editrc - configuration file for editline library
The editrc file defines various settings to be used by the editline(3)
The format of each line is:
[prog:]command [arg [...]]
command is one of the editline(3) builtin commands. Refer to BUILTIN
COMMANDS for more information.
prog is the program name string that a program defines when it calls
el_init(3) to set up editline(3), which is usually argv. command will
be executed for any program which matches prog.
prog may also be a regex(3) style regular expression, in which case
command will be executed for any program that matches the regular
If prog is absent, command is executed for all programs.
The editline library has some builtin commands, which affect the way that
the line editing and history functions operate. These are based on
similar named builtins present in the tcsh(1) shell.
The following builtin commands are available:
bind [-a] [-e] [-k] [-l] [-r] [-s] [-v] [key [command]]
Without options, list all bound keys, and the editor command to
which each is bound. If key is supplied, show the bindings for
key. If key command is supplied, bind command to key. Options
-e Bind all keys to the standard GNU Emacs-like bindings.
-v Bind all keys to the standard vi(1)-like bindings.
-a List or change key bindings in the vi(1) mode alternate
(command mode) key map.
-k key is interpreted as a symbolic arrow key name, which may be
one of ‘up’, ‘down’, ‘left’ or ‘right’.
-l List all editor commands and a short description of each.
-r Remove a key’s binding.
-s command is taken as a literal string and treated as terminal
input when key is typed. Bound keys in command are
themselves reinterpreted, and this continues for ten levels
command may be one of the commands documented in EDITOR COMMANDS
below, or another key.
key and command can contain control characters of the form
‘^character’ (e.g. ‘^A’), and the following backslashed escape
\r Carriage return
\t Horizontal tab
\v Vertical tab
\nnn The ASCII character corresponding to the octal number
‘\’ nullifies the special meaning of the following character, if it
has any, notably ‘\’ and ‘^’.
echotc [-sv] arg ...
Exercise terminal capabilities given in arg .... If arg is ‘baud’,
‘cols’, ‘lines’, ‘rows’, ‘meta or’ ‘tabs’, the value of that
capability is printed, with “yes” or “no” indicating that the
terminal does or does not have that capability.
-s returns an empty string for non-existent capabilities, rather
than causing an error. -v causes messages to be verbose.
edit [on | off]
Enable or disable the editline functionality in a program.
history list | size n | unique n
The list command lists all entries in the history. The size
command sets the history size to n entries. The unique command
controls if history should keep duplicate entries. If n is non
zero, only keep unique history entries. If n is zero, then keep
all entries (the default).
List the values of all the terminal capabilities (see termcap(5)).
settc cap val
Set the terminal capability cap to val, as defined in termcap(5).
No sanity checking is done.
setty [-a] [-d] [-q] [-x] [+mode] [-mode] [mode] [char=c]
Control which tty modes that editrc won’t allow the user to change.
-d, -q or -x tells setty to act on the ‘edit’, ‘quote’ or ‘execute’
set of tty modes respectively; defaulting to -x.
Without other arguments, setty lists the modes in the chosen set
which are fixed on (‘+mode’) or off (‘-mode’). -a lists all tty
modes in the chosen set regardless of the setting. With +mode,
-mode or mode, fixes mode on or off or removes control of mode in
the chosen set.
Setty can also be used to set tty characters to particular values
using char=value. If value is empty then the character is set to

written by Luke Mewburn, with some sections inspired by tcsh(1).
