  1. How do you search for text and files in Linux using grep and find?

    grep searches inside files for lines matching a pattern, for example grep -rn "error" logs/. find searches the directory tree for files by name, type, size or age, for example find . -name "*.log" -mtime -1. They are often combined to search text inside a chosen set of files.
