Overview

vselect is a simple utility for visually selecting a subset from a list using a curses-like interface. Inputs are taken from stdin and output is sent to stdout.

Each line in the input is one possible selection. One or more of these can be selected, and the output is printed one item per line.

For example, to count the number of lines in a few files in the current directory

ls -1 | vselect | xargs wc -l

The vselect stage of the pipeline will bring up a list view of the inputs from the first stage. After exiting from vselect, its outputs are fed into the next stage.

Key bindings

  • Enter: exit with current selection
  • q: exit without a selection
  • x: mark current item as selected
  • j: move down
  • k: move up

Selected items

The current selection is either:

  1. the set of all marked items;
  2. or, if there are no marked items the currently active item in the list
