Readline Variables

inputrc

set\fP variable-name\fP value\fP

bell-style (audible): Controls what happens when readline wants to ring the terminal bell. If set to none\fP, readline never rings the bell. If set to visible\fP, readline uses a visible bell if one is available. If set to audible\fP, readline attempts to ring the terminal's bell.
comment-begin (``#''): The string that is inserted when the readline insert-comment command is executed. This command is bound to M-# in emacs mode and to # in vi command mode.
completion-ignore-case (Off): If set to On\fP, readline performs filename matching and completion in a case-insensitive fashion.
completion-query-items (100): This determines when the user is queried about viewing the number of possible completions generated by the possible-completions\fP command. It may be set to any integer value greater than or equal to zero. If the number of possible completions is greater than or equal to the value of this variable, the user is asked whether or not he wishes to view them; otherwise they are simply listed on the terminal.
convert-meta (On): If set to On\fP, readline will convert characters with the eighth bit set to an ASCII key sequence by stripping the eighth bit and prefixing an escape character (in effect, using escape as the meta prefix\fP).
disable-completion (Off): If set to On\fP, readline will inhibit word completion. Completion characters will be inserted into the line as if they had been mapped to self-insert\fP.
editing-mode (emacs): Controls whether readline begins with a set of key bindings similar to emacs\fP or vi\fP. editing-mode can be set to either emacs or .BR vi .
enable-keypad (Off): When set to On\fP, readline will try to enable the application keypad when it is called. Some systems need this to enable the arrow keys.
expand-tilde (Off): If set to on\fP, tilde expansion is performed when readline attempts word completion.
horizontal-scroll-mode (Off): When set to On\fP, makes readline use a single line for display, scrolling the input horizontally on a single screen line when it becomes longer than the screen width rather than wrapping to a new line.
input-meta (Off): If set to On\fP, readline will enable eight-bit input (that is, it will not strip the high bit from the characters it reads), regardless of what the terminal claims it can support. The name meta-flag is a synonym for this variable.
isearch-terminators (``C-[C-J''): The string of characters that should terminate an incremental search without subsequently executing the character as a command. If this variable has not been given a value, the characters ESC\fP and C-J\fP will terminate an incremental search.
keymap (emacs): Set the current readline keymap. The set of valid keymap names is emacs, emacs-standard, emacs-meta, emacs-ctlx, vi, vi-command\fP, and .IR vi-insert . vi\fP is equivalent to vi-command\fP; emacs\fP is equivalent to emacs-standard\fP. The default value is .IR emacs ; the value of editing-mode also affects the default keymap.
mark-directories (On): If set to On\fP, completed directory names have a slash appended.
mark-modified-lines (Off): If set to On\fP, history lines that have been modified are displayed with a preceding asterisk (*\fP).
output-meta (Off): If set to On\fP, readline will display characters with the eighth bit set directly rather than as a meta-prefixed escape sequence.
print-completions-horizontally (Off): If set to On\fP, readline will display completions with matches sorted horizontally in alphabetical order, rather than down the screen.
show-all-if-ambiguous (Off): This alters the default behavior of the completion functions. If set to .BR on , words which have more than one possible completion cause the matches to be listed immediately instead of ringing the bell.
visible-stats (Off): If set to On\fP, a character denoting a file's type as reported by stat\fP(2) is appended to the filename when listing possible completions.
