Linux CLI - Viewing and Editing Files

You want to search for the word 'error' inside a large log file app.log while viewing it with less. Which command allows you to do this efficiently?

Amore app.log | grep error

Bgrep error app.log | less

Ccat app.log | less error

Dless app.log and then type /error

Step-by-Step Solution

Solution:

Step 1: Understand searching inside less
less supports interactive search by typing '/' followed by the search term.
Step 2: Analyze other options
more piped to grep filters output but does not allow interactive search; cat with less error is invalid syntax; grep piped to less shows only matching lines, not full file.
Final Answer:
less app.log and then type /error -> Option D
Quick Check:
Use / inside less to search [OK]

Quick Trick: Type /word inside less to search [OK]

Common Mistakes:

Using grep before less losing context
Trying invalid command syntax
Expecting more to support search
Not knowing less interactive features
