Which of the following is the correct syntax to create an alias named ll for ls -l in your shell setup?

Aalias ll='ls -l'

Bexport ll='ls -l'

Calias ll=ls -l

Dset alias ll='ls -l'

Step-by-Step Solution

Solution:

Step 1: Recall alias syntax
The correct way to create an alias is using the keyword alias followed by the name, an equals sign, and the command in single quotes.
Step 2: Check each option
alias ll='ls -l' matches the correct syntax. export ll='ls -l' uses export which is for variables, not aliases. alias ll=ls -l misses quotes, causing syntax errors. set alias ll='ls -l' uses an invalid command.
Final Answer:
alias ll='ls -l' -> Option A
Quick Check:
Alias syntax = alias name='command' [OK]

Quick Trick: Use alias name='command' with quotes for shortcuts [OK]
