I have a shell script that is used both on Windows/Cygwin and Mac and Linux. It needs slightly different variables for each versions.
How can a shell/bash script detect whether it is running in Cygwin, on a Mac or in Linux?

How can I create a Cygwin shortcut that will open Cygwin at a specific folder? This would avoid me having to type
cd /cygdrive/c/Users/Tom/Desktop/
each time I launch Cygwin.

I need an offline installer with most of the utilities commonly needed. Somehow the default installer confuses me with all its package selection. I installed Cygwin but I can't find the diff
utility after the installation.

This question already has an answer here:
I just installed Cygwin, and it looks like the home directory in the bash prompt is on my Z: drive. That's not where I want it.
How can I change this?

cyg-apt: downloading: http://cygwin.mirrors.pair.com/setup-2.ini
cyg-apt: bad URL http://cygwin.mirrors.pair.com/setup-2.ini, exiting.

I'm trying to run a bash script in Cygwin.
I get Must run as root, i.e. sudo ./scriptname
errors.
chmod 777 scriptname
does nothing to help.
I've looked for ways to imitate sudo on Cygwin, to add a root user, since calling "su" renders the error su: user root does not exist
, anything useful, and have found nothing.
Anyone have any suggestions?

I want to make my C++ project cross platform, and I'm considering using Cygwin/MinGW.
But what is the difference between them ?
Another question is whether I will be able to run the binary on a system without Cygwin/MinGW ?

I've tried msysGit and Git on Cygwin. Both work just fine in and of themselves and both run gitk and git-gui perfectly.
Now how the heck do I configure a mergetool? (Vimdiff works on Cygwin, but preferrably I would like something a little more user-friendly for some of our more. Windows-loving coworkers.)

What would be the best way to write Objective-C on the Windows platform?
Cygwin and gcc? Is there a way I can somehow integrate this into Visual Studio?
Along those lines - are there any suggestions as to how to link in and use the Windows SDK for something like this. Its a different beast but I know I can write assembly and link in the Windows DLLs giving me accessibility to those calls but I don't know how to do this without googling and getting piecemeal directions.
Is anyone aware of a good online or book resource to do or explain these kinds of things?

I installed Cygwin, choosing a fairly minimal set of packages.
In a terminal, I tried to do 'clear' to clear the terminal, but I get
bash: clear: command not found
How do I get this to work?

I'm stuck behind a firewall so have to use HTTPS to access my GitHub repository. I'm using cygwin 1.7.7 on Windows XP.
I've tried setting the remote to https://username@github.com/username/ExcelANT.git
, but pushing prompts for a password, but doesn't do anything once I've entered it.
https://username:<password>github.com/username/ExcelANT.git
and cloning the empty repo from scratch but each time it gives me the same error
error: SSL certificate problem, verify that the CA cert is OK. Details:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed while accessing https://github.com/username/ExcelANT.git/info/refs
Turning on GIT_CURL_VERBOSE=1
gives me

fatal: HTTP request failed
Is this a problem with my firewall, cygwin or what?
I hadn't set the HTTP proxy in the Git config, however it's an ISA server that needs NTLM authentication, not basic, so unless anyone knows how to force git to use NTLM, I'm scuppered.

Git Extensions: Everything was working fine until yesterday.
But suddenly I am get this error when I try to pull some repositories using git extensions
C:\Program Files\Git\bin\git.exe pull --progress "origin"
Done
0 [main] us 0 init_cheap: VirtualAlloc pointer is null, Win32 error 487
AllocationBase 0x0, BaseAddress 0x68560000, RegionSize 0x390000, State 0x10000
C:\Program Files\Git\bin\sh.exe: *** Couldn't reserve space for cygwin's heap, Win32 error 0
It is happening for all the repositories which I have cloned.
But, my git bash is working fine.
I don't have any idea what is going on. Any idea as to why this is happening?

I'm trying to install PyQt4 so I can mess around with it. The installation guide said I had to install sip. The last step to installing sip is to use the make install
command. Windows doesn't have that, so I looked it up and everything I saw said to install cygwin. So I did. But...sip is in C:\Python31\sip.
Can I run this from the cygwin command? If so...how would I do that?
or...
Can I run this from the normal windows command prompt? If so...how
would I go about that?
