wpaste pastes the nominated X11 cut buffers(s) to standard output. The default is the first cut buffer.

Note that the cut buffers are numbered starting from 0.

Simple integer arguments pick a cut-buffer.

For wcopy, the argument number picks a cut-buffer to copy the standard input to. (Subsequent copies are taken from the first nominated buffer - it does not try to re-read the input!))

echo fred | wcopy 1 2

This puts the word "fred" into the 2nd and 3rd cut-buffers.

wpaste | tr A-Z a-z | wcopy 1

This copies the clipboard then translates all upper case letters to lower in the 1st cut buffer and copies the result into the 2nd.

wpaste 0 | fmt -w 66 | sed 's/^/> /' | wcopy 1

This reformats the clipboard to paragraphs with lines no longer than 66 characters, inserts typical email quoting characters, and copies the output to the 2nd cut-buffer.

wpaste | sed 's/^> *//' | wcopy

This removes email quotes from the start of lines in the clipboard and replaces the clipboard with the un-quoted material.

wpaste > ~/.myclipboard

Copies the clipboard into a location where it can be pixked up from other computers (e.g. even from a Windows machine) - as per the file permissions you choose for the ".myclipboard" file.
