where for filters

Filter values based on a row condition.

Signature

> where (row_condition)

Parameters

• row_condition: Filter condition

Notes

This command works similar to 'filter' but allows extra shorthands for working with tables, known as "row conditions". On the other hand, reading the condition from a variable is not supported.

Examples

Filter rows of a table according to a condition

> [{a: 1} {a: 2}] | where a > 1
╭───┬───╮
│ # │ a │
├───┼───┤
│ 0 │ 2 │
╰───┴───╯

Filter items of a list according to a condition

> [1 2] | where {|x| $x > 1}
╭───┬───╮
│ 0 │ 2 │
╰───┴───╯

List all files in the current directory with sizes greater than 2kb

> ls | where size > 2kb

List only the files in the current directory

> ls | where type == file

List all files with names that contain "Car"

> ls | where name =~ "Car"

List all files that were modified in the last two weeks

> ls | where modified >= (date now) - 2wk

Find files whose filenames don't begin with the correct sequential number

> ls | where type == file | sort-by name -n | enumerate | where {|e| $e.item.name !~ $'^($e.index + 1)' } | each {|| get item }
