How do I display remote X clients with Cygwin/X?
Displaying remote X clients with Cygwin/X is identical to displaying remote X clients with any other X Server. It is recommended that you use the secure method of tunnelling the X connection over ssh .
Should I Turn Off the dB option in Cygwin DLL?
By leaving out the db option, we are telling the Cygwin DLL not to even try to do AD lookups. If your AD servers are slow, this local cache will speed things up. The downside is that you open yourself up to the stale cache problem: any time the AD databases change, your local cache will go out of date until you update the files manually.
How can I run a Cygwin service as my own user?
Workarounds include using public network share that does not require authentication (for non-critical files), providing your password to a net use command, or running the service as your own user with cygrunsrv-u (see /usr/share/doc/Cygwin/cygrunsrv.README for more information).
How to integrate Cygwin with Active Directory?
This is the old-fashioned method of making Cygwin integrate with AD, the only method available in releases before 1.7.34. To do this, run mkpasswd and mkgroup, then put the following into /etc/nsswitch.conf to make Cygwin treat these files as the only sources of user and group information:

Why is Cygwin used?
Cygwin offers users a Linux-like experience in a Windows environment. This capability helps developers migrate applications from Unix or Linux to Windows-based systems and makes it easier to support their applications running on the Windows platform. At the heart of the Cygwin collection of tools is the cygwin1.
Which is better Cygwin or MinGW?
MinGW is higher performance than Cygwin, but it's also 32-bit which may be a problem with your applications. There is a 64-bit environment similar to MinGW but it's a different project. MinGW-w64 is in all senses the successor to MinGW.
Does Cygwin have a GUI?
XLaunch is a GUI wizard for starting the Cygwin/X X server and a local or remote X client. These sessions can be saved and shared as . xlaunch files. XLaunch is included in the xlaunch package (installed by following the instructions in the Section called Installing Cygwin/X in Chapter 2).
Is Cygwin free for commercial use?
Red Hat has kept Cygwin as an open source application, free for public use. Commercial licenses are also available for purchase to users who want to redistribute applications that use the Cygwin library.
Is Cygwin Portable?
We shall use a portable version of Cygwin which is a UNIX-like environment and command-line interface. Cygwin can be installed on a portable USB thumb-drive or external hard-disk so that you can plug-and-play on any machine to do your work. We suggest a minimum disk space of 512MB for the installation.
Where are Cygwin files located?
The installation directory (by default, c:\cygwin) is the root of the Unix-like file system, which contains bin, etc, home, tmp, and usr directories as would be found on a GNU/Linux or other Unix system. Within home will be one or more subdirectories, each allocated to a Windows user.
Where are Cygwin files stored?
The Cygwin DLL supports user specific fstab files. These are stored in the directory /etc/fstab. d and the name of the file is the Cygwin username of the user, as it's created from the Windows account database or stored in the /etc/passwd file (see the section called “Mapping Windows accounts to POSIX accounts”).
Where is Cygwin home directory?
In a new installation of Cygwin, your home directory will be in C:/cygwin/home/
How do I know if Cygwin is installed?
Test Cygwin Open the command prompt of Windows either via the Program Menu or type cmd in the Start Search of Windows. Enter bash. If the bash prompt appears as shown in the picture below, it was successful. To end Cygwin enter exit, then enter exit again to end the command prompt.
What is the exec option in Cygwin?
The exec option is used to instruct Cygwin that the mounted file is "executable". If the exec option is used with a directory then all files in the directory are executable. This option allows other files to be marked as executable and avoids the overhead of opening each file to check for "magic" bytes.
What is the first field in Cygwin?
The first field describes the block special device or remote filesystem to be mounted. On Cygwin, this is the native Windows path which the mount point links in. As path separator you MUST use a slash. Usage of a backslash might lead to unexpected results. UNC paths (using slashes, not backslashes) are allowed. If the path contains spaces these can be escaped as '040'.
What is acl in cygwin?
acl - Cygwin uses the filesystem's access control lists (ACLs) to implement real POSIX permissions (default). This flag only affects filesystems supporting ACLs (NTFS, for instance) and is ignored otherwise. auto - Ignored. binary - Files default to binary mode (default). bind - Allows to remount part of the file hierarchy somewhere else. In contrast to other entries, the first field in the fstab line specifies an absolute POSIX path. This path is remounted to the POSIX path specified as the second path. The conversion to a Win32 path is done on the fly. Only the root path and paths preceding the bind entry in the fstab file are used to convert the POSIX path in the first field to an absolute Win32 path. Note that symlinks are ignored while performing this path conversion. cygexec - Treat all files below mount point as cygwin executables. dos - Always convert leading spaces and trailing dots and spaces to characters in the UNICODE private use area. This allows to use broken filesystems which only allow DOS filenames, even if they are not recognized as such by Cygwin. exec - Treat all files below mount point as executable. ihash - Always fake inode numbers rather than using the ones returned by the filesystem. This allows to use broken filesystems which don't return unambiguous inode numbers, even if they are not recognized as such by Cygwin. noacl - Cygwin ignores filesystem ACLs and only fakes a subset of permission bits based on the DOS readonly attribute. This behaviour is the default on FAT and FAT32. The flag is ignored on NFS filesystems. nosuid - No suid files are allowed (currently unimplemented). notexec - Treat all files below mount point as not executable. nouser - Mount is a system-wide mount. override - Force the override of an immutable mount point (currently "/"). posix=0 - Switch off case sensitivity for paths under this mount point (default for the cygdrive prefix). posix=1 - Switch on case sensitivity for paths under this mount point (default for all other mount points). sparse - Switch on support for sparse files. This option only makes sense on NTFS and then only if you really need sparse files. Cygwin does not try to create sparse files by default for performance reasons. text - Files default to CRLF text mode line endings. user - Mount is a user mount.
