In MS-DOS, you want to display the contents of C:\AUTOEXEC.BAT but the output scrolls too fast. Which correct command paginates the output one screen at a time?
-
ATYPE C:\AUTOEXEC.BAT | MORE
-
BTYPE C:\AUTOEXEC.BAT /P
-
CTYPE C:\AUTOEXEC.BAT/MORE
-
DTYPE C:\AUTOEXEC.BAT | PAUSE
-
ETYPE C:\AUTOEXEC.BAT | MORE.
Answer
Correct Answer: TYPE C:\AUTOEXEC.BAT | MORE
Explanation
Introduction / Context:Large text files printed to the screen with TYPE can scroll past the visible buffer. Piping output through a pager is a standard console technique to read content screen by screen, improving readability without editing the file.
Given Data / Assumptions:
- The file C:\AUTOEXEC.BAT exists and is readable.
- MS-DOS shell supports pipes and the MORE filter.
- User wants interactive pagination.
Concept / Approach:The pipe character (|) connects the output of one command to the input of another. In DOS, piping TYPE into MORE paginates text by waiting for a keypress at each screenful. Slashes like /P are not valid for TYPE pagination (they are used by other commands), and adding stray punctuation (like a trailing dot) breaks the command.
Step-by-Step Solution:
1) Run: TYPE C:\AUTOEXEC.BAT | MORE2) Read the first screen of text; press a key to continue.3) Repeat until the end of file.4) Optionally redirect to a file or printer instead of paging if required.Verification / Alternative check:Try TYPE C:\AUTOEXEC.BAT alone and observe rapid scrolling; then compare with the piped command to confirm pagination works.
Why Other Options Are Wrong:
- TYPE ... /P or /MORE: TYPE does not support these switches for paging.
- TYPE ... | PAUSE: Pauses once, not paginated viewing.
- TYPE ... | MORE.: Trailing dot invalidates the pager command.
Common Pitfalls:Forgetting the space before and after the pipe or mis-typing the path, which leads to “File not found.”
Final Answer:TYPE C:\AUTOEXEC.BAT | MORE
