Bash Scripting - Loops

What is the output of this script if the current directory contains files: file1.txt, file2.log, and a directory named docs?
for item in *; do if [ -d "$item" ]; then echo "Dir: $item"; else echo "File: $item"; fi; done

ADir: docs Dir: file1.txt Dir: file2.log

BFile: docs File: file1.txt File: file2.log

CDir: docs File: file1.txt File: file2.log

DFile: file1.txt File: file2.log

Step-by-Step Solution

Solution:

Step 1: Understand the loop and condition
The loop iterates over all items in the current directory. For each item, it checks if it is a directory with '[ -d "$item" ]'.
Step 2: Determine output for each item
'docs' is a directory, so it prints 'Dir: docs'. 'file1.txt' and 'file2.log' are files, so it prints 'File: file1.txt' and 'File: file2.log'.
Final Answer:
Dir: docs File: file1.txt File: file2.log -> Option C
Quick Check:
Directory check prints Dir, else File = A [OK]

Quick Trick: Use '[ -d ]' to check if item is directory [OK]
