Usage

Overview

The pick utility allows users to select from a set of choices using an curses(3) interface with fuzzy search functionality.

The choices are read from stdin, and the selected choice written to stdout.

The options are as follows:

-d

Read and display descriptions. Input lines will be split into two parts by the last occurrence of IFS. Both parts will be displayed but only the first part will be used when searching.

-h

Output a help message and exit.

-K

Disable toggling of keypad transmit mode. Useful when running pick from within another interactive program which already has set the correct transmit mode.

-o

Output description of selected choice on exit.

-q query

Supply an initial search query.

-S

Disable sorting. Only filter the choices instead of additionally sorting by score. This option can be toggled from within the interface, see COMMANDS.

-v

Output the version and exit.

-x

Enable the use of the alternate screen terminal feature. This is the default.

-X

Disable the use of the alternate screen terminal feature.
