What are common `cat` options?

Common cat options include:

• -A: Show all non-printing characters (equivalent to -vET).
• -b: Number non-blank output lines.
• -E: Display a $ at the end of each line.
• -n: Number all output lines.
• -s: Suppress repeated empty output lines.
• -T: Display TAB characters as ^I.
• -v: Use ^ and M- notation for non-printing characters, except for line feed (LF) and TAB.

These options help in managing and manipulating text files effectively in Linux environments.
