Title: Nu Command Equivalents in Other Languages (Continued)

Summary

This section continues listing Nu shell commands and their equivalents in SQL, .Net LINQ (C#), PowerShell, and Bash. Commands covered include system memory (`sys mem`), table formatting (`table`), sequence selection (`take`, `take until`, `take while`), benchmarking (`timeit`), data conversion (`to`), file creation (`touch`), duplicate removal (`uniq`), record modification (`update`, `upsert`), version information (`version`), environment variable manipulation (`$env.FOO = "bar"`, `with-env`), conditional filtering (`where`), and command location (`which`).
