Answer the questions in Linux command 1. Create a single command to read a file called program.c and write a file called unreadable.c, by replacing all newlines and tabs with spaces, and replacing all multiple consecutive spaces with a single space. The result should still be a legal C program but not exactly readable. 2. Write a single shell command line, possibly consisting of multiple commands (separated by semicolons), that will create a file diffs.txt containing a list of all files found in my Documents directory that aren’t also found in yours. Assume your current working directory is your home directory.
can someone help me with : Description of environment concepts Description of i/o redirection Description of the process concept, and the differences between background and foreground execution A description of the follwowing operations and commands : cd- change the current default directory to.

This command should also change the PWD environment variable. clr - clear the screen. dir- list the contents of directory environ - list all the environment strings echo - display on the display followed by a new line (multiple spaces/tabs may be reduced to a single space) help - display the user manual using the more filter pause - pause operation of the shell until 'Enter' is pressed quit - quit the shell

I need help with a Linux assignment. See below info: Rewrite the command so it makes sense to you. See the fdisk example: Name- fdisk Disk partition tool used to divide a hard disk into logical disks (partitions). Syntax- fdisk [-u] [-b sectorsize] [-C cyls] [-H heads] [-S sects] device -b sectorsize Specify the sector size of the disk (512/1024/2048) -C cyls Specify the number of cylinders in a disk. -H heads Specify the number of heads of the disk -S sects Specify the number of sectors per track of the disk -u Partition table sizes listed need to be given in sectors instead of cylinders
find The find command takes a pattern as a command-line argument and recur- sively searches through directories to find a filename matching that pattern. It should print a relative path starting with "./" for every file/directory that matches. For example, running ./find 1s.c from within the hw2 directory should print ./1s.c. If run from the parent directory, the output would be . /hw2/1s.c. There may be multiple matches. If we run ./find .c from within the hw2 directory, we should see: ./find.c ./1s.c ./tree.c The output does not need to be sorted. If nothing matches, it shouldn't print anything. Pattern matching should be case sensitive.
