# install this program with the name xc and symlink it as xs.
# xc will use the clipboard selection, while xs while use the primary selection
read -r -d '' HELPTEXT <<HELP
Usage: xc [COMMAND]
xc fromxs|toxs
xs [COMMAND]
xs fromxc|toxc
The used X selection is determined by the name the program is called as:
xc: clipboard (Ctrl-C / Ctrl-V)
xs: primary selection (middle mouse button)
For showboth/readboth, the action is done for both selections.
Commands:
show/showboth: show contents of clipboard
(default if no command given)
read/readboth: store input to clipboard
(default if stdin is not a terminal)
sed: modify contents using a sed expression
pipe: modify contents by piping through a command
edit: edit clipboard contents using \$EDITOR
fromxs/toxs: xc only: copy contents from or to primary selection
fromxc/toxc: xs only: copy contents from or to clipboard
