nu-shell

Nushell treats all data as structured tables — lists of records with rows and columns. Every file and command output becomes a table you can filter, transform, and combine.

File I/O & Parsing

Files auto-detect from extension. Pipe command output into tables:

open data.csv                # CSV → table
df -h | detect columns       # Command output → table
$data | save -f output.csv   # Write (overwrite with -f)
