# Write a single Linux command to redirect the stderr from the command:<br>cat a.txt b.txt c.txt to a file called error.txt contained in the “assignments” directory. (overwrite previous file’s contents and use only relative pathnames)
# Write a single Linux command: cat ~/a.txt ~/b.txt ~/c.txt and redirect stdout to a file called “good.txt” to the “tests” directory and stderr to a file called “bad.txt” to the “tests” directory. (overwrite previous contents for both files and use only relative-to-home pathnames).
# Write a single Linux command to redirect the stdout from the command:<br>'''cat a.txt b.txt c.txt ''' to a file called wrong.txt contained in the “projects” directory and throw-out any standard error messages so they don’t appear on the screen (append output to existing file and use only relative pathnames).<br><br># Write a single Linux '''pipeline command''' to display a detailed listing of the “projects “directory '''projects''' directory but pause one screen at a time to view and navigate through all of the directory contents. Use a relative-to-home pathname.
# Write a single Linux '''pipeline command''' to display the sorted contents (in reverse alphabetical order) of the “linux” directory. Use a relative pathname.
# Assume that the text file called “'''.answers.txt” txt'''” contains 10 lines. Write a single Linux pipeline command to only displays lines 5 through 8 for this file. Use only relative pathnames.# Write a single Linux '''pipeline command''' to only display the contents of the “assignments” directory whose filenames match the pattern “murray” “'''murray'''” (both upper or lowercase). Use an absolute pathname.
# Write a single Linux '''pipeline command''' to display the number of characters contained in the file called “.answers.txt”. Use a relative-to-home pathname.
# Write a single Linux '''pipeline command''' to display the number of lines contained in the file called “questions.txt”. Use a relative pathname.
