yank

Yank terminal output to clipboard.

Description

Read input from stdin and display a selection interface that allows a field to be selected and copied to the clipboard. Fields are either recognized by a regular expression using the -g option or by splitting the input on a delimiter sequence using the -d option.

Using the arrow keys will move the selected field. The interface supports several Emacs and Vi like key bindings, consult the man page for further reference. Pressing the return key will invoke the yank command and write the selected field to its stdin. The yank command defaults to xsel(1) but could be anything that accepts input on stdin. When invoking yank, everything supplied after the -- option will be used as the yank command, see examples below.

Motivation

Others including myself consider it a cache miss when resort to using the mouse. Copying output from the terminal is still one of the few cases where I still use the mouse. Several terminal multiplexers solves this issue, however I don't want to be required to use a multiplexer but instead use a terminal agnostic solution.

Examples

• Yank an environment variable key or value:

  env | yank -d =

• Yank a field from a CSV file:

  yank -d \", <file.csv

• Yank a whole line using the -l option:

  make 2>&1 | yank -l

• If stdout is not a terminal the selected field will be written to stdout and exit without invoking the yank command. Kill the selected PID:

  ps ux | yank -g [0-9]+ | xargs kill

• Yank the selected field to the clipboard as opposed of the default primary clipboard:

  yank -- xsel -b

Installation

Arch Linux

On AUR:

yaourt -S yank

Debian
