How do you find out what DOS Commands are available in Linux?
There is none. For starters, you have it backwards, DOS actually copied most of its commands from Unix (The rest came from CP/M.), which Linux is inspired by. Commands like "cd" and "dir" were Unix commands long before DOS even existed.
What are the commands used in Linux but not in Unix?
There is no answer to this question. Under UNIX and Linux, commands are either shell native or external programs found on the path (which usually includes /bin /sbin /usr/bin and ~/bin) Most UNIX and distros allow the admin to choose a shell program of choice and modify the contents of other directories and many admins allow individual users to change their personal shell and add additional executable files adding more commands. That being the case, theoretically any command can be valid under almost any UNIX or Linux. YMMV.
Do Unix commands work in Linux?
The ones that are listed as part of a standard (such as Posix) will work in all UNIX systems (but not all systems, such as Windows command prompt). A lot of UNIX vendors add commands that only work in their version of UNIX, so they aren't as portable across systems as others.
What is unix schedular and how it work?
There are two standard job schedulers in Unix - 'at' and 'cron'. Neither can be answered in a short answer so it is suggested that you do an internet search on either of these two commands, or use the 'man' or 'info' command on 'at' or 'cron' on your Unix/Linux system.
How can you learn all of the Unix commands?
It would take a very long time to learn all of the Unix commands, and frankly, that isn't necessary. Most Unix users have a subset of commands they use all the time, and that is how they learn them.
What Linux super-user account is built into Linux?
With most Unix-derived systems, "root" is the super-user account.
What is the difference between C and Linux?
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.
What is the relationship of POSIX1 to Linux?
POSIX is a standard designed to ensure API compatibility between Unix and Unix-like operating systems operating systems. Linux implements most of the POSIX standard, but is not certified as such.
Are unix hosting and Linux hosting the same?
Linux hosting and Unix hosting are not exactly the same thing. Linux hosting and Unix hosting refer to the software operating system employed by the servers of the host. The primary communication being made when a server is described as Unix or Linux is that it is not a Microsoft product. Unix comes in several proprietary versions, Sun Microsystems (now Oracle) and AT&T are two well known commercial versions of Unix. They own and control intellectual property associated with Unix. Linux is a nonproprietary version of Unix. There are many flavors of this. All are "open source." The intellectual property is controlled by one of the various open source models, GPL being the most well know. If a person says they have a Unix server, they may or may not mean the proprietary version of Unix. For many people, unix is a generic reference and can mean Unix or Linux. If a person says they have a Linux server, then it is a Linux operating system. It may be one of over a hundred different types of Linux, but it is based on an open source version of Unix. Note that it is possible to co-mingle the proprietary and nonproprietary versions of Unix, but this is not typically a matter of concern unless you are an expert or unless you are using Apple's version of "open source" Linux. Apple's version works pretty much like open source Linux, mostly, sometimes.
Unix supports DOS commands or not?
Most of MS-DOS' commands were based on those of Unix and CP/M. 'cd', 'dir', 'clear', and 'echo' are usually found in both. MS-DOS added it's own commands, however, and made some different from those of existing versions of Unix, and no one saw any reason to change the names of existing ones in Unix.
Which are the five most commonly used operating systems in banks?
Most of the BANKS works on Mainframes which generally uses UNIX operating systems. But a BANK can use UNIX and flavours of LINUX (which is a UNIX flavor) and Windows Server ...
The most common operating system are?
The most common ones are windows family, Mac OS, Linux and Unix.
