Bash Scripting - String Operations

Consider this Bash snippet:

file="archive.tar.gz"
echo ${file%*.gz}

It outputs archive.tar. You want to remove the entire suffix .tar.gz. What is the fix?

AUse ${file%%*.gz} to remove the longest matching suffix

BUse ${file%.gz} to remove only '.gz' suffix

CUse ${file#*.tar.gz} to remove prefix instead

DUse ${file%.tar} to remove only '.tar' suffix

Step-by-Step Solution

Solution:

Step 1: Understand why ${file%*.gz} removes only '.gz'
Single % removes shortest suffix matching *.gz pattern, so it matches '.gz' (with * matching empty).
Step 2: Use %% to remove longest suffix
Double %% removes longest matching suffix, so ${file%%*.gz} removes entire '.tar.gz'.
Final Answer:
Use ${file%%*.gz} to remove the longest matching suffix -> Option A
Quick Check:
%% removes longest suffix, % removes shortest [OK]

Quick Trick: Use %% to remove longest suffix pattern [OK]
