grep --color=always -E "error|warn" — highlight errors and warnings
grep --color=always -E "error|warn"
Using grep with an extended regex (-E) and the alternation operator allows matching multiple patterns at once. --color=always forces ANSI colour output even when piped, making error and warning lines stand out in log files.
