Change the filename used for reading and writing with the paste buffer. If the exchange-file parameter is omitted,
screenreverts to the default of /tmp/screen-exchange. The following example will paste the system's password file into the screen window (using the paste buffer, where a copy remains):C-a : bufferfile /etc/passwd C-a < C-a ] C-a : bufferfile
Reads the contents of the specified file into the paste buffer. You can tell screen the encoding of the file via the
-eoption. If no file is specified, the screen-exchange filename is used.
Writes the contents of the paste buffer to the specified file, or the public accessible screen-exchange file if no filename is given. This is thought of as a primitive means of communication between
screenusers on the same host. If an encoding is specified the paste buffer is recoded on the fly to match the encoding. See also C-a <ESC> (see Copy).
