Where is this kind of usage (stuff ^X) documented? I did not found it in
The 'stuff' command is in the screen manpage:
Stuff the string string in the input buffer of the current window.
This is like the "paste" command but with much less overhead. Without
a parameter, screen will prompt for a string to stuff. You cannot
paste large buffers with the "stuff" command. It is most useful for key
bindings. See also "bindkey".
The usage they are using is a combo of using 'stuff' with the '-X' flag
which lets you send commands to a screen session via the shell (rather
than from the : prompt inside of screen).
I'm actually asking about the ^X part. That's to say where is it documented
that the *stuff* command would interprete the ^X as CTRL-X?
It's not spelled out that the 'stuff' command would interpret ^X as
CTRl-X, but it does say to use the caret notation early in the
documentation under the "DESCRIPTION" header:
Screen does not understand the prefix "C-" to mean control, although
this notation is used in this manual for readability. Please use
the caret notation ("^A" instead of "C-a") as arguments to e.g. the
escape command or the -e option. Screen will also print out control
characters in caret notation.
I also found that *stuff* understands C-style escapes (like \t, \n and
\040) but I did not found the related document either.
Again, not spelled out for the 'stuff' command, but it is mentioned
under the instructions for 'bind' (and 'stuff' does mention that it is
often used as a 'bind' command:
bind [-c class] key [command [args]]
Bind a command to a key. By default, most of the commands provided by
screen are bound to one or more keys as indicated in the "DEFAULT KEY
BINDINGS" section, e.g. the command to create a new window is bound to
"C-c" and "c". The "bind" command can be used to redefine the key
bindings and to define new bindings. The key argument is either a
single character, a two-character sequence of the form "^x" (meaning
"C-x"), a backslash followed by an octal number (specifying the ASCII
code of the character), or a backslash followed by a second character,
such as "\^" or "\\". The argument can also be quoted, if you like.
If no further argument is given, any previously established binding for
this key is removed. The command argument can be any command listed in
Sometimes, one has to take the 'well, if it works there, maybe it works
here' attitude and try it.
