Linux CLI - File and Directory Operations

Which of the following is the correct pattern to match files named data1, data2, but not data10?

A<code>data?</code>

B<code>data*</code>

C<code>data[1-9]</code>

D<code>data??</code>

Step-by-Step Solution

Solution:

Step 1: Understand the pattern data[1-9]
This matches 'data' followed by exactly one digit from 1 to 9, so it matches 'data1' and 'data2' but not 'data10'.
Step 2: Check other patterns
data? matches 'data' plus any one character (including letters), data* matches 'data' plus any characters (including 'data10'), and data?? matches 'data' plus exactly two characters (so it matches 'data10').
Final Answer:
data[1-9] -> Option C
Quick Check:
Square brackets match one character from set [OK]

Quick Trick: Use [ ] to match one character from a range [OK]