How many chars can a CWD path have?
The Windows subsystem only supports CWD paths of up to 258 chars. This restriction doesn't apply for Cygwin processes, at least not as long as they use the POSIX API (chdir, getcwd). This means, if a Cygwin process has a CWD using an absolute path longer than 258 characters, the Cygwin CWD and the Windows CWD differ.
Why does Cygwin use POSIX?
Because many programs written to run on UNIX systems assume the existence of a single unified POSIX file system structure, Cygwin maintains a special internal POSIX view of the Win32 file system that allows these programs to successfully run under Windows. Cygwin uses this mapping to translate from POSIX to Win32 paths as necessary.
What are the exceptions to cygdrive?
The only two exceptions are the file system types cygdrive and usertemp. The cygdrive type is used to set the cygdrive prefix. For a description of the cygdrive prefix see the section called “The cygdrive path prefix”, for a description of the usertemp file system type see the section called “The usertemp file system type”
Does Cygwin support POSIX?
The Cygwin DLL supports both POSIX- and Win32-style paths. Directory delimiters may be either forward slashes or backslashes. Paths using backslashes or starting with a drive letter are always handled as Win32 paths. POSIX paths must only use forward slashes as delimiter, otherwise they are treated as Win32 paths and file access might fail in surprising ways.
How to install Cygwin?
There is only one recommended way to install Cygwin, which is to use the Cygwin Setup program, a GUI installer named setup-x86_64.exe for 64 bit Windows, or setup-x86.exe for 32 bit Windows. It is flexible and easy to use. You can pick and choose the packages you wish to install, and update them individually. Full source code is available for all packages and tools. More information is available on using the Cygwin Setup program.
Where to find Cygwin documentation?
If you have installed Cygwin, you can find lots of documentation in /usr/share/doc/ . Some packages have Cygwin specific instructions in a file /usr/share/doc/Cygwin/package_name.README . In addition, many packages ship with standard documentation, which you can find in /usr/share/doc/package_name or by using the man or info tools. (Hint: use cygcheck -l package_name to list what man pages the package includes.) Some older packages still keep their documentation in /usr/doc/ instead of /usr/share/doc/ .
What is a Cygwin package?
The Cygwin distribution contains thousands of packages from the Open Source world including most GNU tools, many BSD tools, an X server and a full set of X applications. If you're a developer you will find tools, headers and libraries allowing to write Windows console or GUI applications that make use of significant parts of the POSIX API. Cygwin allows easy porting of many Unix programs without the need for extensive changes to the source code. This includes configuring and building most of the available GNU or BSD software, including the packages included with the Cygwin distribution themselves. They can be used from one of the provided Unix shells like bash, tcsh or zsh.
What is the prefix for a drive in Cygwin?
Cygwin has a builtin "cygdrive prefix" for drives that are not mounted. You can access any drive, say Z:, as '/cygdrive/z/'. In some applications (notably bash), you can use the familiar windows <drive>:/path/, using posix forward-slashes ('/') instead of Windows backward-slashes (''). (But see the warning below!)
What is a cygwin?
Cygwin is a distribution of popular GNU and other Open Source tools running on Microsoft Windows. The core part is the Cygwin library which provides the POSIX system calls and environment these programs expect.
What compilers link against Cygwin?
The compilers provided by the mingw64-i686-gcc and mingw64-x86_64-gcc packages link against standard Microsoft DLLs instead of Cygwin. This is desirable for native Windows programs that don't need a UNIX emulation layer.
Does Cygwin use SAM?
Although these files can still be used, since Cygwin 1.7.34, new installations now use the SAM/AD databases directly.
How to get mysql output?
Easy solution? Download Console2, and under settings you can point it to the cygwin shell. Restart Console2, run mysql and the output appears.
Is there a workaround for CYGWIN?
There may be a workaround in either the CYGWIN sytem properties or in bash, but I've never taken the time to work this one out.
Can Win32 write to #2?
The Win32 MySQL can write properly to #2, but not #1, because Win32 MySQL cannot probe stdin properly (thanks @PeterNore)
Where is the bash terminal on Cygwin X?
The default settings will bring up Cygwin-X as an icon in the system tray, plus a bash terminal in the top left of the screen. To avoid confusion, ||| close the bash terminal ||| click on the system menu at the upper left icon of the toolbox to dismiss it from the screen. Restoring the toolbox is available by right-clicking on the Exceed icon and selecting Tools -> Toolbar -> Show.
Does Cygwin X restrict localhost?
If a clock appears, then Cygwin-X settings don't restrict connections to localhost only. Go back to the instructions for Cygin-X and make sure that the host access control list is enabled.
