Unix/Linux Interview Questions & Answers
JIL is a specification language, with its own syntax, that is used to describe when, where, and how a job should run. When you enter the jil command, you get the jil command prompt, at which you can enter the job definitions one line at a time using this special language. When you exit the jil command-line interface, the job definition is loaded into the database. Alternatively, you can enter the definition as a text file and redirect the file to the jil command. In this case, the jil command activates the language processor, interprets the information in the text file, and loads this information in the database. Question 4. Answer : The job has not yet been processed. Either the job has never been run, or its status was intentionally altered to turn off its previous completion status.

Question 5. The box job is started now. After starting the box job user immediately realized that there is a mistake in command script name in Job C. Thus, he ensures the job will run proper way. Question 6. Answer : This job is removed from all conditions and logic, but is still defined. Operationally, this condition is like deactivating the job. Question 7. Answer : The difference between on hold and on ice is that when an on hold job is taken off hold, if its starting conditions are already satisfied, it will be scheduled to run, and it will run. On the other hand, if an on ice job is taken off ice, it will not start, even if its starting conditions are already satisfied. This job will not run until its starting conditions reoccur. The other major distinction is that jobs downstream from the job that is on ice will run as though the job succeeded. Whereas, all dependent jobs do not run when a job is in on hold—nothing downstream from this job will run.

The system call mknod creates special files in the following sequence: kernel assigns new inode, Sets the file type to indicate that the file is a pipe, directory or special file, If it is a device file, it makes the other entries like major, minor device numbers. For example: If the device is a disk, major device number refers to the disk controller and minor device number is the disk. Question 9. Answer : The privileged mount system call is used to attach a file system to a directory of another file system; the unmount system call detaches a file system. When you mount another file system on to your directory, you are essentially splicing one directory tree onto a branch in another directory tree. The first argument to mount call is the mount point, that is , a directory in the current file naming system. The second argument is the file system to mount to that point.

Question Answer : Inode has 13 block addresses. The first 10 are direct block addresses of the first 10 data blocks in the file. The 11th address points to a one-level index block. The 12th address points to a two-level double in-direction index block. The 13th address points to a three-level triple in-direction index block. This provides a very large maximum file size with efficient access to large files, but also small files are accessed directly in one disk read. What Is A Shell? Answer : A shell is an interactive user interface to an operating system services that allows an user to enter commands as character strings or through a graphical user interface.

The shell converts them to system calls to the OS or forks off a process to execute the command. System call results and other information from the OS are presented to the user through an interactive interface. Commonly used shells are sh,csh,ks etc. Answer : While booting, special process called the 'swapper' or 'scheduler' is created with Process-ID 0. The swapper manages memory allocation for processes and influences CPU allocation. The swapper inturn creates 3 children: the process dispatcher, dbflush with IDs 1,2 and 3 respectively. Process dispatcher gives birth to the shell. Unix keeps track of all the processes in an internal data structure called the Process Table listing command is ps -el. Answer : Unix identifies each process with a unique integer called ProcessID. Every process is associated with a particular user called the 'owner' who has privileges over the process.

Unix / Linux Questions And Answers
I have collected many UNIX command interview questions and already shared them but I found that except system admin jobs, many programming job interviews only focus on general UNIX commands like chmod , find or grep , and fundamentals like finding files and directories, managing file space, networking commands , checking process status and managing file permissions. In this article, we will see such kinds of frequently asked interview questions and answers from the UNIX and Linux operating systems. As I said they are very fundamental and can be asked in any company. If you come across any other frequently asked Linux questions which are not on this list feel free to suggest. Btw, if you are new to Linux then I also suggest you to first go through comprehensive and hands-on Linux courses to learn basics and essential commands.

Linux Basic Questions And Answers For System Admins
Just like any other typical operating system, Linux has all of these components: kernel, shells and GUIs, system utilities, and an application program. What makes Linux advantageous over other operating system is that every aspect comes with additional features and all codes for these are downloadable for free. In general, one desktop environment, like KDE or Gnome, is good enough to operate without issues. It's all a matter of preference for the user, although the system allows switching from one environment to another. Some programs will work in one environment and not work on the other, so it could also be considered a factor in selecting which environment to use. BASH follows no such convention. This so-called Free software movement allows several advantages, such as the freedom to run programs for any purpose and freedom to study and modify a program to your needs. It also allows you to redistribute copies of software to other people, as well as the freedom to improve software and have it released for the public.

Assuming you are the system administrator or the owner of a file or directory, you can grant permission using the chmod command. TXT, which is assigned to groups and others. Linux assigns numbers at the end of the drive identifier. Hard links point directly to the physical file on disk, and not on the pathname. This means that if you rename or move the original file, the link will not break since the link is for the file itself, not the path where the file is located.
