Unix/Linux I have a few queries about shell
Step by step
Solved in 3 steps with 2 images
- Linux: The complete path and filename for the configuration file that lists shared library directories is...unix Cd-changes the current working directory in various Operating Systems (OS). Pwd-acronym for p rint w orking d irectory-prints the working directory. Mkdi- allows users to create directories or folders as they are referred to in some Operating Systems (OS). Rm- cat Echo Ls Ln Echo and .. in the pathnameExplain how UNIX/Linux and Windows use least privilege differently.
- OS-level formatting produces a file that is recognized asMINIX Programming - Please provide screenshots of what was changed so I can read it better and how to find the file Modify the MINIX 3 scheduler to keep track of how much CPU time each user process has had recently. When no task or server wants to run, pick the user process that has had the smallest share of CPU.Parallel:- Implement the parallel utility that has 3 command line arguments. This will execute 4 copies of the sleep process for 10 seconds. Your program should allow an arbitrary number of command line arguments for the process to be run in parallel. The parent process should wait for all child processes to finish before exiting back to the shell. If the format of the command is not recognized (e.g. the first argument is not an integer), an error can be displayed. All your code should be contained in the parallel.c file, and the Makefile. ./parallel<processes><cmd><args> For example, if you type: ./parallel 4 sleep 10 OUTPUT: SUCCESS in running 4 parallel sleep tasks
- Where all the data or files of a particular user is saved in Unix file system?List and describe the seven fundamental fields of a directory entry in MS-DOS (do not include the reserved field).- Assume a system has a capacity of 2,000 users. Propose a UNIX security mechanism that enables 1,990 people access to a single file called "MPX.pdf." How would you handle the remaining ten people who are not permitted to view the file?
- In Minix or UNIX-like operating systems, when a file system is mounted, the directory chosen for the mount point must be an empty directory. True FalseExplain the process of manually booting up a UNIX-like system through GRUB.(True/False): The FAT32 file system allows the setting of individual user permissions for directories,but not files
