Cygwin is used to port applications that were written for Unix or Linux to a Windows environment.
There is very little difference in the C compiler between Unix and Linux; in some cases (the gcc compiler) it is the same. The differences come in when using system calls; some system calls do not exist in Unix or Linux, although most do. The program I work on compiles the same way (for the most part) between all commercial versions of Unix and several variants of Linux. In other words, the code is fairly portable across platforms.
Unix is not open source, it is proprietary. Linux is the open-source version of Unix.
Unix is a classification of operating systems that conform to a certain specification, based on that of the original Unix operating system created by AT&T. Systems certified as Unix can differ drastically, but must meet at least certain common elements. Solaris is an implementation of Unix created by Sun Microsystems. Linux is a family of operating systems based on a kernel written by Linus Torvalds. It shares some design goals and similarities with Unix, but has several advanced features and is not completely compatible with Unix. Legally, for a system to be described as "Unix", it must undergo a certification process. No Linux distribution has ever undergone this (very expensive) certification process to make it compliant with Unix standards. Solaris uses older, POSIX-compliant utilities. Linux typically uses GNU utilities, which are generally compatible, but have different command switches and more features. This is beginning to change with the OpenSolaris project, which incorporates many GNU utilities. Solaris and Linux both have features that the other lacks, and are not found in other Unix implementations either. These include DTRace and the ZFS file system (in Solaris) and dynamically loadable kernel modules and epoll (in Linux).
You look at the file. A program such as Windows Explorer - or the equivalent in other operating systems - can tell you the size. Also, a command such as "dir" (in Windows), or "ls" (in Linux or Unix).
No, it is unix-based but Linux is a kernel not an operating system.Ubuntu,Linux Mint,Debian,and puppy Linux,ect. are OS's that use the Linux kernel.
Linux is an operating system, like Windows, that runs on the Linux Kernel, which is based off of UNIX.
maz 0S 10, windows xp or vista, Linux or unix
Yes
The Linux kernel is named for its creator, Linus Torvalds. The practice of appending an X was for Unix and Unix-like systems.
Because Linux evolved from UNIX, but Windows evolved from DOS.
what are similarities and differences between linux and unix?
The "basic concept" of Linux is a free and open-source Unix-like kernel.
Vista is not the best operation system. Windows 7 is faster and technically superior, Windows XP is stable and mature and unix/linux is more secure.
There are Windows Server, Linux, BSD, and even Apple's own server
Yes.
Windows, Linux, Ubuntu, Linux Mint, the list is huge!
