/prec_result.tif'
expr = 'A<125'
gdal_calc.py -A=a --outfile=outfile --calc='expr' --NoDataValue=0
It keeps coming up with can't assign to operator. Can someone please help with the whole code.
Looking at the source code for gdal_calc.py, the file is only about 300 lines. Here is a link to that file.

The punchline is that they just create an OptionParser object in main and pass it to the doit() method (Line 63). You could generate the same OptionParser instance based on the same arguments you pass to it via the command-line and call their doit method directly.
That said, a system call is perfectly valid per #thomas-k. This is only if you really want to stay in the Python environment.
I often call the same commands in MongoDb command shell, for example :
db.user().find().pretty();
How would you store and call back this command ?
Ideally converting it to something like this :
db.findp( 'user' );
I believe this is NOT what your looking for, now that I read your question again: http://docs.mongodb.org/manual/applications/server-side-javascript/
Instead you are looking to modify the console in such a manner to make your life easier.
I should note, right now, that there is actually an extension which can do this sort of auto-formatting for you made by 10gen: https://github.com/TylerBrock/mongo-hacker
However if you wish to modify the files behind MongoDBs console a little more then you will need to do some manual labour.
There is a rc script in your home directory called .mongorc.js. In this file you can place any custom code you like (as #Asya mentioned) and it will actually become a command within the console.
In you rc file you could place a function like:
DB.prototype.pfind = function(col){
return this[col].find().pretty();
};
Or you could write:
DBCollection.prototype.pfind = function(){
return this.find().pretty();
};
Then you should be able to do:
db.pfind('users');
Or with the second command:
db.users.pfind();
Of course this method is for Linux, I am unsure about Windows, however, Windows should have an rc type script somewhere I believe.
I have a problem with Net::Appliance::Session. I created a session, executed my command. After execution it prompts me some question (yes/no). I want to answer it but didn't find a way how to do it. Below you can see my trials:
$session->cmd($command);
$session->waitfor(Match=>'/.*yes*/');
$session->print("no");
$session->waitfor(Match=>'');
$session->print("y");
I don't know where is the problem. Accoding to CPAN documentations Net::Telnet have the method waitfor. But Session documentation tells that we can use waitfor(). Another thing said there is that the method "cmd" have a member Match which includes all the features of waitfor(). So I changed my code like below:
$session->cmd($command, Match=>'/.*yes*/');
$session->print("no");
Executing this reports below error:
Odd number of elements in hash assignment at
/usr/lib/perl5/vendor_perl/5.8.8/Net/Appliance/Session.pm line 245.
Is there any idea how can I do that? And why am I getting this error message?
Thanks in advance..

To handle more complicated interactions, for example commands which prompt for confirmation or optional parameters, you should use a Macro. These are set up in the phrasebook and issued via the $s->macro($name) method call. See the Phrasebook and Cookbook manual pages for further details.
So you set up a macro (scripted call and response) in a phrasebook, and then tell your session to use that macro.
